length of the upper canines (equal 1o the incisors) indicates a 

 female, then he says, " Die Farbe ist braunrothlich. Der Bock 

 . . . . ist grosser als das Thier, und hat weisse Seiten streifen, die 

 der Liinge nach laufen. ' ' 



Taken altogether there seems little doubt that he had a female of 

 the ' ' Napu ' ' and a female of the smaller Chevrotain of Java, 

 The former from its larger size he regarded as the male, and the 

 white stripes could easily be accounted for by the whitish mottlings 

 and lighter bases to the hairs on the sides of the " Napu," which 

 produce the appearance of irregular stripes when the skin is 

 wrinkled or the hair disturbed, and contrast strongly with the uni- 

 form coloration of the sides of the smaller species. 



If this view be accepted, the name T. javanieus Osbeck will have 

 to be applied to the " Napu," as the whole of Osbeck' s description 

 applies to the " Buch " or larger of his specimens. This view we 

 propose to follow. 



If, on the other hand, it is claimed that Osbeck' s description is 

 not sufficiently clear to refer it to a definite species it will neverthe- 

 less preclude the use of the later javanicus Gmeliu, since Osbeck 

 certainly described some species of Chevrotain. The larger animal 

 (the " Napu") will then be known as T. napu Cuvier and the 

 smaller one as T. pelandoe (Ham, Smith), His description ^ and 

 reference to the plate of the " Pygmy Musk" in Shaw's Natural- 

 ists' Miscellany, I, PI. Ill, seem to sufiliciently indicate the small 

 Javan Chevrotain, but the further description given by Blvth' 

 leaves no doubt about the animal that he had in view. 



Whether the "Napu" of Java is identical with that of Sumatra 

 we are unable to say, but from the tendency it has to vary in each 

 island, as shown by G. S. Miller's recent papers, it seems hardly 

 likely, and we prefer to use Tragulus napu Cuvier for the Sumatran 

 animal, leaving T. javanicus Osbeck for the Javan form. Should 

 they prove identical the latter name of course must prevail. 



Having disposed of the imme java)iicus and the two species upon 

 which it has been bestowed, we come to the consideration of the 

 relationship of the three small Chevrotains which are united under 

 " Tragulus javanicus" in Blanford's work. The Javan species we 

 have already shown must be known as Tragulus pelandoe Ham.
