Recorded from Sakhalin by Tilesius; not seen by recent writers. 



121. Brachyopsis rostratus (Tilesius). (Plate LXX.) 



Several specimens from Shana Bay, Iturup Island, show the following characters : 

 Dorsal face wider than in Occa dodecaedron or in Pallasina barbata and deeply con- 

 cave; snout elongate, depressed, its width taken at middle of its length one-half 

 greater than its depth at the same point, and one-half its length, measured from tip of 

 lower jaw^ lower jaw much longer than upper, the symphysis entering upper profile of 

 snout, vertically furrowed at tip; maxillary not reaching orbit, 4 in head; preorbital 

 elongate, with a lengthwise ridge which divides anteriorly, the branches not termi- 

 nating in spines ; the edge of preorbital entire ; anterior nostril in a short tube. Teeth 

 all minute, present on jaws and vomer, often absent on palatines, sometimes present 

 in a small patch on extreme anterior end. Suborbital stay without spine, forming a 

 gibbons striated protuberance on middle of cheek, between which and the horizontal 

 edge of preopercle is a series of three or four small plates; two strong diverging spines 

 at angle of preopercle; a shorter spine below them ; orbital margins elevated superiorly 

 and posteriorly; interorbital space very narrow, grooved, and longitudinally striated, 

 its width equaling one-half diameter of orbit, which is 6 in head; no spines on top of 

 head, the ridges low and rounded. Head 4| to 4| in length; width of body 8^ to 8J; 

 length of caudal peduncle 3J to 4. 



Body anteriorly hexagonal, the upper lateral ridge becoming obsolete immediately 

 in front of spinous dorsal; lower lateral ridge also becoming rounded and obsolescent 

 anteriorly; dorsal face widening rapidly from occiput to front of spinous dorsal where 

 its width equals snout; it gradually narrows posteriorly, the dorsal ridges becoming 

 confluent at a point much nearer base of caudal than end of second dorsal; ventral 

 ridges spineless, the lateral ridges with short spinous points, often distinguishable 

 with difficulty ; dorsal series anteriorly with stronger spines which rapidly diminish 

 posteriorly; branchiostegal and gular membranes without plates; plates on body with- 

 out the minute prickles so characteristic of Occa verrucosa and 0. dodecaedron; breast 

 covered with polygonal plates, a series elevated to form a median ridge, the marginal 

 plates also prominent; prepectoral area wide, with four prominent plates, the upper- 

 most bearing a short spine posteriorly; in the dorsal series of plates, 10 lie in advance 

 of first dorsal, 11 between origins of first and second dorsals, 9 or 10 along base of 

 second dorsal, 6 to 9 between second dorsal and the point of confluence of the dorsal 

 series, and 5 to 7 between the latter point and base of caudal; total number of plates 

 in dorsal series 43 to 45, in 6 specimens examined. 



Pectorals long and narrow, 1 J in head ; dorsal with 8 (rarely 9) spines and 8 soft rays ; 

 anal with 13 (rarely 14) rays; pectoral with 14 rays. Color dusky above, marked with 

 small black spots and lines; white below, growing dusky posteriorly; caudal blackish; 

 ventrals white, anal white, with the last rays dusky; dorsals and pectorals with the 

 rays finely dotted with black.

122. Pallasina barbata (Steindachner). 



Tyro specimens from Shana Bay, Iturup Island, one from Tareinsky Bay, Kam- 

 chatka. Recorded by Dr. Gilbert from Bristol Bay, and by Dr. Bean from Yakutat, 

 TJnalaska, and Port Clarence. Mr. Scofield found it at Port Clarence and Stejneger 

 at Petropaulski. They show the typical arrangement of plates on the breast, the
