are scattered alike over the body and head and fins. 
The left side is without spots, margined at the base 
of the dorsal, aual, and caudal fins with yellow; 
this margin is wider and of a deeper tint at the pos- 
terior extremity of the body, and is continued on 
the caudal rays. Length of the head to that of the 
body without the caudal rays, as lto- 4; depth, 
including fins, equal to half the entire length of the 
fish. Mouth, small; jaws equal, with sharp teeth 
compaetly set together; /ips tumid, making the

destitute of scales; longest diameter of the eye; 
nearly equal to one fourth the length of the head. 
The lateral line commences about the length of 
the ventral fin above the pectorals, and making 2 
high arch over the pectorals, commences a straight 
course on a line opposite the twenty-fourth ray of 
the dorsal fin, and is continued to the extremity of 
the caudal rays. 
The Dorsal fin commences over the anterior third 
of the upper eye, and increasing in the length of 
its rays, which are longest towards the middle of 
the body, and again diminish in their length, ter- 
minates about an inch anterior to the rays of the 
caudal fin. 
The length of the futi one line more than
