FISHES FROM BERING SEA AND KAMCHATKA. 



85 



Dorsal 49; anal 36; pectoral 18; pores in lateral line 98. 



Interorbital space narrow, gently rounded; snout sharp, the jaws equal, the lips thick; mouth 

 gently oblique, the maxillary extending beyond vertical from posterior rim of orbit for a distance equal- 

 ing about half the diameter of the pupil; upper edge of maxillar>- received within a groove below the 

 preorbital, with the exception of the posterior part, which is free; symphysis of mandible with a broad 

 band of villiform teeth which is bordered in front and behind by a series of strong canine-like teeth; 

 the band rapidly narrows laterally, the anterior series disappears, and the posterior series of enlarged 

 teeth is continued laterally, at first accompanied by a single row of minute teeth, and finally alone; 

 upper jaw anteriorly with a broad band of villiform teeth, with an anterior series of well-spaced canines 

 and a few slightly enlarged teeth mesially in the posterior row; the villiform band is narrowed laterally, 

 but accompanies the series of canines throughout. Vomerine and palatine teeth in broad bands, none 

 of them specialized. 7U1 the teeth show a tendency to form one or two minute cusps midway of the 

 length, but these are never well developed. 



Pores in head numerous, small, arranged as in B. signatus. Anterior nostril in a short tube; the 

 posterior a short slit above front of eye. Gill-rakers very short, 5 above angle and 12 below on outer 

 arch, the longest when depressed covering little more than one interspace.

Scales strongly ctenoid, much rougher than in B. signalus, covering the entire body with the 

 exception of a narrow streak on median line of nape; series of smaller scales accompany basal portions 

 of dorsal, caudal, and pectoral rays, those on caudal extending beyond middle of fm; vcntrals and anal 

 scaleless. Distance of lateral line from dorsal profile less than two-fifths its distance from lower profile; 

 it ceases on middle of length of caudal peduncle. 



First two dorsal rays simple and not articulated, the succeeding rays branched finely on distal 

 fourth; anal rays similar to dorsal, but thicker, the membranes cleft, leaving the distal one-third to 

 one-half of each ray free; caudal broad and short, the margin but little convex; the first 3 ventral rays 

 profusely branched and closely connected, forming a thickened lobe in which the outlines of the spine 

 and the 3 rays are not externally apparent; the third ray is the longest, the fourth and fifth shorter, 

 distinct; lower pectoral rays thickened at tips. 



Color in life: Warm brown, the sides with irregular deep blue bars with cross-blotches of blue in 

 coarse pattern; vertical fins largely blue, the anal with brownish markings, but witliout distinct pattern. 

 No yellow or scarlet on head. In spirits, adults appear dark brown on body and fins, much darker in 

 tint than B. signatus; young specimens are pale in color, tlie sides crossed by about 10 broad dark bars 

 which extend on dorsal and anal fins; a dark blotch occurs on anterior dorsal rays in the young, but 

 this invariably disappears, while in signahis it persists in adults; in later stages the whole body becomes 

 first an olive-brown, the bars persisting longest along base of dorsal, where they appear as dark spots.
