A NEW BAT FROM TONKIN. 

 BY GLOVER M. ALLEN. 



Among a small collection of mammals lately acquired by the 

 Museum of Comparative Zoology, is a specimen of the genus 

 Harpiocephalus from Tonkin, eastern Indo-China, which I am 

 unable to refer to any of the described forms. Mr. G. S. 

 Miller, Jr., in 1907 (Bull. 57, U. S. Nat. Mus., 1907, p. 230), 

 restricted the genus to include the single species H. harpia 

 (Temminck) of India and the Malay region. The type locality 

 of Temrainck's Vespertilio harpia is Java, and through Mr. 

 Miller's kindness I have been able to examine a fine skin and 

 skull from Buitenzorg, obtained in 1909 by the Owen Bryant 

 Expedition to Java. Compared with the Tonkin specimen 

 tbis is a larger and much more brightly colored bat with the 

 belly nearly gray instead of reddish. In their paper on 

 mammals from Western Java, Messrs. Thomas and Wroughton 

 (Proc. Zool. Soc. London, 1909, vol. 1, p. 380), record speci- 

 mens from that island and remark that 'the Himalayan 

 form is obviously different by its darker and more chocolate 

 colour. It should bear the name of" H. lasyurus (Hodgson), 

 the type of which, from Dajiling, Nepal, is in the British 

 Museum. They add that ' Horsfi eld's Lasiurus pearsoni, 

 also from Dajiling, would be a synonym of it." I have 

 been unable to examine this species, but Hodgson describes 

 it as "bright rusty above, sooty below, the hairs tipped with 

 hoary." Apparently it is even larger than the Javan species 

 as Jerdon (Mammals of India, 1874, p. 41) gives the forearm 

 length 2i inches (57 mm.), though Dobson (Cat. Chiroptera, 

 1878, p. 282), in an alcoholic female from the Malabar coast 

 found it but 2 inches (51 mm.), and Blanford (Fauna of 

 56— Proc. Biol. Soc. Wash., Vol. XXVI, 1913. (213)
