Chicoreus ( Siratus) ciboney (Clench & Pérez Farfante, 1945)

( Figs 3 View FIG B-D; 4C; 6A; 8A; 9E)

DESCRIPTION

C. ( S.) ciboney differs from C. ( S.) guionneti n. sp. and the other studied species in having a multispiral protoconch of three whorls ( Fig. 8A View FIG ), suggesting a planktotrophic larval development. C. ( S.) ciboney has thicker primary and secondary cords ( Fig. 3 View FIG B-D), developed but low intervarical nodules ( Fig. 6A View FIG ) which are present on the strongest secondary cords (s3, s4), shorter or absent spines in the adult morphology ( Fig. 6D View FIG ), and denticles within the outer lip. This species occurs from Cuba to Lesser Antilles in 200 to 300 meters deep.

Chicoreus ( Siratus) perelegans Vokes, 1965 ( Figs 2 View FIG A-C; 4A; 6B; 8D; 9H)

DESCRIPTION

C. ( S.) perelegans is characterized by the association of thick primary and secondary cords s3, s4 ( Fig. 2 View FIG A-C), the absence of intervarical nodules ( Fig. 6B View FIG ), short or absent spines, only two intervarical ribs, and stronger inner denticles of the outer lip than in C. ( S.) guionneti n. sp. This character association is not found in C. ( S.) guionneti n. sp. C. ( S.) perelegans is reported from Haiti to Barbados between 80 and 120 meters deep.
