FISHERY BULLETIN OF THE FISH AND WILDLIFE SERVICE 



Ctenostomata: only 5 species within the Gulf 

 and 8 more in the West Indian area, but the only 

 references to this group are those of Osburn, 1914, 

 from the Tortugas, and 1940, from Puerto Rico. 



Cheilostomata: about 155 species within the 

 Gulf with many more from around the West In- 

 dian Islands and the Caribbean Sea. 



Very little of the great area of the Gulf has 

 been explored biologically, and our knowledge 

 of the faima is limited almost entirely to that of 

 the coastal shelf reaching from the Straits of 

 Florida to the Mississippi Delta. Here the 

 dredgmgs have practically all been above the 

 100-fathom line. Intensive collection has been 

 done in only a few places; for the Bryozoa, only 

 around the Tortugas Islands . In all of the western 

 part of the Gidf and around to Yucatdn even the 

 shallow waters are untouched, the deeper waters 

 are also unknown territory, and careful collecting 

 from the shore lines to the abyssal regions will 

 undoubtedly yield a wealth of information.
