THE PISHES or BERING SEA. 465 



dark streaks; entire underside of head faintly dusky, mottled and. maculated with 

 white, " like a frog's belly." Iris with small, black spots and blotches. These colors 

 are fainter in our adult specimen, where the underside of the head is nearly uniform 

 whitish. The maxillary membranes are, however, conspicuously black spotted. The 

 body is brownish, with three light gray saddles, the most conspicuous of which crosses 

 the back of the caudal peduncle immediately behind the dorsal iin. The second is below 

 the dorsal notch, and the third, often obscure or wanting, forms a V-shaped area on 

 top of the head, the two arms diverging from interorbital space toward the base of 

 opercular spine. The dark areas are often lighter centrally, and are variously blotched 

 and mottled with brown or dusky. The dorsals are very irregular in the marking. 

 The aual has usually three or four oblique, dark bars. The caudal has usually a 

 basal translucent bar, followed by varying alternations of translucent and black. 

 The ventrals show two black crossbars, ^he pectorals have no definite color pattern 

 on their outer face, but are crossed on their inner face with a few irregular black bars. 

 Males show the usual round white spots on sides of abdomen. 

 Several specimens from Petropaulski and Bering Island. 



100. Myozocephalus raednius, B. A. Bean, new species. (Plate LiXlVh.) 



Head,3J; depth, 4J; eye, 4 in head, D., VIII, 17; A., 12; V., I, 3; P., 14; C, 14. 

 Profile of head and body gradually ascending from tip of snout to sixth dorsal spine, 

 thence tapering to caudal peduncle; ventral line almost straight, slightly tapering to 

 caudal peduncle; longest dorsal spine almost as long as longest ray, 3 in head includ- 

 ing flap. Mouth moderate, maxillary reaching about to vertical through middle of 

 eye. Pectorals large, reaching slightly beyond anal origin, the middle rays being 

 four-fifths as long as the head; ventrals moderately well developed, reaching anal; 

 anal origin under third ray of dorsal, ending under fourteenth ray of that fin. Gill 

 membranes united, forming a fold across the isthmus. Preocular spines moderate; 

 opercular spines but moderately developed; two flattish tubular pores, one on each 

 side of front of eye; numerous pores on head; two rows of pores, one above and one 

 below the raised ridge, running laterally on dorsal half of body. General color dark 

 reddish brown, mottled, barred, and spotted with white; under parts whitish; a wide 

 whitish bar from opercles across nape; posterior part of interorbital space whitish ; 

 the dark color on front of snout and under Jower jaw relieved by bars and mjottlings 

 of whitish; pectorals and ventrals barred; rays of caudal finely mottled ; several (5) 

 small white spots on body immediately behind pectoral origin, and several larger white 

 blotches on lower posterior half of body. Bering Sea. A single example, 2 inches 

 long. It is allied to M. stellerij from which it differs greatly in form and coloration. 

 (Type, No. 33863, U.S.N.M. Collected at Medni (Copper) Island, Bering Sea, spring 

 of 1883, by Dr. Leonhard Stejneger.) (B. A. Bean.) 



101. Myoxocephalus niger (Bean). Kalog. (Plate LXV.) 



Abundant in the rock pools of the Pribilof Islands. Recently reported by Bean and 

 Bean from Bering and Medni Islands (Nos. 33881, 38980, U.S.N.M. ; Coll. Stejneger and 

 Grebnitzki) and earlier by Dr. Bean from St.Paul and froiii Sanborn Harbor, Shumagins. 



This strongly marked species can be readily distinguished by its peculiar colora- 

 tion, by the greatly thickened naked skin, which partly conceals the short nasal and 

 opercular spines, and by the numerous tentacles surmounting the warty tubercles on 

 crown and occiput.
