AET. 1 MAMMALS FROM CHINA — HOWELL 57 



Genus RHOMBOMYS Wagner 



RHOMBOMYS OPIMUS NIGRESCENS (Satunin) 



Oerbillus opimus nigrescens Satunin, Ann. Mus. Zool. Acad. Imp. Sci. St. 

 Petersb., vol. 7, 1903, p. 560 (Oroknor, central Mongolia). 



SpeciTTiens. — Nine from 45 to 105 miles northwest of Ninghsia, 

 Kansu. 



The validity of this race has not definitely been established and I 

 have not the material to settle the question, but these specimens fit 

 the description admirably. 



Genus APODEMUS Kaup 



APODEMUS AGRARIUS COREAE Thomas 



Apodemus agrarins coreae Thomas, Proc. Zool. Soc. London, 1908, p. 8 (Ming- 

 yong, 110 miles southeast of Seoul, Korea). 



8 specimens. — Five from 65 to 75 miles northeast of Peking, Chihli. 

 These are not greatly different from A. g. Tnantchuricus but aver- 

 age duller, with black stripe narrower. 



APODEMUS AGRARIUS MANTCHURICUS (Thomaa) 



Mus agrarius mantchuricus Thomas, Proc. Zool. Soc. London, 1898, p. 774 

 (Manchuria). 



Specimens. — Forty-four from Manchuria: 60 miles southwest of 

 Kirin, 21 ; 120 miles northeast of Sansing, 6 ; 180 miles up the Yalu 

 River, 2; Fengtien, 2; and Imienpo, 13. 



It is by no means certain that the Yalu River examples should not 

 be called coreae. 



APODEMUS AGRARIUS NINGPOENSIS (Swinhoe) 



Mus ningpoensis Swinhoe, Proc. Zool. Soc. London, 1870, p. 637 (Ningpo, 

 Chekiang, China). 



jSpecimens. — Forty-eight: Yochow, Hunan, 37; Taiping, Anhwei, 

 4; Nanking, 5; Chinkiang, 1; and Shanghai, Kiangsu, 1. 



In typical immatures there is quite a strong black dorsal stripe, 

 but not to the extent occurring in true agrarius. In the Anhwei adults, 

 however, there is but the faintest indication of this stripe, while in 

 the Hunan examples it is a bit better defined, though still faint in 

 all but two. Coloration is both pale and dull, with pelage short and 

 having less of the grayish ticking exhibited by palUdior. 



APODEMUS AGRARIUS PALLIDIOR (Thomas) 



Apodemus agrarius palUdior Thomas, Proc. Zool. Soc. London, 1908, p. 7 

 (Chefoo, Shantung, China), 



Specimens. — Eight: Near Tientsin, Chihli, 2; 15 miles south of 

 Sianfu, 3, and Yenanfu, Shensi, 3.
