Miller — Eleven New Malayan Mouse Deer. 41 



Weight.— Type, 2.4 kg. Adult male (No. 115,519) 1.8 kg. 



Sp< cirru ns examined. — Five, all from the type locality. 



Remarks. — This species differs from all other known members of the 

 kanchil group in its dark, rich color and broad but inconspicuous nape 

 stripe. Its characters are in every way parallel with those of the napu 

 of the same island. 



Tragulus ravulus, sp. nov. 



1000. Tragulus javanicus Miller, Proc. Biol. Soc. Washington, XIII, 

 p. 192. December 21, 1900. Part, specimens from Pulo Adang. 

 Not Gervus javanicus Osbeck. 



Type. — Adult female (skin and skull), No. 104,717, United States Na- 

 tional Museum. Collected on Pulo Adang, Butang Islands, December 

 1(5. 1899, by Dr. W. L. Abbott. Original number, 161. 



Characters. — Similar to Tragulus rants of Trong, Lower Siam, but 

 smaller, the neck paler, and the nape stripe more ill defined. 



Color. — The color so closely resembles that of Tragulus ravus* as to 

 need no detailed description. The back and sides are light ochraceous- 

 buff clouded with black, the two colors almost equally mixed, though 

 the black is a little in excess on back. Throat markings and under- 

 pays as in T. ravus. Neck a lighter shade of ochraceous than in the 

 mainland animal, and nape stripe ill contrasted with surrounding parts. 



SJcuU and teeth. — The skull is not distinguishable from that of Tragulus 

 rants, but the teeth, particularly the upper premolars, appear to be 

 more robust. The material at hand, however, is not extensive enough 

 to prove that this character is constant. 



Measurements. — External measurements of type: total length, 525; 

 head and body, 450; tail vertebrae, 75; hind foot, 113 (103); ear from 

 meatus, 32; ear from crown, 27. Measurements of an adult male from 

 the type locality: total length, 518; head and body, 455; tail vertebra, 

 63; hind foot, 112 (102). Skull of type: greatest length, 96; basal length, 

 89; zygomatic breadth, 41.8; diastema, 11. 



Weight.— Type 1.8 kg. Adult male, 1.6 kg. 



Specimens examined. — Two, both from Pulo Adang. 



Remarks. — Although closely related to Tragulus ravus the kanchil of 

 Pulo Adang appears to be sufficiently distinct to need recognition by 

 name, though relative unfamiliarity with the group led me in 1900 to 

 place it with the mainland form. 



Tragulus lancavensis, sp. nov. 



1900. Tragulus javanicus Miller, Proc. Biol. Soc. Washington, XIII, p. 

 192. December 21, 1900. Part, specimens from Pulo Lankawi. 

 Not Cercus javanicus Osbeck.
