miller] seventy new MALAYAN MAMMALS 5 1 



Specimens examined. — One, the type. 



Remarks. — Although represented by one specimen only, this 

 species is undoubtedly distinct from the Galeopithecus volans of 

 the Malay Peninsula and from the form inhabiting Sirhassen Island. 

 It appears to be more closely allied to the former, a fact in har- 

 mony with the relationship of other Bunguran mammals, notably the 

 giant squirrels. 



GALEOPITHECUS SATURATUS sp. nov. 



(Plate VII, figures 3 and 4; Plate VIII, figures 3 and 4; Plate IX, 



FIGURES 3 and 4) 



Type. — Adult female (skin and skull), No. 121,750, United States 

 National Museum. Collected on Tana Bala, Batu Islands, Sumatra, 

 February 12, 1903, by Dr. W. L. Abbott. Original number, 2278. 



Characters. — Slightly larger than Galeopithecus volans, and sexual 

 difference in size less noticeable than in the other known species. 

 First upper incisor usually with four cusps. Color very dark, the 

 light phase not unlike the dark phase of Galeopithecus volans. 



Color. — Light phase (type specimen) : dorsal surface mostly 

 ochraceous-buff and seal-brown, the former predominating on body, 

 hind legs, and interfemoral membrane, the latter nearly clear on 

 forearms. Neck washed with gray, shoulders and back with cream- 

 buff. Face suffused with dark brown. The colors are everywhere 

 indescribably blended. On each hip there is a conspicuous buffy 

 white spot, and two similar but smaller spots occur behind each 

 shoulder. The feet and edges of the principal membranes are 

 speckled with grayish white dots. Dark area of forearm intensified 

 by about six conspicuous buffy white spots 3-8 mm. in length and 

 about 2 mm. wide. Under surface of body drab washed with wood- 

 brown. Under surface of legs and membranes tawny clay-color con- 

 siderably lighter than that of Ridgway. Dark phase (adult male, 

 No. 121,749) ; general color above seal-brown, faintly grizzled with 

 russet on interfemoral membrane, lumbar region, and sides of back. 

 On front legs and feet and over most of the membranes there is a 

 noticeable sprinkling of whitish hairs, these most conspicuous on 

 forearm. Neck dull, grizzled wood-brown. Head blackish, sprinkled 

 with silvery white hairs. Hip spots indicated by a few tufts of 

 creamy white. White spots on shoulders and forearms obsolete. 

 Underparts as in the light phase, but wood-brown and drab rather 

 darker, and interfemoral membrane heavily washed with an indefi- 

 nite dark brown. Red phase (adult male, No. 121,853) : entire 

 upperparts bright cinnamon-rufous, the hairs fading to orange-buff 

 beneath the surface of the fur. Neck slightly grizzled with wood-
