" The ventrals originate under the sixth or seventh dorsal ray, but 

 the structure and form of all the fins are nearly as in C. Luddus. 

 The adipose is not supported by interspinous bones, but it exhibits in 

 the dried specimen a very fine, apparently fibrous structure, which en- 

 tirely disappears when the fin is moistened. In one specimen the 

 centre between the tip of the snout and end of scales on the caudal, 

 corresponds with the first ray of the ventrals and thirtieth scale of the 

 lateral line ; in another it is a little posterior to the first ventral ray, 

 being at the thirty-third scale of the lateral line : in the last specimen 

 the lateral line has seven scales more than the other."
