"VII. — North American Ophiuroidea. I. — Revision of certain 

 Families and Genera of West Indian Ophiurans. II. — A 

 Faunal Catalogue of the known Species of West 

 Indian Ophiurans. By A. E. Verrill, 



Part I. Revision of certain Families and Genera of West Indian 



Ophiurans. 



The numerous shallow water Ophiurans of the West Indian 

 faunal region have been pretty fully studied by several authors,* so 

 that most of the species ai-e fairly well known, and many of them 

 are to be found in most of the larger museums. Nevertheless there 

 is no recent or fairly complete faunal list of the species. 



The deep-sea species are also very numerous. These have been 

 collected in large numbers by scientific explorations carried on by 

 the U. S. Coast Survey Steamer "Blake," under the supervision 

 of Mr. Alexander Agassiz, and by earlier explorations, under the 

 supervision of Mr. L. F. de Pourtales. A number of deep-sea species 

 were also dredged, in the same region, by the " Challenger." All 

 the U. S. Coast Survey collections and those made by the " Chal- 

 lenger" were worked up and reported upon by Mr. Theodore 

 Lyman in a number of important reports. f 



The large collections from this region made by the U. S. Fish 

 Commission steamer "Albatross" were also studied by Mr. Lyman, 

 but no report upon them has yet been published. 



During the present year the writer has published a report^ on a 

 small but interesting collection obtained by a scientific expedition to
