that they are distinct species. Both have been called the hairy 

 rhinoceros, or Rhinoceros sumatrensis. The one comes from 

 Chittagong, and the other from Malacca ; and Mr. Blyth sup- 

 poses that the one inhabits the east coast of the Bay of Ben- 

 gal and the series of islands extending to Sumatra, and the 

 other the Malay peninsula and Tenasserim, separated in Bur- 

 mah by the Irrawaddy river. 



The one from Chittagong is covered with soft hair, and the 

 ears are surrounded by a fringe of long hairs ; I have no doubt 

 this is the double-horned rhinoceros of Sumatra, described by 

 W. Bell in the ' Philosophical Transactions,' January 10, 1793. 

 Mr. Bell describes the " general colour as brownish-ash. 

 Underside of belly between the legs and folds of skin dirty 

 flesh-coloured. Ears small and pointed, lined on the edge with 

 short black hair. Upper lip pointed and hanging over the 

 under. Whole skin rough, and covered very thinly with 

 short black hair." 



The figure represents the ears fringed with longer hair, and 

 the tail covered with longer hair and reaching two thirds of 

 the distance to the hocks. 



The following names have been applied to this species : —

I cannot conceive how the idea originated of giving another 

 name to this species. 



The length of the hairs on the margin of the ears appears to 

 vary in the different specimens ; and those in the specimen in 

 the Zoological Gardens appear to be much longer than usual. 

 Thus Dr. Anderson states that in the adult males and females 

 from Burmah the margin of the ears is fringed with strong,
