468 THE FUR SEALS OF THE PRIBILOF ISLANDS. 



Bay, Vancouver Island; by Mr. Arthur W. Greeley in Prince William Sound, ajid by 

 Dr. Jordan at Sitka and Kadiat. Tliese specimens vary considerably in color and in 

 le^ugtli of preopercular spine. 



This species is tbe type of a distinct genus or subgenus Oxycottus, nearest allied 

 to Blennicottus, but differing in the Sharper spine of the preopercle and the lateral 

 cleft of the mouth. Oxycottus embryum is a second species of the same group, inter- 

 mediate in form and armature between Blennicottus gloMceps and Oxycottus acuticeps, 



113. Dasycottus setiger Beau. 



Taken by us off Karluk; recorded by Dr. Gilbert from various localities north 

 and south of Alaska Peninsula, by Dr. Bean from Sitkalidak, and by Mr. Starks from 

 Puget Sound. 



114. Malacocottus zonurus Bean. 



Eecorded from the Trinity Islands, and from about TJnalaska and Unimak in deep 

 water. 



115. Histiocottus bilobus (Cuvier and Valenciennes). 



This species was collected by Stejneger on Bering Island in 1897 (U.S.N.M. No. 

 48857). 



116. Blepsias cirrhosus Cuvier and Valenciennes. 



Captain Harbor, Unalaska; Petropaulski ; Iturup Island; also recorded by Dr. 

 Gilbert from Unalaska, and by Dr. Bean from Unalaska, Adakh, Kiska, and St. Paul ; 

 found by Stejneger on Bering Island. Adults from Unalaska show the following 

 color : 



Olive green, of varying shades, the belly bright coppery yellow, the cross blotches 

 on back nearly black, with paler margins ; naked patches on sides, white or brassy, 

 those on tail colored like body, those on head silvery. First dorsal light olive with 

 2 translucent patches; second dorsal mottled olive with dark spots and translucent 

 patches. Caudal with 3 blackish and 4 translucent bands. Anal yellowish olive 

 with numerous spots and translucent patches. Radiating blackish bands running 

 out from eye. The upper barbels black, the lower olive. 



117. Nautiscus pribilovius Jordan and Gilbert, new species. (Plate LXIX.) 



Nautichthys ocalofasciatus Gilbert, Report U. S. Fisli Commissioner, 1896, 434; not of Girard. 



Differing from Nautichthys oeulofasciatus in the shorter lower fins, the lower 

 cranial ridges and the coloration. 



Head, 3 to 3J; depth, 3f ; D., VIII, 23; A., 15; V., I, 3; P., 15; eye, 3^ in head; 

 maxillary, 2|; lateral line with 39 spines. 



Shape of head and body much as in N. oeulofasciatus. Head short, the snout 

 rather sharp, the anterior proiile steep; nasal spines prominent; a short ocular cirrus, 

 much smaller than in N. oeulofasciatus, shorter than pupil; interorbital space narrow, 

 about half eye, deeply concave; a blunt triangular ridge above each orbit, with a deep 

 cross furrow behind it which deepens to a pit at the vertex; nuchal ridges lower than 

 in N. oeulofasciatus, each with a coarse tubercle, lower and larger than in the other 

 species. From the nuchal depression the base of first dorsal spines rises much less 

 abruptly. Preopercle with four blunt prominences, the upper often longer and more 

 spine like. Mouth nearly horizontal, the lower jaw included; a slender filament at 

 end of maxillary; teeth small, a few on vomer and a narrow band on palatines. Gill
