length of tail 61, 61; length of hmd foot 17, 17; length of ear 12, 13; 

 condyloincisive length of the skull 29.1, 28.0; greatest breadth of 

 skull 12.7, 11.7; greatest maxillary breadth 9.2, 9.1; length of palate 

 12.6, 12.1; length of upper toothrow 12.3, 12.6; least interorbital 

 width 5.2, 5.2. 



Remarks: Crocidura darfurea is a lighter colored form of C. 

 ny ansae. There is no criterion on the skull or skin to warrant the 

 recognition of C. darfurea as a full species. It is in all respects 

 another nyansae. It is larger and somewhat paler than C. n. sururae 

 and larger and decidedly paler than typical C. nyansae.

Crocidura sururae Heller, Smithsonian Misc. Coll., vol. 56, No. 15, p. 2, Dec. 23, 

 1910. (Rhino Camp, Lado Enclave.) 



Specimens Examined: Eleven, from: Bor, 2 (BM); Mongalla, 1 

 (BM); Malelc, 3 (BM); Up'per Nile, 1 (BM); Loa, 18 miles north of 

 Nimule, 3 (MCZ) ; Nimule, 1 (MCZ). 



Measurements: The measurements of the type, an adult male, 

 are as follows: Length of head and bod}^ 111 ; length of tail 64; length 

 of hind foot 17; cond3doincisive length of skull 28.5; breadth of 

 braincase 12.0; length of upper toothrow 13.0. 



Remarks: All of the above specimens are darker than in the 

 original series from Rhino Camp. The skulls, however, show no 

 variation from the type series. 



There are no characters of either the skin or the skull in this series 

 which warrant the separation of sururae as a full species. There is 

 a specimen from Butiaba, Uganda, which shows rather intermediate 

 characters between nyansae and the present form, so it is considered 

 best to refer the above specimens as subspecies of the previously 

 named nyansae. 



This is a case in which it is possible that Loring collected on the 

 east bank of the Nile. The type localit}^ for sururae is at Rhino Camp, 

 which is on the west bank, yet specimens there are found to be iden- 

 tical from Mongalla and Malek.
