c?. 2560, 2561, 2563. $. 2562, 2564. Kia-ting-fu, S. Sze- 

 chwan. 1200'. 



Apparently indistinguishable from the type, with which 

 Dr. Andersen has eompai'eil it. 



2. Barbastella darjelingensis Hodgs. 



c?. 2523. Omi-san. 9500'. 



A specimen of this rare species was also obtained in Sze-chwan 

 — at Yin-shin-wan, N.W. of Chong-tu — by Mr. W. IST. Fergusson. 

 I can find no difierence between these specimens and Hodgson's 

 type from Darjiling.

 Collected 23 June, 1910. Type. 



Most nearly related to P. ivardi, but da.rker. 

 ■ Size among the largest of the genus. Far of medium length. 

 General colour dark " broccoli brown," the ends of the hairs dull 

 drab. Under surface 'paler drab, the bases of the hairs dark 

 slaty. Muzzle blackish. Proportions of thumbs and hind limbs 

 as in sacrimontis. 



Skull large, with swollen brain-case and broad interorbital 

 reo'ion. Bulla? large, only less than those of the Egyptian species 

 P. chrisiiei. 



Dimensions of the type, the starred measurements taken in the 

 flesh :— 



Forearm 44 mm. 



Head and body 53* mm. ; tail 57* ; ear 43* ; third finger, 

 metacarpus 39-5, first phalanx 15-5 ; thumb (c. u., exclusive of 

 metacarpal) 9*2 ; lower leg and hind foot (c. u.) 31.

 breadth 9; intertemporal constriction 4 ; mastoid breadth 9-4-, 

 front of canine to back of m^ 5-6 ; greatest horizontal diameter 

 of bullae 4-6. 



Uab. and T'ype as above. 



Of the genus Plecotus, P. homochrous (Nepal) a,nd ptcck (Murree) 

 (doubtfulfy distinct from each other) stand aside from the rest 

 owing to their narrow brain-case ; auritus (Europe) has rounder 

 skull, small bullpe, and short thumbs; christiei* (Egypt) large 

 brain-case and very large biillfe ; vxtrdi (Ladak and Kashmir) 

 large skull, rather large bullfe, long thumbs, and very pale colour ; 

 sacrimontis (Japan) large skull, luther small bullre, and long 

 thumbs ; and finally the present species has large rounded skull, 

 large bullse, long thumbs, and dark colour. No doubt it is most 



* Althong-h the name (egi,iptiac.uis is quoted both hy Dobsou and Trouessart from 

 Is, (lenffvoy's paper of 1832, I fail to find anything but " Oreilltird d'Egypte " in 

 that pappi-j and therefore use Graj^'s name of 1838.
