During the summer, larvae appear to be concentrated in an area just north of the tip of the Alaska Peninsula and Unimak Island, where several catches amounted to more than 400 sand lance larvae per tow. Most of the larvae were caught in surface tows, but during the spring oblique tows seemed to catch more larvae although the catches were still not large. Sand lance are demersal spawners and no eggs were reported. Pleuronectidae The right-eyed flounders, one of the commercially important groups, are represented by 17 species in 14 genera in the Bering Sea. Larvae of this group were collected in 20 of the 26 cruises during spring, summer, and fall, most abundantly in spring. In general, fewer flounder larvae were caught in surface tows than in oblique or vertical tows. The genus Atheresthes contains two species: A. stomias, the arrowtooth flounder, generally considered an eastern Bering Sea species, and A. evermanni, the Kamchatka flounder, considered a western Bering Sea species but possibly extending to the Pribilof Islands. Since larvae of these two species have not been described adequately to permit specific identification, the records of capture are combined and presented here as distribution of the genus. Larval Atheresthes sp. were collected at 74 stations on eight cruises in spring and summer. Most of these were caught over the outer continental shelf and the continental slope but a few were taken over deep water west of the slope and from shallower water in Bristol Bay (Fig. 30-29). The distribution extended from the Aleutian Islands to 58y2°N and. from 162°W to 177°W. Individual catches of this species were small and usually consisted of only a few larvae per tow. Eggs of Atheresthes sp. are pelagic but none were reported. The genus Hippoglossoides includes H. elassodon, the f
