West Greenland. In the Davis Strait, west of the "Store Hellefiskebanke" 3 

 specimens in all have been taken of this large ray, namely at: 



66°35' N., 56°38' W. 318 fm. 3.9° C. 11. 7. 1895. "Ingolf" St. 32. Trawl. 



66^45' N., 56°39' W. 241—202 fm. 3.4—3.3° C. 6. 7. 1908. "Tjalfe" St. 103. Line. 



66°53' N., 56°17' W. 225—210 fm. 3.4° C. 21. 8. 1908. "Tjalfe" St. 206. Line. 



The first of these specimens was described by Lutken, who thought it was a new 

 species, Raja ingolfiana. It is a male 662 mm long, still young, the appendices genitales 

 being only 35 mm long and quite undeveloped. It has the typical form of Raja lintea 

 (cf. figure in Lutken). This ray belongs to the long-snouted species ; in the present Green- 

 landic specimen the length of the snout, measured from the point to a cross-line drawn 

 through the centre of the eyes amounts to 123 mm or more than half the breadth of 

 the disc across the eyes (224 mm). The length of the tail, from the posterior margin 

 of the anus, amounts to 327 mm or almost half the length of the whole body. The prin- 

 cipal measurements otherwise are the following: greatest breadth of the disc 427 mm, 

 least distance between the eyes 33 mm, longitudinal diameter of the eye 15 mm, longest 

 diameter of the spiracle 14 mm, distance of the nostrils from each other anteriorly 57 mm, 

 distance of the mouth from the tip of the snout 125 mm, breadth of the mouth 

 60 mm. 



The largest spines, 47 in number, are situated along the mid line of the back and 

 tail; on each side of the tail there is a row of smaller spines, and the upper side of the 

 tail is rough from numerous, very fine spines, which form a longitudinal band on each 

 side, between the rows of large spines. In front of the eye there are 2 spines, at its inner 

 border 1 spine, behind the eye 4 spines and 3 over the shoulder forming a triangle. Other- 

 wise the upper surface of the body is sparsely provided with small spines, excluding 

 the anterior lateral margins of the disc, where there are coarse small spines with stellate 

 base, as also the cartilaginous snout, over the anterior part of which is an elongated 

 area with ca. 15 similar, but somewhat larger spines. The belly is completely naked.
