THE FISHES OF BERING SEA. 491 



the lateral line descends iu a gentle curve to middle of sides. The scales are very 

 rough, each possessiug several loug, sharp spines diverging from median jjortion of 

 posterior margin. Anterior and posterior portions of dorsal and anal fins naked, the 

 rays of the middle portion each with a series of strongly ctenoid scales. Caudal 

 densely scaled to tip. Pectorals and ventrals naked. Head covered with strongly 

 spinous scales, excepting snout, maxillary, and mandible. On blind side of head the 

 snout, .laws, preopercle, subopercle, lower half of opercle, and all but a cejitral strip 

 on iuteropercle, scaleless. On blind side the scales are rough on head, ventral area, 

 and along bases of ventral fins ; largely smooth elsewhere. 



Dorsal beginning above front of pupil, the rays increasing in length to the forty- 

 fifth, which is 2| in head. Longest anal ray (the seventeenth), 2f in head. Caudal 

 broadly rounded, 1| in head. Pectoral short and broad, 2f in head. Ventrals of 

 nearly equal length, reaching origin of anal, 3| in head. No anal spine. 



Color in spirits : Centers of the scales light gray, the margins dark brown. Fins 

 light or dusky, the vertical fins with conspicuous black bars i^arallel with the rays. 

 These are most evident on the under side, where the pigment seems to principally 

 occur, and are seen through the fin more faintly on the colored side. Lining of cheeks 

 and gill cover of colored side dusky. Peritoneum gray. The species is named for 

 Jefferson P. Moser, TJ.S.N., commander of the Albatross. 



Verasper variegatus (Schlegel), of the same genus, is closely related to V. moser i, 

 from which it differs chiefly iu the much lower and smaller arch of the lateral line. 

 The fins in this si)ecies are spotted with black, but not barred. 



221. Lepidopsetta bilineata (Ayres). 



Abundant everywhere in Bering Sea. Our specimens from St. Paul Island; 

 station 3637, off St. George, 32 fathoms; Unalaska; Bering Island; Medni Island. Dr. 

 Gilbert records the si)ecies from Unalaska, Herendeen Bay, Hagemeister Island, and 

 from various localities about the peninsula of Alaska. 



222. Litnanda aspera (Pallas). 



Common; taken by us at Petropaulski, Avatcha Bay, Kamchatka; stations 3646 

 and 3647, oft" Eobben Eeef, in 18 and 20 fathoms. Eecorded by Dr. Gilbert from Bristol 

 Bay, Herendeen Bay, and many other stations. Dr. Bean mentions it from Sitka, 

 Kadiak, Shumagins, Port Clarence, Plover Bay, and Indian Point. 



223. Iiimanda proboscidea Gilbert. 



Described from Bristol Bay and Herendeen Bay. 



224. Pleurouectes quadrltuberculatus (Pallas). 



Station 3642, Avatcha Bay, 16 fathoms. Station 3647, off Robben Eeef, 20 fath- 

 oms. Eecorded by Dr. Gilbert from Chernofski Harbor, Herendeen Bay, and Bristol 

 Bay, by Dr. Bean from Kadiak, and by Mr. Scofield from Chigink and Port Clarence. 



This species is a true Pleurouectes, having the lower ijharyngeals narrow, separate, 

 with two rows of bluutish teeth. It is an ally of Pleurouectes platessa. 



225. Liopsetta glacialis (Pallas). 



Petropaulski. Eecorded by Dr. Gilbert from Bristol Bay, by Dr. Bean from 

 Kotzebue Sound, and by Mr. Scofield from Port Clarence.
