crossed by very narrow bars formed by series of small dark spots on the rays; usually a small dark 

 blotch on upper part of base and a larger one below; ventrals dusky in males, white in females; in 

 males, the anal is bright chrome-yellow, without bars. 



The species is represented ia the present collection by tlie type and 6 cotypes from the Okhotsk 

 Sea, to the westward of Kamchatka. It had been taken previously by the .4 Ibalross in 1S96 off Robben 

 Island in the Okhotsk Sea, and had been confused with Artediellus pacificus (Jordan and Gilbert, The 

 Fishes of Bering Sea, Report Fur-Seal Investigations, pt. 3, 1899; stations 3647 and 3648,. depth 40 

 fathoms). 



Artediellus camchaticus, new species. (Fig. 6.) 



Type, a male specimen, 117 mm. long, from station 4795, off the east coast of Kamchatka (lati- 

 tude 52° 46' 50'' N.); depth 48 to 69 fathoms. 



Larger than any species of Artediellus heretofore kno^vn, with developed nasal spine, the man- 

 dibular pores of the symphyseal pair distinct, the maxillary barbel simple, all other cephalic filaments 

 reduced or obsolete, the anal fin without crossbars, and the pores of the lateral line very numerous. 



Measurements in hundredths of length to base of caudal: Length of head 34.5; length of snout 

 10.5; length of maxillary 14; diameter of orbit 9; interorbital width 2; greatest width of head 27;

greatest depth of body 21; least depth of caudal peduncle 6; distance from tip of snout to hinder edge 

 of gill membrane on median line 19; distance from tip of snout to front of anal 54; from last anal ray 

 to last pore of lateral line 19.5; from last dorsal ray to last pore of lateral line 21.2; length of base of 

 dorsal fin 48; of anal fin 30; longest pectoral ray 26; longest ventral ray 18; longest caudal ray 22.5. 



Dorsal vm, 14; anal 13; pectoral 24; ventrals i, 3. Lateral line with 7,7, pores, including the one 

 at upper attachment of opercular membrane and the terminal pore at base of caudal. 



In 25 cotypes, the formulae are as follows: 



The pectoral rays are in equal number on the two sides in 23 of the 25 specimens examined, the 

 other 2 showing each a difference of i ray between the right and left sides. In 17 specimens, the pores 

 of lateral line are in equal number on the 2 sides, while in 8 specimens, a difference of i or 2 isfound.
