Teeth molariform or sharp, but not serrate; better developed on blind side . 

 LI with a high arch with some 22-25 pores. Head length in examples 131 to 165 mm. 

 is 25.2-25.4% SL. Gill rcikers short and fat not covered by spines. The color is 

 conspicuous which consists of narrow black lines, crossing the body at the base of 

 the unpaired fins . The lines are distinct in live examples but fade in alcohol. 

 Unpaired fins yellow on blind side . In spring they are dark on the eyed side 

 with light edges. 



71 . Limanda proboscidea Gilbert 



In three years' investigations in the bermg Sea, this species was found only 

 once: DALNEVOSTOTCHNIK, Aug. 21, 1932, st. 42 (35), 62° 48' N, 168° 30' W, 60 

 miles NW of Cape Romanof (America) near the mouth of the Yukon, 20 meters 

 depth on sand, bottom temperature 9.5°, otter trawl, 1 example, A. Andriashev. 



The snout very long, blind side yellow, not in two yellow bars as in the 

 related Limanda punctatissima Steindachner from the Japan Sea . 



The find of this form at the mouth of the Yukon forms the northernmost 

 record for the species.

A flatfish having four tubercles is common throughout the entire Bering Sea . 

 Nortli. to Providence Bay?', common in Anadyr Gulf, but most (commercial) banks 

 are much further south (Avacha Bay), where an otter trawl took 300 examples of 

 big and fat flatfish. Usually found on sandy bottoms, single examples on rocky 

 gravel facies (Anadyr Gulf, Providence Bay, Cape Ginther and Cape Navarm). 

 Bathymetric range wide (20 to 150 meters) but unusual quantities of four tabercled 

 flatfish were found in early June (DALNEVOSTOTCHNIK, st. 1 off Cape Piramiduogc, 

 south of Avachin Bay) at depths of 100 meters (300 examples), in the same region 

 their numbers diminished (to about 40 examples) at greater depths (150 meters). 



i/ 



The so-called four tubercled flatfish usually has 5 tubercles on the preorbital- 

 Single examples have been found with 6 and 7 tubercles. 



2/ 



On the American coast to Bering Strait.
