2. Ou a uew Species of Wild Pig from New Guinea. 

 By Dr. O. Finsch, C.M.Z.S. &c. 



[Received March 22, 1886.] 



The second species of true Sus from New Guinea is a very distinct 

 one, and may be separated at once from the well-known Sus papuensis 

 by the following characters: — 



Sus NIGER, sp. nov. 



Uniform blackish, even when young. 



These characters are sufficient, in all ages, to separate tiie present 

 species from Sus papuensis, which is quite different, being in the 

 adult brown, with a very distinct light-coloured mystacal stripe and 

 legs, while the young is rusty brown with light rusty-yellow stripes, 

 as in our Wild Boar.
