Membranes inserted in some individuals on postaxial side of first, 

 metatarsal, in others between first and second metatarsal or even 

 distinctly on dorsal side of second. 



Colour (skins, Kaliputjang, February and March : five males, six 

 females, all fully adult). — Essentially as in 11. amplexicaudatus, 

 but colour of underparts perhaps averaging paler (the material of 

 Ji. amjjlextcaiidatus from Sumatra and Borneo available for com- 

 parison is unsatisfactory). General colour of back some tinge of 

 dark and dull brown slightly varying individually, sometimes 

 approaching to dark Prout's brown, sometimes to dark mummy- 

 brown, sometimes again to brownish bistre ; individual hairs often 

 narrowly tipped with hair-brown or drab, particularly in shoulder 

 region and on forearms ; fur of nape of neck and rump wood-brown 

 narrowly tipped with dark brown. Head similar in colour to back 

 or slightly darker. Neck-tufts (males only) varying from deep 

 tawny-olive to deep tawny, always narrowly tip)ped with a colour 

 similar to that of surrounding fur (therefore in the arranged fur 

 only little, or not at all, contrasting with colour of neck). Under- 

 parts paler than back, some tinge of drab, broccoli-brown, or pajo 

 hair-brown, often delicately suffused with Isabella or Isabella wood- 

 brown on sides of belly. 



Immature, but nearly full-grown, individuals are similar in 

 colour to adults. Half-grown individuals are dark brown above 

 lightened with hair-brown tips to the hairs, uniform dark greyish 

 beneath. 



liemarlcs. — The three forms coin pared with each other in the 

 above descriptioTi are so intimately interrelated as to be distin- 

 guishable only by average characters ; they are evidently local 

 forms of one species, and ouglit to stand, respectively, as li. am- 

 plexicaudatiis amplexicaudaiits (Indo-3dalaya generally, excluding 

 Java), B. a. minor (Java), and It. a. brachyotis (Austro-Malaya). 



Rousettus may now be added to the list of genera which bear 

 evidence of the dual origin of the Mammalian fauna of Java. Java 

 is the only East Indian island known to be inhabited by two 

 species of the present genus : one of these, A', shortridr/ci, is closely 

 related to the Indian and Indo-Chinese A'. Icschenaidti (a type of
