fig. 10) can be considered nothing but a large, thin variety of 

 this species. Trophon cepula Sowb. (Thes. Conch., IV, p. 

 61, pi. 404, fig. 14; pi. 405, fig. 27) is also a synonym. 



Trophon craticulatus Fabricius.

Trophon Siuarti E. A. Smith (Proc. Zool. Soc, p. 481, 

 pi. 48, fig. 6, 1880), seems to me to be simply a well developed 

 form of this species. I can see no distinctive characters by 

 which the two species may be separated. 



Genus Ocinebra Leach. 



The following sections are probably synonymous with 

 Ocinebra: Heteropurjpura Bayle 1880 (type 0. polymorpha 

 Broc.) and Hadriana Buc. et Dantz. 1882 (type O. craticu- 

 lata Broc). 



Subgenus Favartia Fischer. 



Ocinebra cellulosa Conrad. 



Murex cellulosa Conrad, Proc. Phil. Acad. Scl., Ill, p. 26, 1846. 



Besides Murex nuceus Morch, the following species are 

 undoubtedly synonymous with cellulosa: casta A. Adams, 

 Jamaicensis Sowb., tetragonus Brod., and cyclostoma Sowb. 

 Dr. Wm. H. Dall has characterized a variety distinguished by 

 being somewhat smaller and more slender, with one varex less 

 and the varices thinner and branched, each branch having a 

 sharp edge. The species is found plentifully throughout the 

 West Indies and southeastern part of the United States. 



Subgenus Pterohytis Conrad, 1862.* 



Ocinebra Cai.ifornica Hinds. 



Murex Calif ommis Hinds, Zool. Proc, London, p. 128, 1843; Voyage 

 Sulphur, pi. iii, fig. 9, 10. 



I have seen no good description of this species, and as it is 

 very frequently mixed with other species, a description
