Habitat:-In sand under coral slab at 3 m Description:-Source Original description Shell small for genus, elongated, with high spire; shell surface highly sculptured with large, very numerous, closely packed spiral threads, giving shell rough texture; shoulder angled; spire whorls ornamented with 4 spiral cords; protoconch exserted, mammillate; shell color pinkish-brown with scattered large, irregular blue patches; mid-body with large, wide pale blue band; mid-body band sometimes overlaid with irregular small, dark brown flammules and patches; some specimens uniformly deep blue color, without brown patches; protoconch and early whorls bright salmon-orange; interior of aperture purplish-brown with wide white band. Discussion:-Conus cuna is superficially similar to the common and widespread Conus mus Hwass, 1792, but differs in being a more slender and elongated shell with a higher spire, and in having bright salmon-orange early whorls and protoconch. ---------- Conus cuneiformis Smith, 1877 Pictures: Picture Link: Lectotype in NHMUK Mike Filmer Published in: J.

Meth. Hist. Nat. des Vers. Vol. 1, p. 602 Ocean geography: West Atlantic and Caribbean Type Locality: Aruba; Island of Curaçao, (erroneous), corrected (Vink & von Cosel) Aruba, (Netherlands Antilles). Type Data: A representative type figure has been recorded as: Tableau (1798: pl. 316, fig. 4) Nomenclature: An available name Taxonomy: A valid species Current Group Names:- Family:-CONIDAE SubFamily:-PUNCTICULIINAE Genus:-Tenorioconus Species:-curassaviensis Synonyms:- There are no junior synonyms Geographic Range:-Aruba Dutch Antilles Habitat:-Found at shallow depths of 2-5 m Description:-Source Vink A relatively fat shell, 40 to 50 mm., with moderately elevated to high, slightly concave- sided spire. Body whorl convex- sided, early whorls tuberculated, later whorls smooth and often somewhat canaliculate. Surface with weak spiral threads near the base, but not granulated, except in small juvenile specimens. 'Internal restriction' within the aperture weak to very weak. Animal bright red, operculum small but somewhat longish, about 1/6 ofaperture height. Radular tooth described and pic- tured by Vink & Cosel. Periostracum thin, yellowish. Colour white with maculations or isolated patches of yellowish brown, orange, reddish brown or black. Background not always evenly white, but showing pale bluish and pinkish hues causing the dark areas to be often not well delimited. In addition spiral rows of white and brown dots and dashes placed close together. Discussion:-C. curassaviensis could be confused with C. mappa (which is larger with a more straight-sided body whorl, more canaliculate spire whorls and a more developed 'internal restriction' within the aperture), with C. aurantius (which is more slender with a tuberculated shoulder of the body whorl) and with C. pseudaurantius (which has a lower spire and a tuberculated shoulder of the body whorl). ---------- Conus curralensis Rolan, 1986 Pictures: Picture Link: Holotype in MNCM Manolo Tenorio Picture Link: Paul Kersten Radula Picture: Manuel Tenorio & Emilio Rolán Published in: Publ. Ocas. Soc. Port. Malac. no. 6, p. 10, f. 1B Ocean geography:East Atlantic and West Africa Type Locality: Curral, Santa Luzia; 1-3 m Type Data: Holotype in MNCM deposited and catalogued Type Size: 20.7 x 12.3 mm Nomenclature: An available name Taxonomy: A valid species Current Group Names:- Family:-CONIDAE SubFamily:-PUNCTICULIINAE Genus:-Africonus Species:-curralensis Synonyms:- There are no junior synonyms Geographic Range:-Santa Luzia, Cape Verde Islands Habitat:-Found at depths around 2m among rocks Description:-Source Original description translation The seashell is obconical with slightly raised spire, barely stepped. Its color is always a little gaudy, oscillating among cream, yellow, siena, light green olive and intermediate tones. The pattern consists of white areas, mostly in form of zig-zag or of oblique lines, that dominate in a band situated a little under the middle of the last whorl, in the shoulder and, frequently, in another narrow band between them. Spire also has white areas alternating with the darker color of the background. Frequently can be appreciated a narrow band, yellowish and in general lighter, under the shoulder, visible by transparency. Some specimens have very numerous white areas and in other, reduced smaller marks that give it a reticulate aspect. Spiral lines of color never seen. There are some prominent little grooves in the base. There is not sexual dimorphism. The interior is whitish, revealing near the mouth a somewhat brownish color, interrupted by two lighter lines. The nucleus of the protoconch is white, although it is only possible to observe it in the juvenile specimens. The operculum is small and oval, extended frequently. The periostracum is fine, somewhat transparent, matt, and not rough. The animal is of reddish color to maroon with visible gray zones with magnification. Discussion:-Although included in C. decoratus Röckel, Rolán and Monteiro, 1980 by its pattern, it is evident that by its pattern, its silhouette and its radula, there would be more similarity to C. cuneolus Reeve, 1844. ---------- Conus cuvieri Crosse, 1858 Pictures: Picture Link: Lectotype in IRSN Mike Filmer Picture Link: Paul Kersten Picture Link: Paul Kersten Published in: Rev. Mag. Zool. 2, p. 123 Ocean geography: Indo-Pacific Type Locality: Swan River, Australia (erroneus) corrected to Djibouti.(C. cervus Sowerby, 1838) Type Data: Lectotype in IRSN deposited and catalogued (C.deshayesii) Type Size:51.2 x 27.4mm Nomenclature: an available name, a new replacement name (nomen novum) for C. deshayesii Reeve 1843 Taxonomy: A valid species Current Group Names:- Family:-CONIDAE SubFamily:-CONINAE Genus:-Gastridium Species:-cuvieri Synonyms:- deshayesii Reeve, 1843 Geographic Range:-S. Red Sea and Gulf of Aden Habitat:-In shallow calm water amongst fine rubble Description:-Source Living Conidae Moderately small to medium-sized, moderately light. Last whorl ovate to ventricosely conical, outline convex; left side straight or slightly concave toward base. Aperture broad at base. Shoulder angulate. Spire usually low; outline concave, often with apex projecting from an otherwise almost flat spire. Larval shell of 2-2.25 whorls, maximum diameter about 1 mm. Teleoconch sutural ramps flat to slightly concave, with 0-1 increasing to 5-6 weak spiral grooves. Last whorl with weak spiral ribs at base. Ground colour pale grey. Last whorl with olive to brown axial lines, streaks and blotches, often fusing into a broad interrupted or continuous spiral band on each side of centre. Numerous closely spaced spiral rows of irregularly alternating brown and white dots and dashes extend from base to shoulder. Larval whorls and adjacent 2.5 postnuclear sutural ramps dark brown. Later sutural ramps with light to blackish brown radial streaks. Aperture translucent. Shell Morphometry L 32-49 mm RW 0.06-0.09 g/mm (L 32-44 mm) RD 0.57-0.66 PMD 0.68-0.77 RSH 0.07-0.13 Discussion:-C. cuvieri differs from C. fragilissimus and C. obscurus by its broader last whorl (RD 0.57-0.66) and by the absence of shoulder tubercles from its early and later postnuclear whorls. The sympatric C. fragilissimus has a primarily reticulate pattern, while C. obscurus has a generally higher spire with a rather straight outline (RSH 0.11-0.16) and a cylindrical rather than ovate last whorl. ---------- Conus cuyoensis Lorenz & Barbier, 2012 Pictures: Picture Link: Holotype in MNHN Original Description Picture Link: Paul kersten Picture Link: Paul Kersten White specimen

Lond. 1854, p. 116 Ocean geography: Indo-Pacific Type Locality: West Africa (Cuming) erroneous, corrected to Keppel Bay, Queensland, Australia Type Data: Holotype in NHMUK deposited and catalogued Type Size: 27 x 15.2 mm Nomenclature: An available name Taxonomy: A valid species Current Group Names:- Family:-CONIDAE SubFamily:-CONINAE Genus:-Austroconus Species:-cyanostoma Synonyms:- coxeni Brazier, 1875; innotabilis Smith, 1892 Geographic Range:-Queensland - N New South Wales Habitat:-Typical form in shallow water to about 55 m; form innotabilis in 40-150 m Description:-Source Living Conidae Small to moderately small, light to moderately solid. Last whorl conical or ventricosely conical to broadly conical or broadly and ventricosely conical; outline convex adapically, less so below; left side slightly concave near base. Shoulder angulate, sometimes subangulate. Spire usually of moderate height, outline concave to slightly sigmoid. Larval shell of 1.75-2 whorls; maximum diameter 0.7-0.8 mm in typical form, 0.8-1.1 mm in form innotabilis. First 3-4 postnuclear whorls smooth to very weakly tuberculate in typical form, weakly to distinctly tuberculate in form innotabilis. Teleoconch sutural ramps flat, with 0-1 increasing to 3-5 spiral grooves. Last whorl with variably spaced, axially striate spiral grooves on basal third to two-thirds and with 2-3 additional grooves just below shoulder; intervening ribbons narrow toward base and at shoulder. In form innotabilis, entire last whorl with strong spiral grooves. Ground colour light bluish-grey in typical form, white to pinkish violet in form innotabilis. In typical form, last whorl without pattern or with orangish brown to brown spots and flecks forming spiral bands below shoulder, above centre and often within basal third. Spiral rows of alternating brown dots and pale grey dashes extend from base to shoulder, varying in number and prominence. Form innotabilis differs in the yellowish brown to orange colour of the pattern. Larval whorls white, sometimes grading to pale olive in typical form. Postnuclear sutural ramps with radial lines to blotches extending beyond outer margins and matching last whorl pattern in colour. In typical form, aperture violet, demarcated from the margin by a brown collabral band; form innotabilis with an orange aperture. Shell Morphometry L 17-32 mm RW 0.04-0.15 g/mm (L 17-27 mm) RD 0.66-0.74 PMD 0.79-0.89 RSH 0.15-0.22 (- form innotabilis 0.12 - 0.26 ) C. innotabilis 12 mm – 26 mm has strong spiral grooves on body whorl, white to pinkish violet and yellowish brown to orange in the pattern. Discussion:-C. cyanostoma cannot be confused with adult specimens of any of its Indo-Pacific congeners. Erosion allows no data on the apices of the 2 syntypes of C. innotabilis they otherwise match the deeper-subtidal shells of C. cyanostoma. RKK therefore apply the form name innotabilis to these shells. C. coxeni is known only by the original figure showing a shell with a straight-sided high spire (RSH ca. 0.33) and a broad last whorl (RD ca. 0.78), strongly sculptured on its basal two-thirds. The figure does not match typical C. cyanostoma nor form innotabilis satisfactorily. RKK provisionally assign C. coxeni to C. cyanostoma as a form or an aberrant specimen, although it might represent a separate species. ---------- Conus cylindraceus Broderip & Sowerby, 1830 Pictures: Picture Link: Representation of Lectotype Broderip & Sowerby (1830, Pl. 40, fig. 5) Picture Link: Paul Kersten Picture Link: Paul Kersten Published in: Zool.
