point. Sowerby found it to inhabit the open, grassy hillsides clear 

 to their tops, at 9,500 feet. 



MICROTUS (PHAIOMYS) BRANDTI (Radde) 



Arvicola hrandti Radde, Mel. Biol. Acad. St. Petersb., vol. 3, 1861, p. 683 

 (Mongolia). 



Specimens. — Six (including the type of M. warringtoni) from 

 Tabid, Chihli. 



With access to a series of virtual topotypes of hrandti^ G. M. Allen 

 (1924) found that the size of the latter is fully as great as of the 

 specimens upon which G. S. Miller based his description of M. w<tr- 

 Hngtoni. As size was the only racial character ascribed to the lat- 

 ter, I follow Allen's example and list all these specimens under the 

 name 'b7'andti. 



MICROTUS (NEODON) IRENE Thomas 



Microttis Irene Thomas, Abst. Proc. Zool. Soc. London, 1911, p. 5 (Tatsienlu, 

 Szechwau, China). 



Specimens. — Two from Szechwan; Shuowlow, 1, and 10 miles 

 south of Tatsienlu, 1, 



Although these specimens differ from one another in several re- 

 spects, they are both assigned to this species for the present. 



MICROTUS (STENOCRANIUS) ANGUSTUS Thomas 



Microttis angustus Thomas, Proc. Zool. Soc. Loudon, 1908, p. 108 (about 100 

 miles northwest of Kalgan, Chihli, China). 



Specimens. — Four from Tabul, Chihli. 

 These are virtual topotypes. 



MICROTUS CALAMORUM CALAMORUM Thomas 



Microtus calamorum Thomas, Ann. Mag. Nat. Hist, ser. 7, vol. 10, 1902, 

 p. 167 (near Nanking, Kiangsu, China). 



Specimens. — Twenty from Yochow. Hunan. 



There is some resemblance of this large vole to M. ptUiceus. as 

 already pointed out by Thomas, but the relationship is hardly nearer 

 than specific. Hoy found many nestling young in early June, and it 

 is gathered from his field catalog that this species inhabits fairly dry 

 fields as well as the rushy growths of swampy areas. 



MICROTUS CALAMORUM SUPERUS Thomas 



Microtus calwrnorum superus Thomas, Abst. Proc. Zool. Soc. London, 1911, 

 p. 27 (30 miles south of Fenghsiangfu, Shensi, China). 



Specimen. — One skull only from Taipingsha, Shensi.
