264 Gr. E. Dobson — On Malayan Bats. [No. 3, 



Front edge of the horse-shoe portion of the nose-leaf raised, 

 bent up in the middle, and separated from the lip by an underly- 

 ing fold of membrane ; on each side of the horse-shoe a double fold 

 of membrane ; upper transverse nose-leaf large, erect : upper por- 

 tion, or crest, convex in front, overhanging the base which is concave, 

 .and divided into four shallow cells by three longitudinal folds ; the 

 form of the crest is that of an isosceles triangle with an obtuse 

 vertical angle ; the apex of this triangle is divided into three points 

 by two narrow perpendicular incisions extending half way to the 

 base, the extremities of which are attached to the membrane 

 forming the horse-shoe by a vertical band on either side. 



Behind the upper erect nose — leaf on either side, above the eyes, 

 a wart-like prominence is placed, having on its summit the open- 

 ings of two minute pores from around which long straight hairs 

 arise. 



Wings broad, wing membrane attached to lower part of 

 ankles ; thumb moderate ; terminal phalanges of third and fourth 

 fingers bifid at their extremities, each division nearly one-sixth 

 of an inch in length, or longer than any observed by the writer 

 in the largest Bhinolophine bats. Tail of six joints, last two 

 vertebrae free. 



The body is covered with long, silky fur ; above bi-coloured, 

 pure white at the base, and for two-thirds its length, the remaining 

 portion purplish-brown ; beneath dirty white throughout. Cutane- 

 ous system pure white. 



On the upper surface the wings and interfemoral membranes 

 are completely devoid of hair with the exception of a very narrow 

 portion along the sides of the body and at the root of the tail on 

 which the fur of the back extends ; beneath, the wing membrane, 

 as far as a line drawn from the elbow to the knee joint, is covered 

 with short hairs, ranged along the parallel lines with which it is 

 marked in this region ; behind, the fur of the abdomen passes on 

 to the interfemoral membrane, occupying about one-third of its 

 surface. 



The bones of the extremities are extremely slender and light, and 

 the membranes so translucent, that letters of small type can be 

 distinguished through them even when dry.
