OPHICHTHYS (CRYPTOPTERUS) FRONTALIS. 309 
Mouth wide, cleft to a vertical from the hinder border of the pupil. Teeth 
small, subconical, subequal, in bands on jaws and yomer; vomerine band 
narrowing backward and ending at a vertical from the front edge of the 
eye; the group at the head of the vomer not separated from the band on 
the shaft or from the bands on the jaws. Gill openings hardly equal to the 
length of the eye, separated on the chest by a space greater than their 
width, extending upward over less than half of the pectoral base. Mucous 
cavities of the head greatly developed ; pores larger and elongate on the | 
forward portion of the snout. 
Dorsal and anal of medium development, continuous with the caudal. 
Dorsal origin the length of the mouth backward from the bases of the 
pectorals. Anal origin distant from the end of the snout two and one third 
times the length of the head, below the fifty-fourth ray of the dorsal. 
Caudal short, narrow, pointed, Pectorals short, as long as the mouth, com- 
paratively deep, broadly rounded, reaching when applied to the side of the 
head one third of the distance to the middle of the eye or one fourth of 
that to the end of the snout. 
Lateral line distinct, somewhat arched above the gills. Vent below the 
fifty-third ray of the dorsal. 
Total length ten and one half inches. 
Blackish above the lateral line ; dark chocolate brown below, excepting 
on the lower surface of the head, the lateral line, and the bases of the fins, 
which are white. Dorsal and anal are yellowish white in their proximal 
halves, black in the distal portions, and each pectoral has a large blotch of 
black on the upper and hinder portion of the fin. The linings of the gill 
chamber are black, of the mouth white, and of the abdomen silvery. 
Specific name from that of Prof. B. W. Evermann of the United States 
Fish Commission.
