1932), south of Bering Strait and in the Chukchi Sea (KRASNOARMEIETZ, 1933) . 

 The ChukchJ examples are young from the following localities: 



1. KRASNOARMEIETZ, Aug. 16, 1933 St. 56 (54) 69" 16' N, 171" 29' W, 



depth 53 meters yellow muddy clay, temp. -1.3°, beam trawl, 2 juv. K. Paimi. 



2. KRASNOARMEIETZ, Aug. 17, 1933 St. 58 (56) 68° 42' N, 168' 13' W, 



depth 52 meters clay, temp. 1.6°, beam trawl, 1 juv. K. Panin. 



3. KRASNOARMEIETZ, Aug. 17, 1933 St. 61 (59) 67° 54' N, 168° 57' W, 



depth 57 meters muddy clay, temp. 0.8° Sigsby trawl, Ijuv. K. Panin. 



D 71-76 (79) A 54 58 Gili rakers 1-3 plus 9-12 (in 7 examples) 



Teeth on jaws small, even. Outer edge of lower jaw less arched than in H. 

 elassodon Jordan & Gilbert, therefore the tubercles do not protrude as much . 

 Interorbital wider and covered by two rows of scales which are evident in an 

 example 164 mm m length. Scales on blind side cycloid; on eyed side ctenoid. 

 Lateral Ime with a noticeable curve, forming a low arch anteriorly. It is continued 

 forward to upper eye by a pore system. Our examples 64 to 164 mm. Below are 

 measurements taken from four examples 100 to 164 mm. in total length. In 

 percentage of standard length, head 26.8-30.0, greatest depth 36.9-40 .0, in 

 percentage of head, longest diameter of upper eye 24.8-28.0, snout 16.2-18.0, 

 pectoral length 40 . -5 1 . 3 . 



Typical coloring of eyed side in young examples . Basic color light yellow 

 brown, with numerous small brown spots . In addition, along dorsal and anal fin 

 and in middle of body are large dark spots . 



We include our examples in H. robustus Gill & Townsend (=H. hamiltoni Jordan 

 & Gilbert = H. propinguus Hubbs) on the basis of the reduced fin rays and gill rakers, 

 scaley interorbital and other characters. The young differ only in color. From 

 H. elassodon from the Commander Ids. it differs as follows: 



1 . Fewer dorsal and anal rays 



2 . Fewer gill rakers 



3 . A much wider interorbital with two scale rows 



4. A grester curve in the lateral line 



5 . Much rougher ctenoid scales 



6 . Much smaller eye size (in examples of equal size) 



7. Much more elongate body 



8 . Spotty coloring of young and many otheri characters. 



in the region of Avachin Gulf, but unfortunately cannot be identified, as they are 

 not available for study. H. Rendahl (1931, no. 18, p. 65) records Hippoglossoides 

 elassodon Jordan & Gilbert from Avachin Bay. Rendahl's examples (162.5 mm) 

 approaches the typical form through the listed characters D 86, A 64, gill rakers 

 5 plus 18 (eyed side), but differs in a few measurements (eye, snout, etc.).
