longer and directed inward, while in the anterior end of eacli premaxil- 

 lary the teeth aro still more enlarged, and the .series on each side describes 

 a strong curve with its convex side toward the median line; maxiUary 

 reaching vertical from slightly behind middle of lower eye; nostril tubes 

 conspicuous, the anterior in closest proximity to the upper lip, which it en- 

 tirely overhangs; posterior nostril tube wider and slightly shorter; eyes 

 of nearly equal size, and opposite, separated by a wider ridge than in H. 

 elassodon, the ridge bearing in its narrowest portion 2 well-defined rows 

 of strongly spinous scales; a conspicuous series of pores joining lateral 

 line with upper margin of upper eye, and another encircling the lower ej'e 

 below and behind; a third series along mandible and preojjcrcle; 1 large 

 pore above posterior nostril; gill rakers slender, unarmed, 2 above the 

 angle, 11 or 12 below it, the longest 2| in eye; dorsal lin beginning above 

 front of pupil, the longest ray 2|; in head ; anal preceded by a strong spine, 

 its height equaling that of dorsal; pectoral very long and slendei-, | length 

 of head, that of blind side shorter, I length of head; ventrals reaching 

 to base of fourth or fifth anal ray; caudal loug, evenly rounded behind, 

 the middle rays not longer than those adjacent, their length equaling dis- 

 tance from tip of snout to preopercular margin ; scales on colored side 

 strongly ctenoid except in a strip along middle of sides anteriorly; else- 

 where each scale provided with 2 to 4 long spines; on blind side they are 

 smooth except on nape and caudal peduncle; cheeks, opercles, and iuter- 

 orbital space covered with larger, rougher scales than those on sides ; man- 

 dible and snout naked; a single series surrounding each eye anteriorly, 

 and 1 on maxillary or colored side; blind side of head with maxillary 

 naked; cheeks covered with minute smooth thin scales, the opercles with 

 a few scattered spinous scales, the preopercle naked. Color nearly uniform 

 brownish, without distinctive markings on body or fins. One specimen, 

 17 cm. long, from Albatross Station 3641, otf Dalnoi Point, Kamchatka; 

 depth 16 fathoms. Allied to Hippoglossoidcs elassodon, from which it dif- 

 fers in the fewer fin rays and scales, the wider interorbital space, the 

 bmger caudal and pectoral fins and the much smaller symjihyseal knob. 

 The nasal tubes aro larger, the scales rougher, and the anterior part of 

 lateral line more arched. Its relations with H. robustits are much ntsarer 

 but the species are apparently distinct. (Named for Gerald Edwin H. 

 Barrett-Hamilton, of Dublin, member of the British Commission of Fur 

 Seal Investigation, 1896 and 1897, who made valuable collections of Kam- 

 chatkan fishes.)
