( S. ) ciboney differs from C. ( S. ) guionneti n. sp. and the other studied species in having a multispiral protoconch of three whorls ( Fig. 8A ), suggesting a planktotrophic larval development. C. ( S. ) ciboney has thicker primary and secondary cords ( Fig. 3 B-D), developed but low intervarical nodules ( Fig. 6A ) which are present on the strongest secondary cords (s3, s4), shorter or absent spines in the adult morphology ( Fig. 6D ), 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 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 A-C), the absence of intervarical nodules ( Fig. 6B ), 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.
