Family HYSTRICIDAE 



Genus ACANTHION F. Cuvier 



ACANTHION SUBCRISTATUS (Swinhoe) 

 Eystrix suicristaia Swinhoe, Proc. Zool. Soc. London, 1870, p. 638. 



/Specimen. — One from Siiifii, Szecliwan. 



This specimen, the only Chinese porcupine in the National collec- 

 tion, is a juvenile, with flat skin and broken skull, but on the strength 

 of the relatively long nasals, v\'hich extend much farther back than 

 opposite the anterior border of the orbit. I venture to class it with 

 the species of eastern China, rather than with yunnannensis. 



Order LAGOMORPHA 



Family OCHOTONIDAE 



Genus OCHOTONA Link 



OCHOTONA (OCHOTONA) DAUURICA DAUURICA (Pallas) 



Lepus danuricus Pallas, Reise, vol. 3, 1776, p. 692 (Mongolia). 



Specimens. — Eight from Tabul, Chihli, 



This series, in summer pelage, is of very uniform coloration. 



OCHOTONA (OCHOTONA) DAUURICA ANNECTENS Miller 



Ochotona annectens Miller, Proc. Biol. Soc. Wash., vol. 24, 1911, p. 54 

 (Chingningchow, Kansu, China). 



Specimens. — Seven from Kansu : 15 miles northeast of Chingning- 

 chow, 6, including the type; 116 miles east of Lanchow, 1. 



As compared with available hedfordi the skull differences of 

 aniiectens are too slight to be of great value in diagnosis. The body, 

 and especially the hind feet, of the latter are the smaller, however, 

 and the coloration is a faint shade darker. Where the above speci- 

 men was secured east of Lanchow, Sowerby found that the animals 

 had their burrows in the (presumably rather bare) sides of the small 

 guUies in loess gulches. 



OCHOTONA (OCHOTONA) DAUURICA BEDFORDI Thomas 



Ochotona hedfordi Thomas, Ab.st. Proc. Zool. Soc. London, 1908. p. 45 (Ning- 

 wufu, Shansi, China). 



Specimens. — Seven: Wutsai, 3, and 30 to 50 miles northwest 

 of Taiyuanfu, Shansi, 3 ; and 12 miles south of Yenanfu, Shensi, 1. 



These are in full winter pelage, being in color very similar to 

 dauurica typicus but paler. The one from near Yenanfu is grayer. 

 Sowerby found the burrows usually in very dense scrub where the 

 sharp-thorned wild jujube afforded protection from enemies.
