The above differences are sufficient proof for the existence of the Pacific 

 Ocean subspecies. 



H. americanus villosus (Pallas) appears as the last link in an isolated group 

 of sculpins (Hemitripteridae. Jordan, Evermann & Clark, 1930l/) possessing a 

 long dorsal, well developed head sculpture, developed flaps, etc. These characters 

 are less developed in the Atlantic species H. americanus americanus (Gmelin). 

 The most primative of the group is the Aleutian faunal representative of the 

 Bering Sea, Ulca bolini Myers . 



Family Agonidae 



50. Percis japonicus (Pallas) 



This species occurs only along the Asiatic coast in the Bering Sea to north 

 of Cape Navarin and the southern part of Anadyr Bay, without entering cold water . 



Our examples from eastern Kamchatka (Cape Africa) coast of Koriak Land 

 (Natalie Bay) and Cape Navarin; in the southern part of Anadyr Gulf (near Cape 

 Ginter). From depths 53 to 126 meters on rocky gravel and sand, usually about 

 zero degrees (0.5 to 2.6*). Our examples from 79 to 240 mm. 



51 . Hypsagonus quadricornis quadricornis (Cuvier and Valenciennes) 



Very common along Pacific coast of Asia and America, north to Bering Strait 

 (DALNEVOSTOTCHNIK, 1932, st. 26(19)). Our examples from Cape Africa, Koriak 

 Land, north part of Anadyr Gulf, (Providence Bay) and Bering Straits at depths of 

 50 to 126 meters on rocky gravel. A wide temperature range, above and below 

 zero (-1.2" to 2.8°). 



The form described by A . Y . Taranetz from the Japanese Sea as Hypsagonus 

 corniger should be considered a subspecies of the typical form. Rehndahl (Ark. f . 

 Zool. 1931, bd. 22a, no. 18, p. 52, fig. 6) has erroneously listed and figured it as 

 Percis japonicus on the basis of a photograph (fig. 6) of a specimen of Hypsagonus 

 quadricornis.

In this work the genus Ulca is erroneously placed in the Ramphocottidae; 



likewise the genus Eurymen is placed in the Liparidae.
