1. LIST OF MICROCHIROPTERA, OTHER THAN' 

 LEAF-XOSE BATS. IN THE COLLECTION OF 

 THE FEDERATED MALAY STATES MUSEUMS. 



By Oldfield Thomas, F.R.S. 



,1 owe to the kindness of Mr. H. C. Robinson the oppor- 

 tunity of examining certain of the bats preserved in the 

 collection of the F.M.S. Museums, and at his suggestion I have 

 written the following list. It contains the Microchiroptera 

 other than the Leaf-nose bats, with which latter Dr. Andersen 

 is dealing. By the generosity of the authorities of the F.M.S. 

 Museums the British Museum has been permitted to retain a 

 number of the specimens here enumerated, including the tvpes 

 of the three new forms described. 



Eptesicus dimissus, sp. nov. 



Eptesicus pachyntis, Robinson & Kloss, Journ. Fed. Malay 

 States Mus. V. p. 116 119141. 



Type. 9 in al. Kao Nawng, Bandon, Malay Peninsula 

 3,500'. June 1913. F.M.S. Mus. No. 529/13. Collected by 

 H. C. Robinson and E. Seimund. 



A medium — sized species related to E. pachyotis. Size 

 rather greater than in E. pachyotis. Body proportionally rather 

 larger compared with the wings. Fur short (hairs of back 

 about 3 mm. in length 1, rather >parse, mostly confined to the 

 body except on the interfemoral, on a triangle at the base of 

 the tail. Colour chestnut brown above, lighter below, the 

 haiis of the mesial area of the understirface broadly tipped with 

 dull whitish or huffy. Ears short, rattier narrow, inner base 

 with a rounded basal lobe; inner edge slightly convex, tip 

 rounded off, outer edge straight above, convex lower down, 

 with a low antitragal lobe. Tragus short, its inner margin, 

 which is scarcely longer than its breadth, slightly concave, tip 

 rounded, outer margin convex with a fleshy basal lobe. Wings 

 to the middle of the metatarsals. A distinct post-calcarial 

 lobule. 



Skull broad and stoutly built, with a well marked occipital 

 "helmet." Upper incisors with less disparity 111 size than in 

 the allied species, the tip of the outer attaining three fourths 

 the height of the inner, the latter rather small but still of the 

 characteristic Eptesicus shape, parallel sided, bicuspid ter- 

 minally; the outer tricuspid, obliquely concave. Last lower 

 molar with its posterior portion nearly equal to the anterior 

 part in area, and similar to it, as in nvst of the smaller species 

 of the genus 



Dimensions of the type, measured on the spirit specimen. 



Forearm, 42 mm.
