and the other occurs over the whole of Africa. The same sort of 

 thing is the case with the other specimens. 



In this part of the new British Territories, therefore, we seem to 

 possess a region of exceptional zoological interest, as being the 

 meeting-place of the North-eastern, Western, and Southern faunas ; 

 and it is much to be hoped that under the auspices of the Imperial 

 British East-African Company other naturalists will follow Mr. 

 Jackson's spirited example, and that we shall thereby gain a thorough 

 knowledge of the manner in which the different zoological districts 

 pass into one another within our " sphere of influence." 



The collection consists of 38 specimens, referable to 15 species, 

 of which three, two Rodents and a Bat, are new to science'. The 

 forms mostly belong to groups so obscure zoologically, and so trouble- 

 some and difficult of collection under the trying circumstances in- 

 separable from such an expedition, that Mr. Jackson deserves the 

 sincere thanks of zoologists for this material contribution to our 

 knowledge of the smaller Mammals of Africa. 



1. Herpestes gracilis, Riipp. 

 a. One specimen. 



2. Petrodromus tetradactylus, Ptrs. 



a. S . One specimen. 



3. Crocidura hedenborgi, Sund. 

 a. Mianzini. 8/89. 



4. Epomophorus minor. Dobs. 

 a-c. Turquel, Slik. 1/90. 



This rare species has been obtained at Zanzibar and Bagamoyo, 

 and also, by Dr. Emin Pasha, at Kiriamp, just south of the Albert 

 Nyanza. 



5. Nyctinomus lobatus, sp. n. 



a. S • Turquel, Silk. 1/90. Type. 



Allied to N. cestoni, Savi ", or rather iV. tcBniotis, Raf.\ as it ought 

 to be called, and to N. africanus, Dobs. ; but distinguished from both 

 by its larger ears, larger tragus, higher antitragas (fig. p. 183), and 

 coloration, while in other respects it agrees sometimes with one 

 and sometimes with the other, and forms in some respects a con- 

 necting-link between them. 



Ears very large, rounded, laid forward they extend quite a quarter 

 of an inch beyond the tip of the muzzle ; their inner bases united on 

 the muzzle; their substance comparatively thin and transparent; 

 keel of the conch scarcely thickened below ; antitragus very high
