NO. 1924. NEW PHILirriXE AXACANTHINE FISHES— RADCLIFFE. 127 



small, inner rays not reaching base of anal, outer ray filamnetous, 

 2.20 in head; pectoral 1.94. 



Color in alcohol: Light brown; belly and opercular region blackish; 

 fins dusky. 



Type.— Cat. No. 72943, U.S.N.M., 23 cm. in length, taken with a 

 beam trawl at station 5654 (lat. 3° 42' 00" S. ; long. 120° 45' 50" E.), 

 Gulf of Boni, Celebes, at a depth of 805 fathoms. 



This species is readily distinguished from nigrescens by the arma- 

 ture of the scales, the less angular form of the snout, the fewer ventral 

 rays, and the fewer, more widely separated spinules on the second 

 spine of first dorsal. 



Genus CCELORHYNCHUS Giorna. 



CCELORHYNCHUS MACRORHYNCHUS Smith and Radclifie, new species. 

 Plate 29, fig. 1. 



Dorsal ii,8-67; anal 76; ventrals 7; pectorals 18. 



Head 3.10 in total length, very long, strongly depressed ante- 

 riorly, greatest breadth nearly equaling greatest depth, subquad- 

 rangular in transverse section, lateral contour of head forming nearly 

 a straight line; suborbital ridge strongly saHent, encUng abruptly at 

 a distance nearly equal to diameter of pupil from angle of preopercle; 

 the two ridges on each side of nape well developed, converging and 

 meeting over anterior margin of eye; body robust, greatest breadth 

 about 0.66 its depth, the latter 6.44 in total length; vent slightly 

 less than half an eye diameter in front of origin of anal; tail com- 

 pressed, tapering (tip mutilated, rays of tip well developed); e3"e 

 subeUiptical, horizontal diameter 5.48 in head, shghtly more than 

 0.66 length of snout, vertical diameter 0.66 horizontal diameter; 

 interorbital broad, flat, equal to horizontal diameter of eye; snout 

 2.15, outhnes long, narrow, scarcely at all convex, converging regu- 

 larly from base to tip, depressed, upper surface everywhere trans- 

 versely convex, longitudinally shghtly concave; width of snout 

 opposite anterior margin of eye 1.73 in its length; anterior nostril 

 small, subeUiptical, about 0.4 vertical length of the posterior; mouth 

 relatively large, its anterior margin slighth" in front of nostrils; 

 maxillary 3.48, nearly reaching vertical from posterior margin of 

 orbit; mandibular barbel long, slender, about 0.87 horizontal diam- 

 eter of e\^e; teeth slender, cardiform, those along outer margin of 

 upper jaw very slightly enlarged; scales large, imbricate, 6 in a series 

 from origin of dorsal to and including lateral line, the same number in 

 a series from last dorsal ray to and including lateral line; scales on 

 body armed vnih about 7 radiating subequal spinous ridges, posterior 

 spines projecting but little beyond margin of scales; scales of the 

 median dorsal line of snout, those between the two lateral ridges on 

 each side of nape, on opercle and distal portion of preopercle, and
