4C8 Mr. O. Thomas on 



8. Ilipposideros cqfer, Sund. 

 996, 997, 1078, 1251, 1252, 1296-1300. Poko, Welle. 



9. Nycteris grandis^ Pet. 

 1351. Poko. 



10. Nycteris hispida, Schr. 



818. Medje. 



1311, 1372, 1401. Poko. 



11. ScotopJiilus nux, TIios. 



739, 740. Medje. 



The conspicuous difference between the colour of S. nux 

 and tliat of all forms of S. nigrita makes me now think that 

 it should be recognized as a distinct species, and not merely 

 a subspecies of the older known form. 



These specimens show no difference from the type, which 

 was collected by Mr. Bates at Efulen, Cameroons. 



12. Otomopa mcirtiensseni, Matsch. 



1290. Poko. 



Only hitherto known by the type in tlie Berlin Museum. 



As I expected when describing 0. wroughtoni, this African 

 Otomops is quite remarkably similar to its Indian relative. 

 All the important skull-characters marking the genus 

 Otonwjjs are quite the same, even to the peculiar vertical 

 plate on the zygomata. 



In colour, however, there is quite sufficient difference to 

 leave no doubt that the two forms are specifically distinct. 



[Although not a part of the Cliristy collection, the follow- 

 ing interesting bat, being from the same region of the Congo, 

 may be here described. Most unfortunately, it is without the 

 skull, but the structure of its ears and muzzle leave me in 

 little doubt as to its affinities. 



These would appear to be with the bat hitherto knoM'n as 

 JEomops whitleyi, hut Mr. Miller has made out so strong a case 

 for the generic identity of Eomops with the far earlier Myo- 

 pterus, Geoff., that 1 am prepared to accept it until such 

 time as the capture in Senegal of a bat corresponding with 

 Daubenton's description confirms or upsets Mr. Miller's 

 hypothesis.
