ART. 13 REVISION OF THE COTTOID FISHES SCHMIDT 5 



Alaska, in Bristol Bay, south of Sannak Island, north of Unalaska, 

 and off St. Paul Island. According to Gilbert - it was found also 

 off Povorotnaya (Cape Povorotny on the east coast of Kamchatka) 

 in 100 and 96 fathoms, but this must be revised, as probably the 

 specimens from these localities belong to other later described species, 

 especially as Gilbert says, that " some of these specimens * * * 

 show the head with more pores than could be distinguished in the 

 type." ^ 



ARTEDIELLUS OCHOTENSIS Gilbert and Burke (1912) 

 D. VII-VIII, 12-14; A. 12-13; P. 21-23; L. kit. 27-33. 



This species is closely allied to the eastern form Ai'tediellus 

 pacificus Gilbert, but differs chiefly in having more pores in the 

 lateral line. In our large collection (71 specimen) the variation of 

 the number of pores is as follows : 



Pores 27 28 29 30 31 32 33 



Specimens 3 26 19 12 8 3 



No specimen in our collection has fewer than 27 pores, and, there- 

 fore, this species must not be regarded as a subspecies of A. pacifcus 

 Gilbert. 



Artediellus ochotensis has also well-developed and conspicuous 

 pores on the top of the head and on the occiput and many well- 

 developed cirri. There are occipital and supraorbital cirri, one 

 cirrus on the praeoperculum, one on the operculum, and a row of 

 3-5 cirri between the occiput and the third or fourth pore of the 

 lateral line. 



The coloration of this species is also very typical. On the first 

 dorsal of the male there is nearly always a round black spot on the 

 hinder edge. The dark crossbands on the dorsal, pectoral, and 

 caudal fins are very conspicuous. 



The length of the body of the full-grown specimens is 70-80 mm., 

 but some of our specimens have the length of 102.2 mm. 



Geografhical distribution. — This species is widely distributed in 

 the western part of the North Pacific. In the Bering Sea it is 

 recorded from St. Paul Bay (61° 8' N., 172° 7' E.), Archamton 

 Bay (59° 27' N., 158° T E.), Karaginskaya Guba (58° 50' N., 

 168° 13' E.), from Avatcha Bay, and from some other points of the 

 east coast of Kamchatka. In the Okhotsk Sea it is found in the 

 northern part of the sea (Tauiskaya Guba, Erineiskaya Guba, 

 Shantarsky Islands) ; on the west coast of Kamchatka (52° 38' N., 

 155° 40' E.) ; and off Sakhalin in Terpenya Bay, in Shamoff Bay, 



a Fish. Bfring Sea, 1800, p. 4o4. 



» Attention is called to the fact that Gilbert and Burke, in describing A. ochotensis, 

 expressly stated (Bull. Bur. Fish., vol. 30, 1912, p. 46) that the Robben Island, Okhotsk 

 Sea, specimens had been confused with A. paeiflcui^. — L. S.
