two species is very different- Lesueur, also, in his account of his R. Chantenay, speaks of 



the tail being " terminated by three rounded fins," and his figure exhibits them. Dekay, in 



his account of the above (ocellata), describes only " two small dorsals on the tail, ne: 



extremity"' 



■ 3. Raia erinacea, Mitchill. 



Form rounded; diaphanous. Pale brown, with dark-brown spots. Two dorsal fins, with 

 the vestige of a third. Two series of prickles on the tail ; a patch of about twenty erectile 

 spines on the pectorals. Prickles upon the cheeks. Snout pointed.

Body rhomboidal. Small spines on the orbits, and anterior margins of the pectoral fins ; 

 the rest of the body smooth. Three rows of spines on the tail. Snout blunted. In the 

 male, the under surface of the snout and exterior to the nostrils to the angle of the jaws,

When my Report was written, the supplement of Dr. Mitchill to his " Fishes of New 

 York," contained in the "American Monthly Magazine and Critical Review," was unknown 

 to me. Dr. Dekay is probably correct in supposing my Skalc to be the R. laevis of Mitchill, 

 and I cheerfully acknowledge it above. 



5. Raia Desniarestia, Lesueur. 



Body subrhomboidal. Brownish above, whitish beneath. Snout prominent, rounded at tip, 

 slightly emarginated each side. Many ranges of long, curved points exterior to the eyes, and 

 upon the pectoral fins ; a range of spines upon the dorsal line ; three ranges on the tail, and 

 a 6pine at each extremity of the dorsal disk ; two approximate fins on the superior extremity 

 of the tail; teeth discoidal, surmounted by a point. 



Length, 18 to 19 inches. Breadth, 124 inches. 



Florida, Lesueur.
