OCHOTONA WARD! Bonliote. 



Ochotona loardi Bonhote, Abstr. P. Z. S. 1904, No. 10, p. 13, 



E'ov. 22. 



In the summer pelage, worn from June to September, the whole 

 of the head, shoulders, and fore pai-t of the body (excepting a 

 small patch behind the ea.i's, which is white) is bright chestnut 

 (cinnamon-rufous, Ridgw.), becoming more vinaceous on the throat. 

 The remainder of the upper parts is dark greyish rufous, each 

 hair being black at its base with a light subterminal annulation, 

 the tips being either dark or rufous. This latter colour encroaches 

 greatly on the light poi'tion often to its total exclusion, especially 

 on the sides of the body. The under parts are white lightly 

 washed with pale buff. The feet are of the same colour. Ears 

 moderate in size, very scantily clothed with hair. 



In the winter pelage this animal is of a unifoi-m dark iron-grey 

 all over, with the exception of the light patches behind the ear, 

 which are white as in summer. Under parts dull white. Slight 

 traces of rufous are generally to be found at the base of the 

 shoulders, on the crown of the head, and along the flanks. The 

 young i-esemble the adults in winter, but ai'e slightly browner in 

 general colour and have the rufous on the head and shoulders 

 more marked. 



The skull is very similar to that of the type of 0. roylei, as 

 figured in the original description, and does not show any great 

 features of note. The combined foramen, while having the narrow 

 anterior third and the slight constriction typical of the rtffescens 

 grovip, shows a tendency for the constriction to become less 

 marked, but it can nevertheless be eleaiiy made out in every 

 example. 



Dimensions of type in flesh. Head and body 187 mm. ; hind 

 foot 25 ; ear 22-5. 



Skull. Greatest length 44 mm. ; basal length 37 ; palatal length 

 17; length of foramen 12; zygomatic breadth 21; interorbital 

 breadth 5 ; breadth of brain-case 17 ; length of molar series 9. 



Habitat. Talien, Kashmir, 11,000 feet. 



Type (in Coll. Brit. Mus.). A. E. W. No. 56. Ad. 6 . Collected 

 on the 8th August, 1903. 



In external appearance this species most nearly resembles 

 0. roylei ; the latter, however, is much darker and lacks the 

 conspicuous white patches behind the ears. 



Ochotona curzoni^e Hodgs. 



Lagomys curzonioi Hodgs. (?iec Stoliczka) J. A. S. B. xxvi. p. 207 

 (1858); Gunth. Ann. Mag. Nat. Hist. ser. 4, xvi. p. 230 (1875); 

 Blanford, Fauna Br. Ind., Mamm. p. 457 (1891). 



This is the first species of the group which I have called after 

 it and which is very closely related to the rufescens group. The 

 difference between the palatal foramina of the two is well shown 

 by a comparison of the figures of 0. kosloivi (Biichn, Mamm.
