Animal 5 — 8 feet long, with a long compressed snout, a vaulted 

 compressed forehead, longitudinal blow-hole, scarcely perceptible eye, 

 distinct neck, broad and abruptly truncated pectoral fins and a small 

 (or rudimentary) dorsal fin; snout in males shorter {Anderson, A. and 

 Z.Res.); ear-hole semi-lunar; teeth 27 on each side in the lower 

 jaw, 26 in the upper — total 106, sometimes less. A specimen from 

 the Indus, 4i feet long, had pectoral fins or paddles, 7^ inches by 5, and 

 a rostrum of 10^ inches. Colour reddish salmon all over the body, 

 except the tail, which was brownish grey. The dry skin becomes 

 a pearly grey throughout. 



Dr. Gray, in his Cat. of Seals and Whales, Br. Mus., says : — That the 

 skull of the Indus porpoise presented by Sir A. Burnes is conspicuously 

 difterent from that of P. Gangeticus, that the maxillary crests are 

 wanting, and that the skull is more robust. He gives the length 

 of skull as 20^ inches, and the greatest width at zygomatic arches 

 9^", the symphysis of lower jaw 11 inches, length of the animal 7 feet. 

 Dr. J. Anderson, F. R. S., Superintendent of the Indian Museum, after 

 ■working up the question of separating the Indus and Gangetic species, 

 concludes that the Indus porpoise does not differ in any very essential 

 character to justify a separation. In his Anatomical and Zoological 

 Researches will be found a very exhaustive description of the ana- 

 tomy of this species. He has also, from personally watching its habits 

 in a captive state, given a most interesting account of its mode of 

 respiration, &c. 



Hab. — The larger rivers connected with the Ganges, the Brahma- 

 pootra and Indus Rivers.
