this genus nor Manis appears to be represented in Sirhassen — nor indeed does any 

 species of mammal seem to exist in that island (and proljably the other South 

 Natunas) which might not have been brought there hy flight or swimming, on 

 floating timber and vegetation, or by niiin. — A. ¥..'] 



21. Paradoxunis hermaphroditus (I'all.). 



Bunguran. 



[Native tiame " Musang." Common in cocoanut plantations on Bunguran. 



Two other carnivores, according to the natives, occur on Bunguran, and one also 

 on Sirhassen, but whether the si)ecies is the same on both islands I could not 

 ascertain. As the Malays use the name " Tengalung," they are doubtless civet-cats. — 

 A. E.]

25. Sciurus bicolor bunguranensis sulispec. nov. 



a. Type. — ad. sk. cJ. Bunguran, October 7th, 1893. 



A large series from Bunguran. 



Very similar in size and proportions to its Sirhassen representative S. h. alhlceps, 

 although rather larger and with a longer tail. General colour a peculiar pale 

 chocolate brown (perhaps nearest to " Front's brown " of Ridgway), not unlike the 

 dorsal colour of some of the Celebean iiale-footed varieties of S. hjcniar. This colour 

 is very finely grizzled with yellowish, due to the presence of narrow subterminal 

 rings of this colour on the brown dorsal hairs; there are also a certain amoimt of pure 

 white hairs intermixed. The brown extends from the forehead over the neck, back, 

 and sides, becoming on the sides of the neck, the flanks, and lower legs a deep 

 reddish or russet ; underside from neck to anus, and the inner sides of the limbs, a 

 rather paler and clearer russet, quite different from the yellowish of the ordinary 

 forms. A whitish patcli on tbe outer side of each hip. Tapper surface of muzzle, 

 a ring round eyes, whole of ears, and up[)er sm-faces of hands and feet, black. Sides 

 of muzzle, at roots of whiskers, white. Cheeks grizzled grej', darkening under the 

 chin to nearly black. Tail very long, in the upper aspect wholly brown like the back, 

 although darker, but the hairs are light-coloured at their bases, and this lighter 

 colour shows clearly on the under surface, bounded on either side by the brown tips of 

 the long hairs and the black of the short hairs with which the actual under surface 

 of the tail-substance is clothed.
