 Rough Ray. Penn, Brit. ZooL 



Greatly allied to the Thornback, but covered 

 with more numerous spines, every part of the skin 

 on the upper surface being muricated wdth sharp 

 curved aculei of different sizes : of these one row 

 of the largest runs down the middle of the back, 

 and three, or, sometimes, five, along the tail : others 

 are dispersed about the region of the eyes and the 

 flaps of the pectoral fms : the general colour is a 

 yellowish or whitish grey, sometimes variegated witk 

 dusky or brownish clouds and streaks : the under 

 side is white, and beset with very numerous s^^at- 

 tered spines, but less strong than those on the 

 upper side : the general size of this species is the 

 same with that of the Thornback. A specimen 

 observed by Mr. Pennant measured nearly three 

 feet from the nose to the tip of the tail. It is a 

 native of the Mediterranean and other seas. The 

 teeth in this fish are sharp-pointed ; in the Thorn- 

 back obtuse.
