FISHES FROM BERING SEA AND KAMCHATKA. 



61 



Zesticelus proftindorum (Gilbert). 



One specimen from station 4781, between Petrel Bank and Agattu Island; depth, 482 fathoms. 



Dorsal v-12; anal 10; pectoral 20; pores in lateral line 17. Upper preopercular spine reaching 

 margin of opercular flap. Lateral line with two series of pores anteriorly. In this specimen there are 

 3 ventral rays on one side, 2 on the other. 



Malacocottus zoniirus Bean. 



In a specimen 12 cm. long, the stellate granulations are distributed over the top and sides of the 

 head and extend in a band along the back and well up on the soft dorsal. 



List op Stations. 



This extends the known range of the species to Attu Island, the westernmost of the Aleutian chain . 



Gymnocanthus pistilliger (Pallas). 



Avatcha Bay, Kamchatka. 



As has been previously noted (Jordan and Gilbert, Fishes of Bering Sea, Report of Fur-Seal Inves- 

 tigations, pt. 3, 1899, p. 460), typical representatives of this species differ from those obtained from 

 eastern Bering Sea in several respects. The top of the head is more largely covered with rough plates, 

 which always invest the occiput and usually cover a part of tlie interorbital space; in many specimens 

 from eastern Bering Sea the top of head is bare, or with only two or three scattered plates; in several 

 the occiput is largely covered, but in only one are there any plates on intcorbital space. 



Among the specimens recently acquired from Kamchatka is one adult male, in which the ventral 

 rays are greatly produced, though less so than in eastern specimens, and the spinous dorsal and the 

 abdomen have much less dark pigment in the areas around the spots. 



The fin rays of the new Kamchatkan material are as follows: 



Lateral line with 39 pores to base of caudal. 



Both lots of Kamchatkan specimens have more frequently 17 anal rays, while 16 is the most common 

 in eastern specimens. We do not venture at present to distinguish these two forms. 



Gymnocanthus detrisus, new species. (Fig. 13.) 



Type, a female 175 mm. long, from station 4798, off the west coiistof Kamchatka; depth 25 fathoms. 



Measurements in hundredths of total length without caudal: Head 36; diameter of orbit 9; least 

 interorbital width 5; width across supraorbital tubercles 9; distance between anterior ends of occipital 

 ridges 7; between posterior ends 6; length of snout 10; of maxillary 14; length of upper preopercular 

 spine 7; greatest width of head 21; depth of body 20; depth of caudal peduncle 4.5; longest dorsa] 

 spine 16; longest dorsal ray 15; interspace between dorsals from tip of last spine to base of first ray i; 

 longest caudal ray 19.5; longest pectoral ray 26; longest ventral ray 18.
