I had overlooked Cameron's description of this species. I 

 do not think that there are sufficient reasons for separating 

 the genus from Calyoza. Enderlein seems also to have 

 overlooked Cameron's paper. 



XXXIV. — On the Pacific Species of Hippoglossoides. By 

 Peter Schmidt, Curator of the Ichthyological Department 

 of the Zoological Museum of the Imperial Academy of 

 Sciences in Petrograd. 



The genus Hippoglossoides, Gottsche [Drepanopsetta, Gill), 

 is represented in the Atlantic Ocean, as has been shown by 

 Collett (1878) and by Smitt (1893), by only one species— 

 Hippoglossoides plalessoides, Fabricius. The identity of 

 American and European representatives of this species, 

 formerly distinguished as Hippogloss rides platessoides and 

 H. limandoides, is now conceded apparently by all European 

 and American writers. 



Very different at first sight are the conditions in the 

 Pacific, where no less than five reputed species of Hippo- 

 glossoides are recognized : — 



(1) Hippoglossoides elassodon, Jordan & Gilbert (1SS0), 



described from Seattle, Tacoma, and Puget Sound, 

 and afterwards recorded from the Bering Sea by 

 American naturalists, and by me from the Okhotsk 

 Sea (Schmidt, 1904). 



(2) Hippoglossoides robustus, Gill & Townsend (1897), 



described from one specimen only from the Bering 

 Sea (lat. 56° 14/ N., long. 164° 08' W., 49 fath.). 

 Not found afterwards. 



(3) Hippoglossoides hamiltoni, Jordan & Gilbert (1899), 



described from a specimen from Avatcha Bay. I 

 recorded two examples from the Okhotsk Sea near 

 Cape Terpeniya (Schmidt, 1904). 



(4) Hippoglossoides dubius, Schmidt (1904), described 



from two specimens (one of them young) from the
