rejerred to Ciicetulus phoeus and campbelli. 453 



combine them all (except a set from Ladak) as one species, 

 which, as shown above, should bear the name migra- 

 tor'ms. 



The status of the Grecian form, Cricelulus atlicus, and 

 that of Palestine, to which the name cinerascens* applies, 

 I do not propose at pj'csent to discuss, but 1 confess I doubt 

 very much if cither of them deserves specific distinction 

 from C. migratorius. 



Puttings aside these, the subspecies of C. migratorius 

 which may be recognized appear to be as follows : — 



C. migratorius migratorius, Pall. 



Synn. accedula, Pall., ^J/^(^^^5, Pall., eyerswanni, Brandt. 



Ti/pe-locality. R. Ural. 



Range. S. Russia, Caucasus region, Transcaspia, Persia, 

 and Asia Minor south of the coastal forest-regiou of the 

 north-east. 



Size comparatively small ; skull about 27 mm. in length, 

 its upper tooth-row 4 mm., the teeth themselves narrow 

 and light. Fur short, hairs of back about 9 mm. in length. 

 Colour above pale grey, generally with indistinct median 

 darker dorsal shading. Hairs of under surface with grey 

 bases, except that they are wholly white on an area on tlie 

 throat, which extends in a median point down to between 

 the fore legs. 



C. migratorius vernula, subsp. n. 



Type-locality . Khotz, near Trebizond. 



Range no doubt all the forest coastal strip along the 

 south-east corner of the Black Sea. 



Size averaging slightly larger than in true migratorius^ 

 Fur of back 8-9 mm. in length. Colour darker through- 

 out, the upper surface near " mouse-grey," the median dark 

 dorsal area faintly evident. Plairs of under surface with a 

 shorter length of white above the slaty, and the white itself 

 not so pure, but faintly suffused with buffy ; white throat-area 

 less extended towards the chest, ending about halfway 

 towards the fore limbs. Ears with proectote markedly 

 blackish. Tail distinctly darker above, at least for its basal 

 half. 



Dimensions of type : — 



Head and body 115 mm. ; tail 32; hind foot 17; car 17"5. 



Skull : greatest length 28"2 ; condylo-incisive length 26 ; 

 palatal foramina 5 ; upper molar series 4 2.
