Size and proportions, including general body-bulk, length 

 of forearms, and size of skull, about as in true T. pachypus. 

 Ears perhaps rather narrower ; tragus rather longer and 

 narrower, its basal lobule with a longer and more acute 

 point. 



Colour above yellowish or dull gold, more or less overlaid 

 with brown. Under surface yellowisli or buffy. Limbs 

 brown, membranes black, the cushions of wrists and sole also 

 brown, not contrasted white as in T. pachypus. It is not 

 certain, however, how far this may depend on methods of 

 preservation.

I provisionally use a binomial for this bat, as it is geogra- 

 phically so isolated ; but it may hereafter be shown to grade 

 either into the Burmese form (rubida) or true pachypus of 

 Java.
