OX SOME MAMMALS OBTAINED BY THE HOX. X. CHARLES 

 ROTHSCHILD, FROM OKiXAWA, LIU-KIU ISLAXDS. 



By J. LEWIS BONHOTE, M.A. 



THE Liu-Kiu Islands have, so far as tbeir Mammalia are coucenied. hardly 

 been worked at all, so that the small collection brought home from Okinawa 

 bv the Hon. N. Charles Rothschild form a welcome addition to our knowledge ot 

 its fauna. The collection only contains five species, two of which appear to be 

 uudesci'lbed, while the remaining three have all been previously recorded. A set 

 has been presented to the National Collection, and the remainder are in the 

 >ruseum at Tring. 



There have hitherto only been four papers dealing with the jMumnials from 

 these Mands, viz. :— 



Pterojnis keraudrenl \ar. loochooensis Gray. Cai. Monk, ami Fruit-eat in;/ 

 Bats, p. 106 (1870^^. 



On the Fauna of (»kinawa. A. Fritze. Zool. J. B. Syst. vii. p. 851 (1894).

The whole of the present collection came from the island of Okinawa, aud 

 were collected March 1902. 



1. Rhinolophus minor (Horsf). 

 Four specimens, '2 6 6 and 2 ? ? . 



2. Miniopterus fuscus sp. nov. 



Three specimens, 1 6 and 2 ? ?, obtained on March 18. iy(»2. 



A small and dark island form of 'Minioptervs. 



General colour throughout dark sooty-brown, each hair being miitorin in i-olour 

 along its whole length. 



In general size <,md shape it resembles tiie other species of the genus appi'oaching 

 in size most nearly to M. jntsillus of the Nicobars. It is slightly sniallcr tlian 

 several .lapanese specimens with whii'h I have compared it, but is aliout the sanir 

 size as some from Anioy. 



The skull may be characterised at once by its much smaller size. It does 

 not rise up in the frontal region nearly so abruptly, but rises up from the muzzle 

 in a more gradual slope. In other respects it does not greatly differ from skulls 

 from Fokien and India. 



Dimenisions of type. Total expanse 210 mm.; forearm 44, hiudfeet 9, ear 9.
