seems to be still more common northward, being, in Alaska, a food-fish of 

 some importance. Abundant north and south of the Aleutian Islands and 

 in Bristol Bay. Our specimens from Kamchatka agree in all respects;

2982. HIPPOGLOSSOIDES ROBUSTUS, Gill <fc Townsend. 



Head 3f; depth 2&; eye 5| in head. D. 76; A. 60; scales 95 (pores). 

 Interorbital space a broad, somewhat elevated ridge with 2 rows of scales. 

 Body rather high, its greatest height nearly equaling | the length from 

 snout to base of caudal; profile decurved above the eye; body thick; 

 scales on head separate and rarely touch each other. Gill rakers long, 

 #+11. Maxillary 2^ in head, directed upward anteriorly; teeth of the 

 single row mostly separated from each other by intervals equal to width 

 of teeth, curved inward, and uniform on the sides ; toward front 4 or 5 

 enlarged, preceded by 2 smaller, leaving the middle toothless; in the 

 lower jaw of nearly uniform si/e and inclining backward. Pectoral i 

 head; ventrals reaching first or second anal ray. Scales on body ciliated 

 or weakly ctenoid, those on cheek smoother ; no ctenoid scales on blind 

 side. Caudal shorter than in H. hamiltoni, 1| in head. No exserted nasal 

 tubes. Color plain brown. Bering Sea. Only the type known, 12 

 inches long, from which we have taken the above description, (robustus, 

 robust.) 



ffippoglossoidet robustus, GILL & TOWNSEND, Proc. Biol. Soc. Wash., xi, 1897 (Sept. 17,

2983. HIPPOOLOSSOIDES HAMILTONI, Jordan & Gilbert, new species. 



Head 3 in length; depth 2f; longest diameter of upper eye 3 in head; 

 snout (measured from upper eye) 5 in head ; maxillary of colored side 2, 

 of blind side 2, in head; depth of caudal peduncle equaling its length, 

 3 in head. D. 72; A. 56; P. 11 ; pores in lateral line 91. Upper profile of 

 head continuing the dorsal curve without interruption, there being a slight 

 depression above the eye and an increased convexity on the snout ; man- 

 dible very heavy, projecting anteriorly, so that its symphyseal profile com- 

 pletes the curve of the snout; a very short prominence at symphysis 

 directed vertically downward; gape strongly curved and the mouth nar- 

 rowed anteriorly, so that the maxillary and premaxillary are almost 

 wholly concealed along the middle of their length by the overarching pre- 

 frontal; teeth acute, in a single series in each jaw, all except the anterior 

 teeth in each jaw short; at the symphysis of lower jaw the teeth are
