has already been given. The teeth, of small size, are crowded into 
narrow bands on the jaws. 
The fins are essentially like those of the other forms, the chief 
difference being in the number of ventral rays, which is 8 (7 in 
torvus); 127 fins were counted, of which 125 had 8 rays; the two 
fishes with 7 rays in one ventral had 8 rays in the other. The lengths 
of the various fins, when entire, are given in the table of proportional 
measurements. The base of the pectoral les between the verticals 
from the origin of the dorsal and the base of the ventral. 
Coloration in alcohol: brown on the trunk, becoming much darker 
near the front of the first dorsal fin and near the occiput; the tail is 
light yellowish, with traces of a median silvery streak; the middle 
of the sides of the trunk is silvery; the belly is underlain with darker,

but superficially is silvery behind the ventrals and coppery before 
them. The region of the belly, extensively striated, is separated from 
the sides by a dark line, which extends from the blackish streak at 
the pectoral base to the anus; this dark line hes over the postclavicle. 
Below this streak the skin becomes more leathery than elsewhere, and 
is marked by a pattern of “striae,” consisting of fine parallel and 
alternating lines of purplish black and silvery color connected with 
structural modifications. The lines are vertical (or transverse be- 
low) along the sides of the isthmus and backward to the ventrals and 
thence upward on the face of the shoulder girdle to before the pectoral 
fins, and backward almost to the anus. The striae in a small patch 
inward and forward from the ventrals are irregularly arranged, 
like the papillary ridges on one’s fingers. Toward the mid-ventral 
line behind the ventral fins the striae become longitudinal. A 
squarish region before the ventrals, the center of which is located at 
the anterior lens-shaped organ, is devoid of striae. The gular mem-
