MUNTIACUS PLEIHARICUS Kohlbrugge. 



1896. Cervulus pleiharicus Kohlbrugge, Natuurk Tijdschr. Nederlandsch- 

 Indie, vol. 55, p. 192, and plate facing p. 260. Type-locality, Pleihari, 

 southeastern Borneo. 



In 1906 x I described as new a muntjac from the island of Banka, 

 comparing it with specimens of Muntiacus moschatus from Sumatra, 

 and with three Bornean muntjacs. At that time I assumed that 

 there was only one species of muntjac on Borneo and used Kohl- 

 brugge's name pleiharicus for it, thinking that the antlers he figured 

 were slight variations from the normal type and having seen a pair 

 of similar looking antlers from Tenasserim. Two of those Bornean 

 specimens are females and the third is a pair of antlers from the 

 Sakaiam River. With the much more abundant material that has 

 been collected by Doctor Abbott in Borneo, I quite agree with 

 Kohlbrugge that two distinct forms of muntjac occur on Borneo, 

 and now consider that the two female specimens were correctly 

 identified as M. pleiharicus in 1906, but that the single pair of antlers 

 do not represent M. pleiharicus but belong to a species to be described 

 below and of which the Banka animal is merely a slightly smaller 

 geographic race. 



Doctor Abbott secured six specimens of Muntiacus pleiharicus, three 

 from southwestern and three from southeastern Borneo; one young 

 female, two immature males, and three adult males. The antlers of 

 the adult males represent a much more extreme type than do those 

 figured by Kohlbrugge. It is not improbable, however, that they 

 are newly-formed antlers, although the bone forming them looks 

 fully mature and as if they had not been recently covered with velvet. 

 The following is a description of M. pleiharicus based on Doctor 

 Abbott's specimens: 



General color of the animal a light, dull ochraceous, somewhat like 

 ochraceous-buff, darker and brighter along the middle line of the 

 back and neck, where there is a considerable admixture of a brown 

 somewhat like Prout's forming an indistinct dorsal line; ears dull 

 brownish on the outside, whitish on the inside; bases of ears similar 

 to adjacent portions of head; chin, under side of neck, inner side of 

 fore legs, and inguinal region whitish to cream-buff; hind legs and 

 outer side of fore legs similar to the general pale ochraceous head and 

 body color, except for a slight admixture jf brownish along the 

 lower legs, most marked on the fore legs; tail whitish, with a narrow 

 dorsal stripe of dark brownish slightly mixed with ochraceous. 

 Compared with the other species of Bornean muntjac, Cat. No. 

 151863, adult male from Pamukang Bay, M. pleiharicus is very dif- 

 ferent. The general color of the other is a bright reddish-brown,
