eye. Disk irregular, rhombic, its length not much less than its 

 breadth. The snout is obtuse and not projecting. The front side 

 of the pectoral fins rectilinear, the posterior slightly curved with 

 rounded sides and backward angle. Eyes moderate, their longi- 

 tudinal diameter equal to the breadth of the forehead. This last 

 is concave. The snout cartilage is narrow, expanding towards the 

 forehead. The distance between the nostrils is the same as their 

 distance from the end of the snout. The back of the disk is every- 

 where covered with minute spines, with stronger ones disposed as 

 follows : — One row along the supercilliary ridges in a curve, 

 one row in the middle line of the back, extending to the tail 

 where they are arranged in alternate irregular double rows. There 

 are also large spines on the side of the tail, especially at the base ; 

 there is also a group of smaller spines on the cartilage of the 

 snout. The teeth are in 42 longitudinal rows and are not acute. 

 The ventral fins are long, their outer margin lobed, the front part 

 with projecting points. Tail very depressed, a slight fold along 

 the side, and compressed at the extremity, no distinct caudal fin. 

 The two dorsal fins are close together, close to the tail, equal in 

 size and rounded ; the shoi't space between these two fins bears a 

 few spines. Colour grey, underneath white. 50 Ctm.
