8 PROCEEDINGS OF THE JTATIONAL MUSEUM vol.71 



One specimen in our new collection (No. 21298, length of the body 

 46.5 mm.) has also a milk-white spot on the nose. 



Geographical distribution. — According to the collection of the 

 Zoological Museum, this species is largely distributed in the Arctic 

 Ocean near the Siberian coasts from 44° E. to 173° 24' W. (near 

 Bering Strait) and was found in Barents Sea in 79° 45' N., in 

 Kara Sea in 76° 59' 30" N., and in Nordenskjold Sea (Siberian 

 Arctic Ocean) in 75° 38' N. It is a true Arctic species. 



ARTEDIELLUS SCABER BERINGIANUS, new subspecies 

 D. VIII, 13 ; A. 10-11 ; P. 20-23 ; L. Ui. 2-^r-21. 



The structure of the head and of the body is entirely similar to that 

 of Artediellus scaher (typical). The head, the operculum, the prae- 

 operculum, and the occiput are covered with small cutaneous prickles ; 

 a narrow band of these prickles go also along the base of the first 

 dorsal fin, but no more prickles on the body are observed. Supraocular 

 and occipital cirri are long; shorter cutaneous cirri, evidently 

 originated from elongated prickles, form a row along the base of the 

 first dorsal fin. One of the two specimens (70.5 mm.) has only 4 

 such cirri in this row, the other (55 mm.) has 3 longer and 6-8 

 shorter cirri along the base of dorsal fin. Maxillary barbels are 

 short. Three cutaneous cirri are placed over the lateral line, form- 

 ing a second short row. Three other cutaneous cirri are on the 

 praeoperculum and one on the operculum. There are 6-7 subocular 

 pores, 2 small pores before, and 3 pores behind each eye. 



Coloration is light brown with small dark brown spots, not form- 

 ing regular bands. Behind the eyes is a broad white (not milky) 

 band to the margin of the praeopercle. A white spot on the base 

 of the first dorsal. On the first and the second dorsal, on pectoral 

 and caudal fins are dark cross bands. 



From the typical form of Artediellus scaher Knipovitsch this form 

 difi'ers chiefly in the smaller development of the cutaneous prickles 

 and by two rows of cutaneous cirri. But these cirri are som^ 

 times developed also by many specimens of the Arctic Ocean (as by 

 No. 21305, Zool. Mus. Leningrad) . The presence of the well-developed 

 cirri on the head brings this form in near connection with Artedi- 

 ellus ochotensis Gilbert and Burke and other Pacific species. 



Geographical distHhution. — Both specimens were found in Tkat- 

 chen Bay (64° 25' N., 172° 48' 3 W.) in the northern part of the 

 Bering Sea.
