THE FISHES OP BERING SEA. 455 



Posteriorly the occiput rises and is laterally angulated, and is somewliat quadrate, there- 

 fore, in cross section. The vertex is without ridges or spines. Sujiraocular flap as long 

 as eye, lanceolate in form, coarsely fringed along the margins. A pair of broad, deeply 

 cleft flaps near middle of occiput, and a second pair at posterior edge of occiput. 

 A long nasal cirrus, a series of short filaments along margin of preopercle, one on 

 suborbital stay, one near tip of maxillary, a cleft filament near opercular angle, and 

 a series of four filaments along middle of lateral line. Anterior nostrils in a short 

 tube. Gill membranes widely joined across the throat, entirely free from isthmus. 



Lateral line rising in a high convex curve anteriorly, the curved and straight 

 portions equal. Along its course is a series of 44 plates, with the upper edge free 

 and spinous. They are large along the curved portion of the line, but diminish 

 rapidly in size posteriorly, the free edge becoming smooth or nearly so. A series of 

 much smaller but similar plates lies along base of dorsal, extending halfway along 

 back of caudal peduncle, widening under anterior half of spinous dorsal to form a 

 band which nearly fills the space between dorsal and lateral line. Skin otherwise 

 entirely naked. 



Dorsal beginning a pupil's diameter behind occiput. Spines very slender, the 

 anterior ones highest, each crowned with a membranous flap, which is digitately cleft. 

 The third spine is the longest, half length of head; the last sjiiue about two-fifths the 

 the third and one-half the succeeding short ray. Pectoral rays all simple, the lower 

 thickened with incised membranes, the longest rays reaching vertical from third anal 

 ray. Ventrals narrow, reaching front of anal when declined. Vent immediately 

 behind ventral fins, the long anal papilla reaching front of anal fin when declined. 



Color in spirits light grayish olive ; a series of five irregular quadrate blotches 

 along the back, usually connected at their lower margins. Middle of sides with dusky 

 marblings, from the lower edge of which a series of seven V-shaped black blotches 

 descend toward lower outline. The dusky marking of sides inclose small round 

 spots of ground color. An oblique dark bar on snout, and a black blotch on lower 

 portion of cheeks. Interopercle and upper branchiostegals with cross series of black 

 spots. Pectoral with a large dark blotch and indistinct crossbars on the rays. Anal 

 crossed by oblique dark bars. Caudal indistinctly crossbarred. Dorsals dusky, 

 without definite pattern. Ventrals plain.
