45. Cricetus songarus. 



Has been observed almost all over Turkestan, except in the 

 Zarevshan districts and the neighbourhood of Hodgent ; it is 

 more an inliabitant of the lower altitudes, to which it appears 

 to keep the whole year round. 



46. Cricetus Eversmanni. 



Has been obtained about Issik-kul in the larch-wood and 

 apple-tree district. 



47. Cricetus accedula (sec. Eversra., e coll. Karel.). 



Occurred at the same place as the preceding species, but on 

 a lower-situated plain. 



I do not describe here the well-known Criceti of Turkestan 

 [C. songarus, C. Eversmonni, C. accedula)^ , hut will mention 

 a new species discovered, although it does not belong to Tur- 

 kestan. 



[^Cricetus murinus, sp. n. 



Belongs to the genus Cricetus, as proved by its cheek- 

 pouches {sacci huccales), but does not at all resemble the hamster 

 in outward appearance. The form resembles that of the mice ; 

 the body is tolerably slender ; the tail measures half of the 

 length of the body, the head included ; the colour and size 

 are like those of Arvicola arvalis, viz.: — length from the tip of 

 the nose to the root of the tail about 3^ inches; tail 1| inch, or a 

 little longer ; the colour above is gi-eyish dark brown, below 

 ash-colour. Only two specimens are known to me : — the one 

 which I caught in August 1857 on the steppe grass of the 

 summit of Ori, and presented to the Museum of the Academy 

 of Moscow ; and the second is in M. Gluch's collection at 

 Sarepta, near which place it was obtained : both specimens 

 are preserved in spirits. The latter was marked Arvicola 

 arvalis ; and I had my attention drawn to it by the long ears, 

 which are half as long as the head, whilst the ears of the 

 true Arvicola arvalis are much shorter and almost hidden by 

 the fur. Then I looked for the cheek-pouches, which I found. 



On account of its resemblance to Arvicola arvalis, this 

 little beast is easily overlooked. The collector ought to look 

 out for the combination of murine ears with the form and 

 colour of ^. arvalis ; and in such specimens the cheek-pouches

 Blanford from Ea.?tern Turkestan, Joum. Asiat. Soc. Beng. xliv. p. 108.
