The dorsal fin begins at a distance from the snout equal to twice the 

 greatest depth of head, or just over the upper angle of the gill-opening. 

 The first spine is half as long as the 71st, which is the longest of all. 

 The fin is continuous with the caudal. 



The two anal spines are of nearly equal length, being about one-third 

 as long as the longest anal ray. The distance of anal from snout is 3 

 times distance of pectoral from snout. 



The caudal is developed but connate with dorsal and anal; its length 

 is contained fiom 10 times to 12^ times in total length. 



The distance of pectoral from snout is contained Ci times in total 

 length. The length of pectoral equals one-third length of head to upper 

 angle of gill opening. 



Body of the smaller type brownish yellow, top of head brown, lips 

 and forehead dotted with dark brown, branchiostegal membrane and 

 lower part of head wliitish, a brown stripe along lateral line, another 

 along the back nearer to dorsal fin than to lateral line, and a third in- 

 distinct one along anal base; vertical tins, with a dark margin, which 

 becomes -wider and involves almost the whole surface posteriorly; 

 pectoral brownish, mingled with lighter; caudal mostly dark. In the 

 larger e.vample the general color is violet brown, the dotting and stripes 

 are almost black, the dark margins of the vertical fins are absent except 

 posteriorly, and there is less whitish color on the lower parts.
