The. fins. The two distinct ventral fins are rather distant from the lateral, and of the same triangular form; 
The first dorsal is nearly opposite to the ventral, the second two inches lower down: both are falcate, at the 
anterior as well as posterior edge, but the posterior point is obtuse. The tail becomes rounder below the first 
dorsal, and tapers rapidly to the caudal fin, which is long, broad, and obliquely falcate. 
The colour of the fish a light brown. The skin, when stroked upwards, has a harsh rough feel, but a soft, 
velvet-like feel, when stroked downwards.

REMARKS. 
This fish, in some respects, resembles the Raja rhinobatos, bift is widely different in others. The spots on 
the lateral fins, and on the back, render it remarkable.

Raja corfiore oblongo ; rostro productiore , acuto , aculeis rejlexis dufilicc serie exasperato, tuber- - 
cidis spinosis , or dine nnica in medio dor si dipterygii ; cauda pinnata. 
The Raja with an oblong body ; an elongated, pointed rostrum, armed with a double row 
of reflex prickles; a single row of spinous tubercles along the middle of the back, and 
between the two dorsal fins; the tail pinnated. 
Called by the Natives Suttiwarah. 
The body oblong, depressed. 
The head broad, and flat, but raised sufficiently from the surface to be distinguished from the body, and lines 
corresponding to the spiracula, are visible behind. The rostrum long, trigonal, pointed, with two diverging 
rows of prickles in the middle, extending from near the edge of the foramina; similar prickles are thick set 
between the eyes, and on the sides. The eyes and foramina, the mouth, teeth, and nostrils, as described in the 
last subject. The trunk. A row of spinous tubercles, on the middle of the back, are continued as far as the 
second dorsal fin: small prickles and smooth tubercles being interspersed. 
The. fins. The lateral fin, rising higher than the eyes, at first bends gently in, but soon bellying outwards, 
forms a lobe nearly semicircular on each side. The ventral are immediately behind, much smaller, but of the 
same shape, and form a second circular expansion. The two dorsal fins are on the middle of the tail, with two 
spinous tubercles between them; the caudal is oblique, and entire. 
The colour, a light brown, the underside as usual, white.
