similar small differences. Neitlicr tl\e external characters nor the skull 

 agree with L. rufescens. 



The following is a summarized list of the sj^ecics above discussed : 



1. VuJpes montanus. 



2. LiUra, either L. vulgaris, var. or an allied species. 



3. Mus, probably new, allied to M. Bactrianus. 



4. Lepus Biddulphi, sp. nov. 



5. Lagomys ai(,ritus ? var. 



XVI. — On a supposed new Sheep from the Central Hills of Kelat. — JBy

(Received 30th Octoher; Read 7th November, 1877.) 



(With plate IV.) 



I received last year from Major Sandeman, C. S, I., Political Superin- 

 tendent of Kelat, the head and horns of a sheep which he supposed to be 

 the same as the oorial {Ovis egcloceros) and which had been obtained in 

 the Hills above the Bolan pass. 



Directly I saw these horns I was struck with their greater length and 

 slenderness, and their peculiar twist, and after comparing them with two 

 specimens of O. Vignei, and numerous specimens of O. cycloceros, and the 

 descrij^tion of O. Gmelini, the head appears to me to belong to a hitherto 

 nndescribed species. 



In all these three species, as far as I can make out, each horn lies in 

 one plane, whereas in the present species the horn twists out, in a capital 

 S. fashion. There is in fact much the same difference between the horns 

 of the present species and of O. cycloceros^ that there is between those of 

 O. Kareleni, and O. Hodgsoni. 



It seems to me not impossible that this species may be one at any rate 

 of the wild stocks from which the domesticated breed originated. 



I propose to name this sheep 



OviS BLANFOKDI. 



after my friend Mr. W. T. Blanlord, our well known Zoologist and Geolo- 

 gist. 



The following are the dimensions of the skull and horns with corre- 

 sponding dimensions of those of a specimen of O. cycloceros, of apparently 

 the same age, viz., about 8 years. In the case of each measurement, the 

 dimension first given is that of O. Blanfordi.
