XXIV. — On Two neio Mammals from China. 

 By Oldfield Thomas, F.R.S. 



In a further consignment of Chinese mammals, presented by 

 Mr. F, W. Styan, with liis customary liberality and patriotism, 

 to the National Museum, there are examples of the following- 

 new bat and new water-shrew, the former needing distinction 

 as a new genus : — 



Ia, gen. nov. {Vesjyertih'omdce) . 



General characters of Vespertilio, but dental formula as in 

 Pipistrellus. Size very large. Hind claws disproportionally 

 long. 



Outer upper incisor minute; inner long, thick, bicuspid 

 terminally. Small upper premolar exceedingly minute. 

 Molars comparatively simple, the minute outer supplementary 

 cusps scarcely developed, and the large inner cusp without a 

 smaller cusp on its hinder base. Lower incisors trifid, over- 

 lapping. Lower premolars not markedly crushed, the ante- 

 rior about half the height of the posterior. Lower molars 

 with the middle one of the three inner cusps markedly higher 

 than the other two ; last molar with its posterior talon small, 

 about half the area in section of the main portion. These 

 tooth-characters are all approximately as in the Serotine 

 group and different from what is found in Pipistrellus. 



Skull short and powerful, not flattened; with a large 

 crested and overhanging occipital " helmet," exceeding that 

 of the Serotine. 



Proportions of ears, tragus, and digits about as in the 

 Serotine, but the hind claws disproportionally long. No 

 postcalcareal lobule.
