sal and a fourth on end of caudal peduncle ; ground color unusually pale. 

 In a highly colored male the lower part of sides is blackish, provided with 

 roundish, large, white spots, the margins of which are often made con- 

 spicuous by a series of minute black specks ; fins conspicuously barred. 

 In most specimens a broad band of the light ground color crosses occipital 

 region and extends backward and downward, including margin of pre- 

 opercle above the spines and the greater portion of opercle. Arctic Ocean 

 and Bering Sea; Unalaska and Bristol Bay; taken by the Albatross at 

 depths of 5 to 30 fathoms, and taken by Mr. Scofield at Kings Island, 

 Port Clarence, and Graiitly Harbor; originally recorded from Plover Bay. 

 (Gilbert.) Here described from adult specimens 10 inches long, (verru- 

 COSU8, warty.)

Head 2f; horizontal diameter of orbit 5 in head and 1J in snout; inter- 

 orbital space 6 in head; depth 4|; maxillary reaching vertical with poste- 

 rior edge of eye, 2 in head; D. IX or X, 15 or 16; A. 11 or 12; pectoral 15 

 or 16; caudal with 9 branched rays; lateral line 40. Head wide and 

 depressed; mouth horizontal; lower jaw included; nasal spine well devel- 

 oped, but completely covered by the skin. Preopercle with a straight spine 

 at its upper angle almost covered with skin and equal in length to vertical 

 diameter of orbit; a second spine immediately below this, completely 

 covered by the skin and | as long as upper spine; at the lower angle of 

 the preopercle there is a tubercle ; opercle with a strong horizontal spine 

 at its upper angle, completely embedded in the membrane and not reach- 

 ing edge of gill flap. At the lower angle of the opercle there is a small, 

 down ward- directed spine, also completely covered by skin ; suprascapular 

 spine well developed, but completely embedded; humeral spine blunt and 

 covered; occipital ridges scarcely elevated, a slight pineal elevation; 4 

 broad, conspicuous tentacles corresponding to the positions of the supra- 

 ocular and occipital tubercles; orbital rims considerably elevated, having 

 a flat, depressed space between them; top of the head covered with small, 

 wart-like elevations. Lateral line inconspicuous, without plates, its pores 

 distant and small; above the lateral line a row of osseous plates, smaller 

 and more closely placed beneath the second dorsal ; a similar scattered 

 row below the lateral line just beneath the second dorsal; longest ray of 

 first dorsal (the fourth or fifth) 2| times in head, first 6 rays about equal 

 in length; second dorsal higher and about the same shape as the first, the 

 longest ray l/'o in head; caudal truncated, the corners about square; pec- 

 torals large and reaching to second ray of anal ; ventrals scarcely reaching 

 vent. Color above quite dark, strongly marked with black and white; a 

 saddle of black under the anterior f of first dorsal; 2 similar but smaller 

 saddle markings over the back below the second dorsal, 1 beneath the 

 anterior, the other beneath the posterior end ; a black blotch on the side
