I'TEROPUS AI.ECTO. 307 



Fti)'. — Very sliort nnd eloselj' adpressed on liack. Approximate 

 lenf>:th of fur of back 7-11 mm., mantle 15 mm., belly 13 mm. 

 Width of furred space across middle of back about 32 mm. On the 

 sides of tliC back the fur is considerably shorter than in Ihc middle 

 line, in some specimens more or loss abraded, making the furred 

 area narrower than indicated above. Distribution of fur as in 

 Pt. aterrimus. 



Colour. — Series of skins (see list below, excluding 7.1.1.23S): 

 Similar to that of Pf. aterrimus, bub mantle darker, uot contrasting 

 with back. — Back and rump glossy seal-brown or blackish seal- 

 brown, often thinly sprinkled with silvery whitish hairs. — Under- 

 parts from chin to interferaoral, including flanks, blackish seal- 

 brown (a darker and less glossy tinge than that of back), generally 

 thinly, sometimes rather heavily sprinkled with greyish-whito 

 or greyish-buffy hairs. Colour as a rule blackest on throat and 

 foreneck. Mantle deep seal -brown, not differing from back 

 except in a more or less distinct maroon tinge, or chocolate clouded 

 with seal-brown, passing through a darker shade on sides of neck, 

 into the blackish of the foreneck. — Head similar to underparts. 



One specimen ($ jun. skin. Macassar, 7.1.1.238) differs in the 

 7nuch brighter colour of tlie mantle and crown : tawny hazel witli 

 blackish bases to the hairs, gradually darkening on sides of neck, 

 and merging on foreneck into general blackish seal-brown of under- 

 parts. 



Sexual differentiation. — Hairs of mantle rigid and unctuous in 

 adult males, soft, spreading, and non-unctuous in adult females. 

 In immature individuals this sexual difference is little, or not at 

 all, developed. 



Measurements. On pp. 368, 369. 



Specimens examined. Xine, in the Leyden and British Museums, 

 including supposed type of species. 



Bange. Celebes, from ^fenado to Macassar ; Salayer ; Lombok. 



Tfipe perhaps in the Leyden Museum. 



Pteropus alecto, Temminck ; 1837. — Original description based 

 on one alcoholic specimen from Menado, N. Celebes. The Leyden 

 ^fuseum possesses now no alcoholic specimen of Pt. alecto, but the 

 type may, as stated by Jentink, be the mounted skeleton. Cat. Oat. 

 p. 260, "a" (Menado, collected by Forsten), though the evidence 

 is not quite conclusive. Temminck describes the specimen as being 

 " d'une extreme vieillesse " ; the teeth of the skeleton are somewhat, 

 not extremely, worn ; according to Temminck the forearm measured 

 ')\ French inches (149 mm.), whereas the forearm of the skeleton is 

 rather more than 6 inches (164 mm.). The skeleton is, however, 

 unquestionably the species here described as Pt. alecto, and also 

 Tt inmiuck's original description agrees in every respect, except the 

 rather ton small measurement of the forearm, with this species, 

 and disagrees with any other form of Pleropus known from Celebes. 

 — Temminck's Pt. uleclon, 1853 {l.s.c), is a mixture of J't. alectc 

 and Pt. aterrimus.
