42 Miller Eleven New Malayan Mouse Deer. 



Type. Adult female (skin and skull), No. 104,412 United States Na 

 tional Museum. Collected on Pulo Lankawi, off west coast of Malay 

 Peninsula (about 75 miles north of Penang), December 7, 1899, by Dr. 

 W. L. Abbott. Original number, 132. 



Characters. Similar to Tragulus ravus but general color slightly more 

 yellow and underparts extensively washed with orange-buff. 



Color. The color is very similar to that of Tragulus ravus, but the 

 ochraceous-buff of the upperparts is noticeably brighter and more 

 yellow, particularly that of back and sides. Chest and anterior half of 

 belly strongly washed with dull orange-buff along median line, this suf 

 fusion tending to spread at sides so as to separate white of inguinal re 

 gion from that of front part of chest. While this character is not wholly 

 constant, it is sufficiently prevalent to impart a very different aspect to 

 series of specimens of the two species. 



Skull and teeth. The skull and teeth do not differ appreciably from 

 those of Tragulus ravus, though they probably average somewhat 

 larger. 



Measurements. External measurements of type: total length, 520; 

 head and body, 455; tail vertebrae, 65; hind foot, 117 (105); ear from 

 meatus, 34; ear from crown, 29. Average of six adult females from the 

 type locality: total length, 521 (505-545); head and body, 456 (435-480); 

 tail vertebra, 65 (65-65); hind foot, 118 (115-119); hind foot without 

 hoofs, 105.5 (102-107). Skull of type: greatest length, 99; basal length, 

 94; zygomatic breadth, 42; diastema, 12. 



Specimens examined. Thirteen, all from Pulo Lankawi. 



Remarks. The more extensive material now at hand brings to light 

 differences between this animal and the mainland from which passed 

 unnoticed when I examined the island series in 1900. The yellowish 

 suffusion on the underparts suggests that of the bright colored species 

 from Sinkep, Linga, and the Rhio Archipelago, but is much less intense. 



Tragulus lampensis sp. nov. 



Type. Adult female (skin and skull) No. 104,429, United States Na 

 tional Museum. Collected on Pulo Lampee or Sullivans Island, Mergui 

 Archipelago, February 4, 1900, by Dr. W. L. Abbott. Original number, 

 299. 



Characters. Similar to Tragulus lankavensis, but yellower throughout, 

 particularly on underparts. 



Color. The color is in general like that of Tragulus ravus and T. lan- 

 cavensis, but is more strongly yellow than in either. The wash on the 

 underparts is of the same extent as in T. lancavensis, but is a bright 

 orange-buff. 



Skull and teeth. I cannot see that the skull and teeth differ from those 

 of the related species.
