THE FISHES OF BERING SEA. 467 



peduncle being contained about 3^ times in greatest depth of body. The long diameter 

 of the eye equals the length of the mandible, almost that of the maxilla, and is contained 

 3^ times in the extreme length of the head. Interorbital space narrow, its width one- 

 half length of eye. Gill membranes united and forming a fold across the isthmus. 

 Opercular spines well developed, the lowermost on opercle and that on preopercle 

 being curved downward and forward. Cranial ridges ending in spines of small size. 

 Numerous pores on head, those in front visible to the naked eye; tubular ijores on 

 body, especially above anal base, where they appear to the naked eye as raised white 

 specks. 



Fins all well developed, large; length of first dorsal base little more than one-half 

 length of second; anal fin beginning under third and fourth rays of second dorsal and 

 ending opposite its last ray; length of longest dorsal spine about three-fourths as long 

 as longest ray, or equal to length of longest anal ray; pectorals large and broad; 

 ventrals reaching past anal origin. 



Color reddish brown, relieved by much white; under parts whitish; head above 

 and below brown, flecked with white; lips pale; a broad white half bar on body 

 extending from end of spinous dorsal to fourth ray of second dorsal, another extending 

 from sixth to ninth ray, and a third ffom last ray to near end of caudal peduncle, 

 which it encircles in connection with a dark bar, the latter extending on the caudal 

 fin; pectorals and caudal barred; ventrals with round black blotches forming 

 rows on the rays. Bering Island; only the type known. (B. A. Bean.) (Type, 

 No. 33875, U.S.N.M., a single example 3 inches long, Bering Island, 1883; collected 

 by Dr. L. Stejneger.) 



107. Megalocottus laticeps (Gilbert). 



Eecorded from the neighborhood of Bristol Bay. Mr. Scofield found it at Port 

 Clarence. 



108. Megalocottus platycephalus (Pallas). (Cottus twniopterus Kner.) 



Eecorded from Kamchatka by Pallas, and from Decastris Bay, near the mouth of 

 the Amur Elver by Kner. 



109. Oncocottus hexacornis (Richardson). (Plate LXVIII.) 



Northern part of Bering Sea and northward through the Arctic to Greenland. 

 Very doubtfully distinct from Oncocottus quadricornis of Europe. Eecorded by Mr. 

 Scofield from Herschel Island and Grantley Harbor, and from Bering Island by Dr. 

 Stejneger. 



110. Zesticelus profundorum (Gilbert). 



Originally described from three specimens fi'om Bering Sea. A fourth specimen 

 dredged by us off Bogoslof Island, a little larger than the types, has D., VI, 10; A., 

 8; P., 20. One of the original types has D., VII, 12; A., 10; P., 20; but in all other 

 respects the two specimens agree absolutely and th*ey are no doubt identical. 



111. Blennicottus globiceps (Girard). 



Eecorded by Dr. Bean from Kadiak, Adakh, and Amchitka. These records need 

 verification, as perhaps some other species was mistaken for it. 



112. Oxycottus acuticeps (Gilbert). 



Originally described from Unalaska; found later by Dr. Gilbert at Departure
