CHLOPSIS GILBERTII. 317 
snout to vent. Snout slender, blunt, covered with papilla, soft at the end, 
ascending from the mouth forward, length from the tip to the middle of 
the eye equal to one third of that of the head. Anterior nostril above the 
premaxillary group of teeth, with a short forward directed tube; posterior 
covered by a fold of the skin which extends back to the eye giving 
the nostril the appearance of a long slit below the eye and forward opening 
in the lip. The nasal sac lies directly in front of the eye. A pair of pores 
of moderate size on the upper surface about half way between the anterior 
nostrils and the posterior. Eye large, about two fifths as long as the snout, 
nearly one ninth of the length of the head. Mouth wide, cleft extending as 
far backward as the hind edge of the orbit. A narrow notch below the 
forward nostrils between the anterior and the maxillary teeth. Teeth 
small, sharp, hooked, in villiform bands on jaws and vomer; anterior 
group forward of the lower jaws, convex forward, concave on the hinder 
margin, narrowly separated from the maxillary bands or from the vomerine 
teeth behind them; the band on the shaft of the vomer narrow forward, 
widening backward, ending at a short distance forward from the eye below 
the posterior nostrils. Gill opening small, crescentic, convex forward, 
vertical diameter nearly that of the eye, below the middle of the side ; 
interspace about one third as wide as the opening. A prominent corner on 
the angular. Lateral line distinct, above the middle of the flank, approach- 
ing the upper surface siightly forward of the dorsal. 
Dorsal origin backward of the gill openings one half of the ocular 
diameter ; fin narrow. Anal narrower than the dorsal, first ray below the 
ninety-second ray of the latter, origin at the beginning of the posterior two 
thirds of the total length of the specimen. Caudal narrow, acuminate, 
continuous with dorsal and anal. Pectorals and ventrals absent. 
Brownish flesh color, probably reddish in life, with brown puncticulations 
more or less coarse, little darker on back and head, little lighter on belly, 
fins lighter. 
Distinguished from C. equatorialis Gilb. by the origin of the dorsal almost 
directly above the bases of the pectorals, by the tail twice the length of the 
body cavity, and by the absence of a blackish streak along the median line 
of the belly. 
Specific name from that of Prof. C. H. Gilbert, who first discovered the 
genus in American waters.
