226 DEEP SEA FISHES. 



the spots are ocellate and probably were bluish in life. On the lateral line 

 there are one to three ill-defined large blotches of dark brown, one near 

 the middle and another near each end of the straight portion of the line. 

 There are three parallel series of small oblong spots of blue in front of the 

 interorbital space from the snout to the space in front of the upper eye. 



On a specimen from Acapulco the three spots on the lateral line are 

 partly divided so as to form three pairs; there are brown spots at each side 

 of the median series, and five rather indefinite spots on the hinder halves 

 of dorsal and anal.

Re.sting on the right side, moderately elongate, three elevenths as deep 

 as long, much compressed. Head less than one fourth of the total length, 

 angular at the snout and behind the lower jaws, and indented above the 

 nostrils. Snout two thirds as long as the eye, with a prominence above the 

 end of the maxilla and another sharper one below the symphysis of 

 the lower jaws. Eye large, two sevenths of the length of the head and one 

 and one half times that of the snout; lower eye but little farther forward. 

 Interorbital space very narrow, traversed by a sharp ridge which curves up- 

 ward behind the upper eye and downward in front of the lower. Mouth of 

 medium size, asymmetrical, curved; maxilla widened backward, rounded on 

 the corners. Teeth small, subequal, little larger forward. Gill rakers short, 

 strong; five to six shorter ones on the upper section of the first arch, and 

 six to seven larger, plus four or five rudiments, on the lower. Edge of pre- 

 operculum free. The height of the curve in the lateral line is about half of 

 the length of the eye ; its length is about two and one half times its height 

 at the forward end ; siiperiorly the curve is much depressed and posteriorly 

 it is longer and descends to the middle of the side. Nostrils small, clo.'^e 

 together ; posterior on the left side small, pore-like, anterior with an acute 

 angled flap or valve which is prolonged in a short filament; tho.se on the 

 right, the blind side, very small, hardly to be distinguished from the pores.
