 compressed, but not muscular cheeks, small gill openings and a slight curve in the 

 lateral line, a large eye which is more than twice the snout, low anal fm, color 

 and in some other minor characteristics. It differs from G. bilabrus in the pre-

Family Lycodapodidae 



103. Ammodytes hexapterus PallasJ/ 



The sandlaunce is seldom caught by trawl as it buries in sand and gravel . 

 13 examples were taken by us near Anadyr Gulf in a dredge at a depth of 25 meters, 

 temperature 6.3° on a bottom of coarse sand, gravel and fine gravel. V. F. Shmidt 

 indicates that cod caught in the southern part of Anadyr Gulf (off Cape Gmter) 

 feed exclusively on sandlaunce. G. U. Lindberg's work on far eastern seas shows 

 our type of sandlaunce to require Pallas' name A. hexapterus . In the northern 

 Atlantic Ocean this species is replaced by a subspecies A. hexapterus marinus 

 Raitt. Our examples from Anadyr Gulf have: D 55-59, A 28-32 (in 5 ex.).
