Except in the case of Mus bceodon, the above measure- 

 ments are not taken from the skulls of the actual types, as 

 skins have been whenever possible selected as types, and the 

 native skinners have unfortunately always cut off the backs 

 of the skulls during the process. These measured skulls have 

 been extracted from spirit-specimens which have been care- 

 fully compared and found to agree with the typical skins. 



LIX„ — Descriptions of Two new' Bats of the Genus Kerivoula. 

 By Oldfield Thomas. 



Mr. John Whitehead's expedition to the Northern Philip- 

 pines has resulted in the discovery of one, and Mr. Charles 

 Hose's explorations in Eastern Sarawak in that of the other, 

 of the two following new species, which, belonging to the 

 group comprising K. Hardwickei, K. pellucida, and K. papil- 

 losa, are clearly distinct from any of them. Of these three 

 old species the last-named is at once distinguishable from 

 either of the new ones by its much greater size, and K. pel- 

 lucida by its longer ears, so that K. Hardwickei is the only 

 one with which it is necessary to compare them. 



Kerivoula Whiteheadi, sp. n. 



Size and proportions about as in K. Hardwickei, but the 

 ears are slightly longer and the lower legs shorter. Upper 

 surface of wing-membranes to a line drawn from the elbow 

 to the foot, whole of interfemoral membrane except the ter- 

 minal half-inch, and surface of lower limbs to feet thinly but 

 distinctly clothed with long orange-coloured hairs, these parts 

 in K. Hardwickei being practically naked. Forearm, carpus, 

 and index also thinly clothed. Hinder edge of interfemoral 

 with a few short hairs along it, scarcely forming a fringe. 



Colour above rufous-orange, the slaty bases to the hairs
