*Hypoglossum Inyolyens (Harveyl J. AgardlL. Found twice on

 algae (Digenia , Sargassum , Halimeda , Laurencia ) , on 

 limestone on the algal plain in 15 to 23 m depth, and on hard 

 surfaces in protected places on the reef. Previously re- 

 corded from shallow water to 15 m depth (Taylor, 1960) . 

 Randall (1964) found this species in the stomach contents of 

 the queen conch, S trombus gigas , and recorded it from the
