FISHES FROM BERING SEA AND KAMCHATKA.

Dorsals usually closely contiguous in males, more widely separated in females; spinous dorsal less 

 elevated in males than in other species, and the membrane less deeply incised, the first 4 spines only 

 having the tips well exserted. All the dorsal rays and a few of the posterior anal rays are branched 

 toward their tips; the upper 9 pectoral rays are branched and are longer than any of the simple rays, 

 which are rapidly shortened downward and forward; ventral rays all simple. 



Lateral line with a single series of small pores along its lower edge, terminating in a much larger 

 pore at base of caudal. 



Color in spirits: Grayish, coarsely mottled and blotched above with brownish, the occiput and 

 sides of head often with darker blotches; the dark markings may be intensified under spinous dorsal, 

 under soft dorsal, and on caudal peduncle to form faint bars; often a very few conspicuous irregular 

 blotches below lateral line. Anal fin unmarked in males as in females; spinous dorsal with black margin 

 and a roundish black blotch faintly ocellated with lighter on distal half of posterior rays; soft dorsal with 

 about 5 oblique dark bars; caudal with 4 crossbars not so wide as the light ground; in males the upper 

 part of pectoral light, with faint narrow crossbars, the distal part of all the simple rays black, with a 

 narrow white margin; in females tlie upper part of pectorals more distinctly crossbarred, the lower 

 portion white; ventrals white in females, slightly dusky in males. 



The species is known from the t>-pe and 8 cot>'pes from stations 4794 and 4795 and from numerous 

 specimens from station 5025, as below:

Tiiglops beani Gilbert. 



List of Stations. 



These specimens, taken off Petropavlovsk, are somewhat duller in color than in specimens from 

 eastern Bering Sea, and have the lateral black stripe of the male more interrupted and broken. The 

 eye averages a trifle smaller and the caudal peduncle more slender. These differences would doubtless 

 disappear in a large series of specimens. 



Triglops scepficus Gilbert. 



Known hitherto from the vicinity of Unalaska and the region south of the Alaska Peninsula; 

 here recorded to the westward from near Attn and tlie Commander Islands.
