conspicuously smaller size of the eai's, these being only 1 1 mm. in 

 the island species and 17 in iS. zenkeri. The skulls, judging only 

 by Dr. Matschie's description, seem closely similar. 



The cheek-tooth foi-mulfe of Scotonycteris and Epomophorus ai'e 

 considei-ed by Dr. Matschie to be P. |, M. |, and that of Cynopterus 

 to be P. f , M. 1^ ; but the study of a young specimen of the last- 

 named genus shows that Dobson was perfectly right in giving its 

 formula as P. f, M. | *. This young specimen has milk-premolars 

 present above the second and third cheek-teeth in each jaw, thus 

 showing them both to be premolars ; the minute anterioi- tooth 

 has, as usual, no predecessor. 



It would follow from this that the formula in Scotonycteris is 

 P. f, M. I, the same as that rightly determined for Epomophorus 

 by Dobson. 



But f ui'ther, while correctly determining the teeth of Cynopterus, 

 Dobson does not seem to have realized that the same formula, 

 P. f, M. 4, would certainly be applicable to Nyctymene t (" ^«r- 

 pyia"), to which he assigns P. |, M. -f. 



In Dohsonia, on the other hand, with the same total number of 

 four cheek-teeth in the upper jaw, the tooth lost has obviously 

 been the anterior premolai- instead of the last molar, so that the 

 formula should be, as Dobson puts it, P. |, M. f . Matschie 

 erroneously gives it as P. -I, M. f.
