than the dorsal ; length to height as 1 to 4 ; same height as 

 the dorsal fin. 



The Ventrals are directly beneath the dorsal fin, three quar-

The Anal fin is one quarter of an inch back of the ventrals ; 

 its length to its height as 2 to 3 ; color of the ventrals. 



The Caudal fin is deeply forked ; as high again as long. 



The fin rays are as follows : D. 9 ; P. 16 ; V. 8 ; A. 9 ; 

 C. 20.
