Study Material. Male, 223 mm long, from the eastern slope of Georges Bank, 

 Lat. 4i°09' N, Long. 66°o2' W, in 1,255 fathoms; female, 541 mm long, from the 

 continental slope off southern New England, Lat. 39°35' N, Long. 7i°2i' W, in 

 1,043 fathoms; female, about 850 mm long, from the continental slope off Halifax, 

 Nova Scotia, in 200 fathoms ;3* all in U. S. National Museum and all collected many 

 years ago. 



Distinctive Characters. R.jenseni resembles R. hyperborea closely in general appear- 

 ance as well as in the arrangement of thorns on the head and shoulders and on the 

 midline of the disc and tail. But it is quite sharply set apart from R. hyperborea at all 

 ages in that it has 56-66 series of teeth in each jaw (38-44 in R. hyperborea); it lacks 

 large thorns on the anterior margins and midposterior parts of the pectorals and on 

 either side of the mid-dorsal ridge on the disc rearward from the shoulder region; also, 

 thorns are lacking on the rostral ridge of adults. 



Description. Proportional dimensions in per cent of total length. Male, 223 mm, 

 from Lat. 4i°o9' N, Long. 66°02' W (U. S. Nat. Mus., No. 33457)- Female, 541 mm, 

 from Lat. 39°35' N, Long. 7o°2i' W (U. S. Nat. Mus., No. 35592, type). 



33. Spelled Raia. 



34. Caught from the fishing schooner AUGUSTA H. JOHNSTON, Captain G. A. Johnston. It is catalogued as being from 

 Lat. 42° 37' N, Long. 62' 55' W, but the depth at which it was taken actually locates it as being taken a few miles 

 farther north and closer inshore.
