97. Lycogramma brunnea (Bean) 



Two examples 60 and 64 cm. long from Bering Id. (DALNEVOSTOTCHNIK, 

 St. 5; 6 miles west of Cape Ushin, Bering Id., at about 200 meters). 



98. Gymnelis viridis ( Fabricius) Plate 2, fig. 25. 



A large number of examples of this circumpolar arctic type were found in 

 the Chukchi Sea in the region of Bering Strait and Anadyr Gulf and also on the 

 coast of Koriak land (61° N) at depths of 40-70 meters. 



Head low, flat and depressed; cheeks muscular, expanded. Head length (to 

 posterior edge of gill membrane) 14.0-16 .4% TL, 1./ depth of head 6.2-7.3% L, 

 considerably smaller than width of head, which is 8.6-10. 1% L, eye small 

 2.7-4.0% L, 19.5-24.1% head, almost the same length as the snout, which is 

 3.1-4.4% L. Upper jaw different in each sex. In male extends beyond vertical 

 from posterior end of eye, 7. 1-8.4% L, 50.0-52.4% head. In females shorter, 

 about 43% of head. Bony interorbital 3.8-6.3% head. Upper lip the same height 

 throughout, solid, not attached to snout . Small distinct pores on lower jaw, edge 

 of preopercular and around eyes . Posterior portion of interorbital without pores . 

 Gill openings extend to level of middle of pectoral base . Depth of body at base 

 of anal 7.3-8.7% L . Predorsal distance not varying much as stated by N . M . 

 Knipowitch in his monograph.—' 



Dorsal fin originates over middle of pectoral fin. Predorsal 16.0-19.0% L. 

 Preanal 34.0-37.1%, pectoral oval and rounded, its length 8.0-9.9% L, 52.4- 

 64.0% head. Body naked. Lateral line on midline without curves, often quite 

 indistinct. 



Color varies greatly. Usually in life body is a yellowish green with greyish- 

 blue perpendicular bars (15-18 bars) . In one example from Bering Strait the head 

 was raspberry red. Dorsal often with 2-3 blue black ocelli, but these are absent 

 at times. Anal fin dark in males; light in females. 



In addition to G. viridis (Fabricius) among the collections from the northern 

 part of the Bering Sea, there are numbers of examples belonging to the genus 

 Gymnelis Reinhardt but represent two new species, the descriptions of which follow.

N. Knipowitch (Mem . Ak. Sci. Petersb., 22, no. 4, 1908) indicates predorsal 



of 46 examples from Barents Sea and North Polar Ocean varies between 16.2-34.8% L.
