470 Mr. 0. Thomas on 



Original number 17. Congo Museum, no. 2911. 



The coloration of this beautiful bat is quite unique, but of 

 course it assimilates, in the brown upper and white lower 

 surface, with that of M. daubentoni and whitleyi.~\

1206. Toko. 



All essential characters as in true P. velox of the Lower 

 Congo, Gaboon, &c., but the white of the underside more 

 extended, reaching higher up on the sides, where also the 

 brown hairs are prominently tipped with greyish white. 

 Fore limbs whitish, almost wholly in the whitish area. 

 Sides and under surface of hairy base of tail silvery white, 

 nearly wholly brown in velox. 



Hind foot of no. 763, the type, 40*5 mm.

15. Crocidura sururce, Hell. 



890. Viadama, Welle. 



949. Poko. 



949 is quite like examples from Wadelai and others from 

 the Alexandei -Gosling Expedition determined by Mr. Dull- 

 man ; 890 is rather darker. 



16. Crocidura poensis attHa, Dollm. 

 807, 812, 854, S5S, 866, 873. Medje, Welle. 



17. Scutisorex congicus J sp. n. 



<J. 840. Medje, Upper Ituri, 17th April, 1914. 



Skull smaller than in 8. somereni } and colour more suffused 

 with buffy. 



General appearance and coloration quite as in S. somereni, 

 except that the fur is more suffused with buffy or isabella, 

 but even this difference is not unlikely to be individual or 

 sexual. Fur slightly shorter and harsher than in the allied 

 species.
