series of close-set teeth, much smaller than in the outer series of the 
upper jaw. 
yes large, the lower somewhat in advance of the upper, their diam- 
eter two-sevenths of the length of the head. The upper eye with some 
vertical range, but not encroaching on the dorsal line. 
Interorbital space a very narrow sharp ridge, with three rows of small 
scales, a slight ridge connecting it with the lateral line. <A series of 
mucous pores around lower eye behind. About 8 scales in a series 
obliquely across the cheeks. 
Gill-rakers rather slender, shorter than in the other species of this 
genus, but similar in form, compressed, toothed on the inner edge, 
somewhat curved forwards. About 10 of them below the angle of the 
arch, the longest not one-third the diameter of the eye. 
Scales comparatively large, very much larger than in the other 
species of Hippoglossoides, thin, almost membranaceous, and somewhat 
readily deciduous, their edges conspicuously ctenoid, but much less 
rough than in H. jordani. In the latter species the scales are of much 
firmer texture, and their cilia are spine-like and stiff. The character of 
the scales is similar to that of Atheresthes stomias, which this species 
also simulates in form and color. Scales on the head entirely similar to 
those on the body, but somewhat smaller. Those on left side also 
similar, but less strongly ctenoid. They are, however, considerably 
rougher than on the blind side in related spegies. 
Lateral line very prominent, its tubes coarse. It is straight behind, 
slightly and regularly rising anteriorly, without trace of arch or con- 
vexity. 
Rays of both dorsal and anal fins extensively scaly on both sides. 
Seales extending high up on all the fins. Scales 16-71-18 (42-125-43 
in Hippoglossoides jordani). 
Fins low, rather fragile, the rays set well apart. 
Dorsal fin beginning immediately in front of the pupil, its anterior 
‘rays very low, the highest rays much behind the middle of the fin, their 
height much less than the length of the caudal peduncle, and but little 
more than the diameter of the eye. 
Anal fin similar to the dorsal, but rather higher, preceded by a spine 
which is shorter than in H. jerdani. 
Caudal fin long, somewhat pointed, the middle rays unusually pro- 
duced. 
Pectoral fins small, little more than half the length of the head, that 
of the left side less than a third. Ventral fins both lateral, small, not 
reaching to the anal spine.

Color pale olivaceous brown, rendered darker by black punctulations, 
which form an edging around each scale, sometimes with a few very 
faint bronze spots. Fins somewhat dusky, especially the caudal and
