Snout long and pointed ; the width of the iuterorbital space is contained about four 

 times and one half in the length of the snout. Body above smooth, rough only on the 

 snout and the upper margin of the eye, in some old specimens also along the front margin 

 of the disk ; the body below thickly covered with minute a.sperities. No larger spines 

 on the disk. The tail in the males with a median series (containing about forty spines), 

 but none on the sides ; the old females with three series, the median series containing a 

 varying number of spines, some of which are sometimes irregularly crowded together. 

 Between the dorsals there are, as a rule, a few spines. The teeth form from forty-one 

 to forty-four series in the upper, and from forty-one to forty-three in the lower jaw. 

 Coloration dark greyish-brown above ; the mucous pores marked with black vermicular 

 spots. Lower surface blackish, without spots. 



This species is locally not uncommon on the Norwegian coast, for instance in 

 Throndhjem Fjord, at a depth of 150 to 200 fathoms. It is one of the larger skates, the 

 specimens in the British Museum measuring from 38 to 46 inches in width.
