110 MR. G. T. BETHUNE-BAKER ON NEW [Feb. 18, 



house's Lagomys ogotoma, the description of which was based on 

 this specimen, while the skull characters of the genus Ogotoma, as 

 given by Gray, were also drawn up from it. And it has been 

 ao-ain redescribed by Bonhote as Ochotona ogotona, and stated to 

 be nearly related to 0. ladacensis Giinth. 



The name 0. 2Jcdlasi and the descriptions above quoted will 

 therefore have to be reckoned with by future writers about this 

 difficult group. 



" ISTot common — somewhat diurnal. Frequents the hill-sides 

 where grows a stiff fi-agrant weed on which it seems to feed. In 

 several old fox-burrows I found great masses of cuttings of this 

 weed, and in that immediate vicinity trapped five of the series. 

 Their burrows are not clean-cut and vary greatly in diameter. 

 Where several of these animals live near together their holes 

 are connected on the surface by a network of little trails. The 

 presence of these animals is generally betrayed by little piles of 

 spherical droppings at the mouth of the burrow, indicating also 

 that the occupants are cleanly in habit." — M. P. A .

(5 . Both wings bright oi-ange-red. Primaries with term en 

 and apical half of costa linear, black, Avith all the terminal parts 

 of the veins outlined finely with black, tapering finer basewards ; 

 a black spot in the cell, another at the end of the cell, beyond 

 this three subcostal confluent small spots with a larger one shifted 

 outwards between veins 4 and 5 and a smaller spot below it 

 between 3 and 4, a spot below the end of the cell, two between 

 veins 1 and 2, one near the base and one near the termen. 

 Secondaries with costa narrowly black, with a subterminal scal- 

 loped line confluent with the costa along the veins, terminal part 

 of veins slightly marked with black, base irregularly restrictedly 

 black • a series of three subbasal spots, that in the cell shifted 

 slio-htly outwards, a spot at the upper end of the cell ; a curved 

 series of postmedial spots, that near the angle of vein 2 shifted 

 well inwards with one below it shifted well outwards. — Under 

 side. Primaries as above, but paler. Secondaries ochreous, with 

 pink internervular stripes ; the spots as above, but smaller, and 

 the base broken up into five or six spots instead of being all 

 confluent as above. 



2 . Both wings dirty brown, with smaller spots and no basal 

 spot in the fold of the primaries. Secondaries with the black
