series of close-set teeth, much smaller than iu the outer series of the 

 upper jaw. 



Ej'es large, the lower somewhat in advance of the upper, their diam- 

 eter two-sevenths of the length of the bead. 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 iu a series 

 obliquely across the cheeks. 



Gill-rakers rather slender, shorter than in the other species of this 

 genus, but similar iu form, compressed, toothed on the inner edge, 

 somewliat 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 Hippof/lossokles, thin, almost membranaceous, and somewhat 

 readily deciduous, their edges conspicuously ctenoid, but much less 

 rough than in Il.jordam. 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 Athercsthcs stumias, which this species 

 also simulates in form and color. Scales on the head entirely similar to 

 those on the botly, but somewhat smaller. Tliose on left side also 

 similar, but less strongly ctenoid. They are, however, considerably 

 rougher than on the blind side in related species. 



Lateral line very prominent, its tubes coarse. It is straight behind, 

 slightly and regularly" rising anteriorly, without trace of arch or con- 

 vexity. 



Eays of both dorsal and anal fins extensively scaly on both sides. 

 Scales extending high up on all the fins. Scales 16-71-18 (42-125-13 

 in H ippoglossoides jordani) . 



Fins low, rather fragile, the rays set well apart. 



Dorsal tin 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 

 whi(.'h is shorter than in II. jordani. 



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. 



Fin rays : D. 78 ; A. G2 ; Y. 6. 



Color i)ale olivaceous brown, rendered darker by black punctulations, 

 which form an edging around each scale, sometimes with a few very 

 faint bronze sj^ots. Fins somewhat dusky, especially the caudal and
