pointed, and the outer margin very faintly hollowed out towards the 

 tip. 



The wings are rather long and narrow, the fourth finger not ex- 

 ceeding in length the two basal phalanges of the longest finger. 

 Thumb short, more than half enveloped in membrane. 



Fur of the upper parts tricoloured, dusky-grey at the base, suc- 

 ceeded by yellowish-brown, and this again by darkish umber-brown, 

 with the extreme tips a little paler. Beneath, the fur is faintly 

 bicoloured, lightish brown at the base, with the tips of the hairs 

 rather paler. 



The specimen in my own collection, from Sarawak, differs in having 

 the colours much more vivid. Fur of the upper parts bright cinna- 

 mon-brown for two-thirds of its length, succeeded by bright rufous 

 of a somewhat darker hue, with the extreme tips of the hairs a little 

 paler, giving, when viewed in some lights, a slightly hoary appear- 

 ance. Beneath, the fur is lightish rufous, a little darker at the root 

 than at the tip. Membranes rather dark and shining. 

 The following are the dimensions of these specimens : —

Obs. — The species to which this is most nearly affined is the 

 Phyllorrhina speoris ; but it may be readily distinguished by the fol- 

 lowing points of difference : — P. speoris is constantly somewhat 

 larger than the present species, and has the head, but more espe- 

 cially the canine teeth, considerably larger. The tibia?, too, are not 

 only longer in actual measure, but also longer in relation to the size 

 of the animal, in P. speoris, than in the present species. Again, in 

 P. speoris the free portion of the thumb is longer than the enclosed 

 part, whilst in the present species the enclosed portion is the longer. 

 To these differences may be added, that the membranes are much 

 less translucent, but more shining, in the Labuan species than in 

 P. speoris. 



4. SCOTOPHILUS NITIDUS, n. S. 



In M. Temminck's monograph of the genus Vespertilio, several 

 small Asiatic species are described which are affined to the common 

 Pipistrelle Bat of Europe, and appertain to the genus Scotophilus.
