two species is very different. Lesueur, also, in his account of his R. Chantenay, speaks of 
the fail 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, near its 
extremity.”

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 
tome. Dr. Dekay is probably correct in supposing my Skate to be the R. levis of Mitchill, 
and I cheerfully acknowledge it above.

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

a spine at each extremity of the dorsal disk ; two approximate fins on the superior extremity 
of the tail; teeth discoidal, surmounted by a point.
