1908.] MAMMALS FROM NORTH CHINA. 637 



of Shan-si Province, and on 31st October left that city for the 

 mountain- range some 15 miles west of there. 



" At this point, at an altitude of 5400 feet, I found the 

 mountains sparsely covered with pine trees and the canyon sides 

 overgrown with dense bushes. 



"On 17th ISTovember I began work at Chao-Cheng-Shan, a 

 mountain of 10,000 ft. altitude, situated about 100 miles west- 

 north-west of Tai-Yuen-Fu. There, at an altitude of 8000 ft., 

 1 made my home in a peasant's hut. Above me extended a 

 dense forest of spi-uce and hemlock, below I overlooked the 

 rugged bare hills and cultivated valleys characteristic of North 

 China. 



"I remained in this place till Dec. 6th, 1907. The weather 

 throughout was fiercely cold, as a north wind blew almost 

 unceasingly. 



"On December 27th I went eastward of Tai-Yuen-Fu about 

 20 miles to a temple wood among the ' loess ' hills. But this 

 proved such a poor collecting-ground, and the weather so very 

 cold, that on 4th January I thought it advisable to return to 

 the city." 



1. Rhinolophus ferrum-equinum NIPPON Temm. 



J . 1571. Cave 30 miles W. of Peking. 600'. 



This and the two following species were obtained in a sacred 

 cave which Mr. Anderson might not have been allowed to enter, 

 certainly not to shoot in, had it not been for the kind offices of 

 Dr. J. H. Ingram of Tung-chou, who persuaded the priest of the 

 cave to allow him to do so. Gi-eat numbers of bats were hanging- 

 from the roof, but besides the one Rhinolophus, which was caught 

 low down within reach, and the two specimens of Myotis, all 

 proved to belong to one species, a Miniojyterics . 



2. Myotis (Leuconoe) pequinius, sp. n. 



c? . 1573, 1589. Cave 30 miles W. of Peking. 600'. 



A comparatively large Leuconoe, with a fringed interfemoral 

 membrane. 



In size one of the largest species of the group, exceeding all the 

 Old-Woi'ld species of Leuconoe, except M. ricketti. Fui- rather 

 short and velvety, hairs of back about 5 mm. in length. General 

 colour above uniform " drab-grey," the bases of the hairs slaty. 

 Under surface whitish grey, the ends of the hairs neaily white, 

 their bases slaty ; under side of hind legs and the anal I'egion 

 edging the membranes white and practically hairless. Ears of 

 mediiim size, rather narrow, concave on their external border ; 

 tragus about half the length of the ear, narrow, not sharply 

 pointed, slightly curved outwards above. Wings attached to the 

 lower end of the tibise. Feet of average Leuconoe proportions. 

 Interfemoral membrane fringed jDosteriorly with pale buffy hairs ; 

 tip of tail not projecting from the membrane, so far as can be
