Hah. Carl Island and Cape Torell, in 12-15 fathoms. 



The colour of the animal is light brown, with very short cinereous 

 hairs, which render it scabrous to the touch ; the legs are banded 

 with very fine longitudinal lines of a deeper brown. The joints of 

 the tarsi are subequal ; the second joint of the palpi is rather longer 

 than the third. This species is evidently very nearly allied to N. 

 grossipes, Fabr., as described by Kroyer (Nat. Tidsskr. n. R. i. p. 108, 

 1844) and figured (Voy. en Scand. pi. xxxvi, fig. 1) ; but in that 

 species the third joint of the palpi is much longer than the second, 

 and the animal is described as glabrous. 



Leach's specimens of N. gracile in the collection of the British 

 Museum are much smaller and slenderer than the specimens from 

 Spitsbergen; but the proportional length of the joints is the same, 

 and it is evident that the animal becomes more robust as it increases 

 in age.
