550 Storer on the 
From a beautiful specimen 27 inches in length, 
brought me by Capt. Samuel Andrews, of Charles- 
town, the following description is drawn up: 
Color, olive brown ; all the upper portion of the 
body, mottled with dark brown, almost black, con- 
fluent patches; beneath, of an uniform dull olive. 
Anterior portion of the body, cylindrical; posterior, 
compressed. A slight keel upon the back. Head 
rounded, somewhat flattened on the upper portion 
in front of the eyes. Eyes, moderate in size; pupils, 
black ; irides, golden. Distance of the eyes from 
the snout, two inches. A tubular orifice is seen in 
front of, between the eyes, a line in its longest diam- 
eter. Seven large branchial apertures back of each 
eye, passing backward in nearly a straight line; 
the first, smallest. When this species is unattached, 
the mouth is a longitudinal fissure. When attached, 
it is circular, the lip forming a rng; within, fur- 
nished with hard, horny teeth, of a yellow color. 
Teeth on the roof, larger than those upon the sides 
of the mouth ; lower margin of the mouth furnished 
with a semicircular row of compact teeth; teeth 
on the lip, small ; mucous pores obvious in front of 
the eyes, passing towards the snout, and almost back 
of the eyes. Two dorsal fins; the first, commenc- 
ing back of the middle of the body, three inches 
long, nine inches high. Between this and the sec- 
ond dorsal, one inch. Second dorsal, six inches long ; 
more than an inch high, in its highest part. Anal 
fin, a mere fringe. Caudal fin, appears like the 
extremity of the solid portion of the body, very 
much compressed.
