This fine bat 1 had formerly supposed to be referable to 

 ri})istrellns offinis, Dobs., of which the only recorded S[)eei- 

 nien is iii Calcutta ; but Dobson's measurements of the digits 

 show that that is really a Pi/ifslrellus, not a ^ijctalus. 



The known species of Sijctalus differ, inter se, by hardly 

 any characters but size, so tliat the distinctions in tragus, 

 skull, and dentition above detailed indicate that the present 

 bat is more distinct fiom any of them tliau they are from 

 each other. 



The species is named in honour of General Joffre, 

 Commander-in-Chief of the French Army. 



Tylonycteris. 



While the forearms of the members of the genus Ti/lo- 

 rtycteris are all very nearly of the same length (2U-29 mm.), 

 the skulls show a considerable diversity in size, and it is 

 quite evident that several different species or subspecies 

 should be recognized. Moreover, the forearms do not vary in
