ber of pores in the lateral line, we must still consider tliem as two 

 different species. 



Geographical dist'ribution. — This species is knoAvn from Green- 

 land, Davis Strait, and the east coast of North America from Labra- 

 dor southward to Cape Cod.

This form confused by other authors with the American form, the 

 true Artediellus uncinatus Reinhardt was separated by Knipovitsch 

 as a different species. 



The number of pores in the lateral line is 27-30. On the dorsal 

 and pectoral fins the white crossbands on the dark brown ground are 

 continuous and not formed by rows of round white spots. The 

 length of the pectoral fins is given by Knipovitsch as 22-24.9 of 

 the length of the body, but in this respect there is a very small 

 difference between this species and the Ai^tediellus uncinatus Rein- 

 hardt, as this last species has the fins of 22.7-26.7% of the length of 

 the body. The length of the body (measured with caudal fin) can, 

 according to specimens in the Leningrad collection, reach 133.5 mm. 



Geographical distrihution. — This species is distributed in the east- 

 ern part of the Atlantic Ocean. It is known from Spitsbergen, 

 west coast of Norway, and the Murman coast (Barents Sea).
