1871.] G. E. Dobson — On a new Genus of lihinolop/udce, Sfc. 459 



In a future paper on the osteology of the type species I hope to 

 be able to show that, apart from the characters presented by the 

 nasal appendages, there are points of difference in the construction 

 of the bony skeleton which still further separate this genus from 

 all other genera of Rhinolophidce. 



The specimens from which the description of Tricenops perstcus 

 is derived, were obtained at an elevation of about 4750 feet near 

 Shiraz in Persia ; at the same place specimens of four other species 

 were also taken, of which one is new, belonging to the sub-genus 

 Vesperus* Keys, et Bias. 



Yespeeus Shiraziensis, Dobson. 



Muzzle broad and thick ; head flat ; nostrils opening sublateral- 

 ly with a shallow emargination between ; ears triangular with 

 rounded tips, inner margin convex, outer margin faintly hollowed 

 out beneath the tip, becoming slightly convex below, again hol- 

 lowed out opposite the base of the tragus, and terminating towards 

 the angle of the mouth in a small lobe ; tragus long, rounded at 

 the tip, with a very slight inward curvature, inner margin almost 

 straight, outer margin slightly convex with a small triangular lobe 

 at the base. 



Wings broad ; wing membrane attached to base of outer toe ; 

 terminal phalanx of thumb nearly twice the length of basal ; feet 

 moderately long, slender ; toes more than half the length of the 

 whole foot. 



The fur of the back is moderately long, and scarcely extends 

 on to the wing membrane except in the immediate neighbourhood 

 of the sides of the body, and on the interfemoral membrane at the 

 root of the tail ; beneath, the wing membrane is covered to a 

 greater extent, and fine thinly spread hairs pass out along the 

 posterior margin of the humerus and forearm to the carpus ; the 

 fur of the abdomen scarcely extends to the interfemoral membrane, 

 but very fine, almost invisible, hairs rise from the transverse dotted 

 lines with which it is marked. The fur of the head passes for- 

 wards upon the face slightly in front of the eyes, the remaining
