1865.] Note on Lagonys Curzoniea, Hodgson, 111 
Schreber.* The first never frequents a great elevation above the 
bottom of the valleys and is especially numerous in the neighbourhood 
of streams. Arctomys bobac (called by the Tibetans Phya) makes its 
very deep burrows mostly on the sides of the valleys and near their 
bottom; it ascends, however, the slopes of the hills in this portion of 
Ladak to a height of 17,800 feet. This greatest elevation, at which I 
observed it, was near the Samunda-la, south-east of the Chomoriri ; 
while the lowest was in the Para valley about 15,400 feet. It lives 
probably lower than this. 
L. Curzonie ranges, however, somewhat higher. I noticed it on 
the top of the Lanak pass at an eleyation of 18,672 feet, where only 
two minute plants existed, Stracheya Tibetica, Bth. and Capsella Thom- 
soni, Hf. both flowering in August.t It is found associated with 
Corcus tibetanus, Hodgs., Gyps fulvus, Gmel. and a new species of 
Procarduelis, among birds; an Argynnis, among butterflies and some 
common flies, forming the highest observed animal life in these 
hills. In fact it is difficult to design a limit to the height up to which 
L. Curzonie lives. I believe, it ranges as high as any trace of 
vegetation exists, which would be here about 19,000 feet, or very 
near it. Between the two given limits of the Para valley and 
19,000 feet, it is seen in great abundance all over the eastern portion 
of Ladak. It is certainly the species of Adams and Cunningham, as 
there is to my knowledge, no other Lagomys here, at least none so 
common. Its geographical range must extend farther to the east and 
south-east, as Mr. Hodgson obtained his specimens from the district 
of Chumbi, (north-west of Sikkim ?). I have not observed it Soura 
of the Bara-latse range, either in Spiti or in the south-eastern part 
of Lahoul, the Ohandra valley; although Phaiomys Cucurus does 
occur in both provinces and even in Kulu. In Spiti, Lagomys Curzo- 
ni@ is represented by the smaller L. Royle:, Ogilby, which there lives 
between 12,500 (above Lari) and 16,000 feet, but usually about 
13,000 feet. 
* Mr. Blyth (Cat. of the Mammalia of the Asiatic Museum, 1863, p. 109) unites 
and, I think, with good reason, Mr. Hodgson’s Arctomys tibetanwus and hemachas 
‘lanus, [Himalayanus was not used by the first author] as well as Arct, fulvus, 
Evers., with the species, which became first known through the travels of 
Pallas in Northern Asia, and which Schreber named A. bobac. 
+ Dr. Thomson (Travels, p. 144) mentions three plants on the Lanak pass, a 
little Arenaria or Stellaria and two Cruciferz,
