CYNOPTERUS BRACHYOTIS. 203 



its fellows ; the more 'as Dobson has bestowed the specific 

 title of hrachyotis upon a new species of the with Cynop- 

 terus so closely allied family Cynonycteris (see P. Z. S. 1877 

 and Catalogue, 1878) and so one perhaps might confound 

 them and believe that Müller's hrachyotis would be the 

 same as Dobson's hrachyotis , meanwhile they represent two 

 well defined and really very different species , belonging 

 to two distinct families. 



Muller observed that hrachyotis is about one third smaller 

 than tithecheilum f = marginatus) , for the rest colored like 

 that species , the wings however being darker , of a sooty 

 color , meanwhile the ears present too a sooty color : Tem- 

 minck (Mon. mamm, II) compared the type-specimens with 

 Pachysoma hrevicaiidatum ( ^ C. marginatus) and remarked 

 that Müller's hrachyotis »diffère néanmoins par ses petites 

 oreilles courtes , arrondies , depourvues de toute bordure 

 marginale et de plis verticaux internes ; elles sont aussi moins 

 larges et toujours d'une couleur noire." Although Müller's 

 specimens are at present nearly white , with exception of 

 the reddish colored collar, so that the dark tinge of ears 

 and wings has disappeared (they have been preserved in 

 a stuffed state and have been bleached by the influence of 

 light) , the white margin of the ears, however, is very clear 

 to see, so that I cannot understand how Temminck over- 

 looked this characteristic and could write that the ears 

 are » depourvues de toute bordure marginale." 



But taking leave of badly preserved and bleached stuffed 

 specimens I now proceed to give a better exposition of 

 the two Cynopterus-s^Qoie^ with white-bordered ears, C. 

 marginatus and C. hrachyotis , based upon fresh material , 

 preserved in alcohol, recently received from Java and Su- 

 matra. 



C. hrachyotis at a glance is distinguished from C. mar- 

 ginatus by its white fingers , strikingly contrasting with the 

 dark wing-membranes, smaller ears, more elongate muzzle 

 and smaller head. 



The tinge of the hairs on the back of C. marginatus is
