butleri which does nob fit in the group called Hscheri on any cranial or 

 morphological feature. 



Without examining all of the specimens extant and the references 

 to all the types available, this hypothesis is at best a mere suggestion. 

 Where specimens have been studied and found to agree in what appear 

 to be specific characters they have been placed as a subspecies of that 

 particular species. 



Again, this arrangement is based only on the shrews from the Sudan 

 and on specimens immediately adjacent geographically, so that the 

 suppositions and allocations may not be the best, but certainly it 

 shows the relationships of these mammals better than Dollman's 

 revision. 



There are three names from the Sudan in this genus that are not, at 

 this time, certainly identifiable. They are C.ferruginea Heuglin 1865, 

 from ''Lande der Ridj-Neger," C. julvastra Sundevall 1843, from 

 Bahr-el-Abiad, and C. fusco-murina Heuglin 1865, from Meshra-el- 

 Rcq. Dollman, in his revision of the African members of the genus, 

 is not sure of what they are or to what they may be related. For the 

 purpose of this paper these names are considered as unidentifiable. 



One specimen, CNHM 73890, is, at this time, not identifiable. It 

 is far darker than anything known from the general region but has a 

 skull which in many ways resembles that of C. turha. Since there is 

 only the one specimen I prefer leaving it as indeterminate until more 

 material from the Lokwi region is obtained. 



Crocidura bicolor tephragaster, new subspecies 



Type: Museum of Comparative Zoologj^, No. 44773, adult male, 

 skin and skull, from Torit, Anglo-Egyptian Sudan. Obtained Apr. 

 25, 1950, by J. S. Owen, original number 1158. 



Specimens Examined: Eighteen, from Torit (8, MCZ). 



Diagnosis: General over-all dorsal color near Mummy Brown, 

 shading over sides to Light Mouse Gray of the belly; hands and feet 

 lighter than the dorsal color; tail dark brownish black well covered 

 with bristle hairs. Skidl large for the species, relatively wide across 

 the maxillaries, upper teeth relatively massive, rostrum relatively 

 short and broad. 



Measurements of the Type Specimen: Total length 112; length 

 of tail 47; length of hind foot 11; length of ear 4; condyloincisive 

 length of skull 17.4; greatest breadth of braincase 7.2; gi-eatest 

 maxillary breadth 5.2; length of palate 6.1; length of upper toothrow 

 7.3; least interorbital width 3.5. 



Comparisons: From the type of C. b. cunninghamei, C. b. tephra- 

 gaster differs in: Color lighter, that is, there is more gray and less
