The Black or Pomeegra Dolphin. 
NATIVE NamMr.—Pomeegra. 
Hapitat.—Madras coast. 
DESCRIPTION.—More slender than any of the foregoing species ; 
longish snout, with 173 teeth, viz. ee It is well to note the ir- 
regularity here, not only an odd number, but the lower jaw has the 
greater number, whereas it is generally the other way. Colour almost 
black, lighter beneath. Professor Owen’s description is not so full as 
in other cases, but from the illustration it seems that the flukes of the 
caudal fin are longer, and the posterior edge of the dorsal straighter than 
in the others.

The Long-snouted Dolphin. 
HapitTat.—Indian Ocean ; coast of Ceylon.

This is also given by Dr. Kellaart as a species found on the coast of 
Ceylon. 
Sir Walter Elliot mentions another species of dolphin, of which he 
had lost the drawing, about thirty-two inches long, of a uniform black 
colour, small mouth, and*no dorsal fin, called by the Tamil fishermen 
Molagan., / 
GENUS PHOCANA—THE PORPOISES. 
No beak or rostrum; snout short and convex ; numerous teeth in 
both jaws. Kellaart testifies to the existence of a true porpoise on the 
coasts of Ceylon—which he identifies with Phocena communis—of a 
blackish colour above and whitish beneath.
