the two be different. DeKay lias well figured and described 

 the young of this species under the names fuliginosus and 

 verrucosus. 



The many specimens examined by me are from Beaufort, N. 

 C, and from Key West. 



4. CHILOMYCTERUS SPINOSUS.

 Chilomydems geomeiricus var. y, Glinther, Cat. Fish. Brit. Mus., 311, 1870 



(Brazil ; Bahia, the latter the type of C. cornutus Kaup). 



Habitat. — West Indies and coast of Brazil. 



This species, according to Glinther, differs from schoepfi only 

 in the coloration, the lines on the back being absent. Marcgrave 

 gives a figure and description which certainly refer to the same 

 fish. Artedi bases his description on Marcgrave, and this ac- 

 count in turn is the basis of the spinosus of Linnaeus. 



I have seen no specimens of this species, which would seem to 

 be a southern representative of Ch. schcepfi. Perhaps the two 

 may be color-variations of the same species, in which case the 

 name spinosus must be adopted. 



5. CHILOMYCTERUS ANTENNATUS.

Hope). Bean & Dresel, Proc. U. S. Nat. Mus., 1884, 151 (name 



only). 

 Chilomycterus pundiculatus Poey, Anal. Hist. Nat., 346, 1881 (Porto Rico). 



Habitat. — Southern seas of America. 



This species is characterized by the tentacles along the side, 

 by the coloration, and by the colorless fins. It is known to me 

 only from descriptions.
