| Abstract |
Heliacus (Gyriscus) worsfoldi n. sp., is described from the northwestern Bahamas. Calliostoma orion Dall, 1889, is redescribed and the radula and jaws are illustrated by SEM micrographs. C. orion lives in and feeds upon the tube sponge, Spinosella vaginalis. H. worsfoldi , the first record of the subgenus Gyriscus in the western Atlantic, is associated with a species of Zoanthus or Parazoanthus . |
