The upper side is slaty gray, the under side white but with a dark spot on eaeh side 

 of the anus and a dark band, dissolving posteriorly into spots, along the middle of the tail. 



Of the two specimens from the "Tjalfe" Expedition the first-mentioned was a male 

 1080 mm long with 48 dorsal spines, the second a female 810 mm long with 45 dorsal

spines. Regarding the colour of the last specimen I have noted the following: The 



upper side uniformly clay-gray; the under side milk-white, with a gray longitudinal 



band under the tail, from the end almost to the anus and with a white edge on each 



side ; a dark, reniform spot on each 



side of the anus. Of these specimens 



only the jaws were preser ved; in 



the male (fig. 8) there are 49 rows 



of teeth in the upper jaw, 50 in the 



lower, in the female (fig. 9) 47 in the 



upper jaw and the same number 



in the lower. The teeth of the 



female have shorter points and 



broader bases than the teeth of 



the male.

 lintea certainly occurs in the central part of the Davis Strait, which is to some extent 

 a surprising extension of its region of distribution. Hitherto Raja lintea has only been 

 known from the eastern side of the Atlantic. It has long been known, that the species
