308 Mr. O. Thomas on Two new 
XXXIT.—On two new Rodents from Van, Kurdistan. 
By OLpFIELD THOMAS. 
Tue British Museum owes to Major W. H. Williams, 
recently H.M. Consul at Van, Kurdistan, Eastern Asia 
Minor, a collection of small mammals made in the neigh- 
bourhood of that place. Besides many other specimens of 
interest to mammalogists, there are examples of the two 
following new species :— 
Ellobius lutescens, sp. n. 
Size medium. Fur long and loose, not so close or sleek 
as in the other species. General colour dull slaty buff, quite 
different from the bright yellowish of the Eastern species, 
with which it agrees in tooth-structure, and more similar to 
dark examples of H. ta/pinus trom the Volga. Head but 
little darker than body. Belly scarcely lighter than back, 
the line of demarcation quite gradual. Everywhere, above 
and below, the hairs are dark slaty grey with buffy tips. 
Skull with a long slender muzzle. Nasals long and very 
narrow, much compressed for their posterior two thirds, 
Zygomata boldly expanded, starting out anteriorly at a right 
angle to the general line of the skull. Lambdoid crest 
curving forwards mesially, not forming an angle in the 
middle line. Posterior palate much as in L. fuscocapillus, 
but inner part of bulle rising much higher above the level 
of the basioccipital and basisphenoid than in that species. 
Teeth apparently as in L. fuscocapillus, the complicated 
shape of the last upper molar quite as in that species*, and 
aaa similar in all the six specimens obtained by 
ajor Williams. 
Dimensions of the type, an adult female, measured in flesh 
by collector :— 
Head and body 125 millim.; tail 14; hind foot 22. 
Skull: basal length 31; basilar length 28; greatest 
breadth 24 ; nasals 10x3°4; palate, length from henselion 
18°7; diastema 12; length of upper molar series 7:2. 
Hab. Van, alt. 5000 feet. 
Type. B.M. no. 97.6.4.17. Collected April 12, 1897. 
This Ll/obius is very distinct from any previously de- 
scribed. From the group containing L. talpinus, Tancret, 
and rufescens (stated by Biichner to be all identical), it 
differs by the structure of its last upper molars, which are 
as in HL. fuscocapillus. From the latter again, as from the 
* Figured by Blanford, J. A. 8. B, 1. pt. 2, pl. ii. (1881).
