MONOLENE DUBIOSA. 22 
Vent and genital aperture on the blind side, a short distance from the edge. 
Seales small; those on the left side are ctenoid, the comb being of exceeding 
fineness; those on the right side are cycloid; and those on the head are 
smaller and extend forward to the nostrils and to the mouth. In addition 
to the scales counted on the lateral line the series contains several on the 
base of the caudal. 
Dorsal descending on the right side of the head to the origin of the fin 
near the nostrils; base terminating opposite the end of the base of the anal, 
close to the base of the caudal. Anterior rays of dorsal and anal shorter, 
protruding beyond the membrane. Anal origin slightly in advance of the 
base of the pectoral; no anal spine. Ventrals small, of six rays, that of the 
left side about one ray in advance ; a strong compressed pelvic spine. Pec- 
toral little more than half as long as the head ; no pectoral on the blind side, 
Basal portions of the fin rays scaly. 
Left side a clouded brown, darker along the lateral line; caudis ~ackish 
in the hinder two thirds; pectoral light brown at the base and black in the 
greater portion of the length with several obliquely placed more or less 
elongate spots of white; right side colorless, except where the brown pig- 
ment shows through the fins. Young specimens are much lighter and show 
a black streak along the inner ends of interneurals and interhemals. One 
at hand has small spots of darker scattered over the body; it has the hinder 
half of the caudal blackish, the anterior half of the pectoral white, and the 
posterior half of the pectoral black with a white spot in the middle. Largest 
specimen seven inches in length.

tion above the nostrils, much compressed, depth three eighths of the total 
length. Head one fourth of the entire length, without conspicuous angles. 
Snout shorter than the eye, blunt, much less prominent than that of JL ma-
