Twenty-seven specimens of this well-marked species of mouse-deer 

 have now been sent to the National Museum. At the time it was de- 

 scribed it was known by but a single specimen taken by Mr. C. Boden 

 Kloss on Batam Island. Since then Mr. Kloss has collected 9 addi- 

 tional specimens on Batam. and 3 from Gong Hill, Pulo Galang. 

 Doctor Abbott has recently collected 6 on Pulo Setoko and 8 on Pulo 

 Bulan. The amount of individual variation in this large series is not 

 great so far as color and markings are concerned, consisting chiefly in 

 the intensity of the yellow color on the upper parts of the body behind 

 the shoulders. In some individuals the black tips of the hairs on the 

 back are quite conspicuous, thus obscuring the yellow color. The 

 neck, however, in all the specimens is always strongly yellowish, 

 without admixture of darker colors, and in none of the specimens does 

 il make any approach to the neck coloration found in Tragulus flavi- 

 collis Miller from Pulo Sugi. The type-specimen of T. perfavus is 

 about the average of the series so far as color is concerned. 



In external and cranial measurements there is more individual 

 variation in the series than there is in the color and markings. See 

 table.
