11. Galeopterus lechei sp. n. 



No. 4889. $ Toemhang Mnroewe, Central Borneo. Oct. 1915. Hindfoot: 60 mm. (measured in skin). 

 Tail: 95 mm. — No. 24. $ Toembang Maroewe, Cential Borneo, Ort. 1915. Hindfoot: 58 nnn. (measured 

 in skin). Tail: 126 mm. — No. 3. $ imm. Toembang Maroewe, Central Borneo, Sept. 1915. Hindfoot: 

 49 mm. (measured in skin). Tail: 50 mm. 



Type: Adult female (skin and skull). Collected at Toembang Maroewe, Central 

 Borneo. Oct. 1915 by Mr. C. Lumtioltz. Type in red phase. (Original number 24.) 



Cknraciers: Similar to G. borneanus Lyon but distinguished by its short tail 

 and short hindfoot. The colour in the grey phase is similar to that of borneanus 

 but everywhere more intermixed with tawny ochraceons hairs, making the general 

 colouration browner and less grey. 



Description of type: General colour above orange rufous nearest to »Sanford's 

 brown» (Ridgway pl. 2) the hairs being orange pink at base. Sides of neck slightly 

 paler than the remainder of the upper parts. Along the sides of the body a few 

 pure white blotches most numerous on the posterior parts. On each side of the 

 neck a white spöt. Below the eye a half moon shaped orange pink area. FI}*ing 

 membrane oramre rufous though darker than the upper surface of the body. Outer 

 margins of flying membranes paler and spotted with yellowish brown. Hands and 

 feet with similar spöts. Along the forearm these spöts become larger and more 

 longitudinal and the innermost ones are whitish. Lower surface of body orange 

 rufous but lighter and more pinkish than the upper parts of the body. Flying mem- 

 branes when seen from below darker. 



Skull and teeth: The general form and shape of the skull resembles that of the 

 Sumatran animal {G. temminckii Waterh.) though it is much smaller and the 

 toothrow more rounded. The teeth of the new form are much smaller than in either 

 borneanus or temminckii. The nasals are not pinched up into a ridge or only feebly 

 so thus in contrast to the nasals of peninsulre, temminckii, variegalus and borneanus. 

 The basioccipitale is of about the same size as that of the Javan form (viz. varie- 

 gatus) and broader than in borneanus. 



Description of light phase: General colour above various shades of greyish yellow
