young (see tables) ; teeth in moderate villiform bands in jaws, the 

 outer premaxillary series not enlarged; orbit one-fourth length of 

 head, with an irregular outline; least suborbital width 2.2 in orbit; 

 distance from orbit to margin of preopercle equal to interorbital 

 width; no prominent ridges nor tubercles; interopercle widely ex- 

 posed, in no part covered by preopercle; posterior margin of an- 

 terior nostril elevated and forming a w^ell-marlced flap ; barbel shorter 

 than pupil ; branchiostegals, 7 ; gill-rakers tubercular ; gill slit before 

 first arch half length of orbit, about as wide as the slit behind the 

 fourth arch. 



Fourteen pyloric caeca about as long as the snout. 



Five scales between middle of first dorsal and lateral line, 6 below 

 origin of second dorsal (not including the lateral line scale) ; 25 

 from lateral line to origm of anal. Those along anterior portion 

 of dorsal and anal bases enlarged. Scales diamond-shaped and 

 nonimbricate, each with 10 to 16 large, suberect spinules, strongest 

 on a series of scales along the bases of the vertical fins. Lateral line 

 forming a low, convex curve anteriorly. A naked area behind pec- 

 toral, extending upwards and forwards. Eami of mandibles, the 

 gular membrane, and the anterior part of branchiostegal membranes 

 scaled; a single scale located on the branchiostegal membrane on 

 each side, opposite the upper angle of interopercle (also present in 

 the smaller specimen, 225 mm. long) ; a few extending on base of 

 second dorsal spine, surrounding the first spine; inner edge of 

 shoulder girdle completely naked. 



First dorsal spine almost concealed; the second entirely smooth, 

 slender, rounded on its anterior edge, its length 1.6 in head; last 

 three dorsal rays unbranched; base of first dorsal 1.3 in orbit, 1.6 

 in interdorsal space; height of second dorsal rays about half the 

 orbit. Longest anal rays 3.5 in head. Length of pectoral 2.25. 

 Filament of outer ventral ray reaching to fifth anal ray, the second 

 ray nearly reaching anal; ventral inserted below first dorsal base, 

 further back than usual. 



Distance from anus to base of outer ventral ray equal to orbit, 

 twice that from anus to anal; distance from ventral to isthmus 1.7 

 in head. Area between ventrals and anal naked. 



Body dark brown ; fins, belly, and lining of buccal cavity dusl^y ; 

 lining of branchial cavity black, without a light maro-in on opercular 

 membrane ; peritoneum black. 



A smaller specimen, 225 mm. long, 51 nun. to anus, from Albatross 

 station 4971, in 649 fathoms, off the east coast of central Hondo, 

 differs from the larger specimen, just described, as follows: snout 1.2 

 in orbit ; maxillary reaching to below middle of pupil ; teeth coarser ;
