Remarks: Even though Torit is quite some distance removed from 

 both tlie Atbara River and Khartoum, tlie tl)ree specimens from there 

 are identical in color with the type from Atbara. Unfortunately, the 

 skulls of both of the Torit specimens are badly broken, but what is 

 left of them agrees very well with the type of C. pasha.

Crocidura luirella Heller, Smithsonian Mi;sc. Coll., vol. 56, No. 15, p. 4, Dec. 23, 

 1919. (Rhino Camp, Lado Enclave.) 



Specimens Examined: Three, from: Mongalla, 2 (BM); Rhino 

 Camp, 1. 



Measurements: An adult male from Mongalla measures as follows: 

 Length of head and body 75; length of tail 41 ; length of hind foot 1 1 ; 

 length of ear 10; condyloincisive length of skull 20.9; greatest breadth 

 of cranium 8.9; maxillaiy breadth 6.8; length of palate 8.7; length of 

 upper toothrow 9.0; least interorbital width 4.2, 



Remarks: C. luirella differs from C. aridula in a somewhat more 

 yellowish tone above and a decided huffier gra}^ below. The skulls 

 differ in that luirella is smaller in all measurements taken than is 

 aridula. In cranial proportions however, the two kinds agree. 



It is apparent that the relationships of aridula, luirella, and 

 marrensis are with sericea and each other; therefore, they are all 

 treated as subspecies of sericea, which is the oldest name for the group.

Crocidura hindei marrensis Thomas and Hinton, Proc. Zool. See. London, p. 252, 

 July 6, 1923. (Wadi Konger, east-central Jebel Marra.) 



Specimens Examined: Two, both in BM, from: Wadi Burar, 

 northwestern Jebel Marra, 1 ; Wadi Konger, east-central Jebel Marra, 1. 



Measurements: The measurements of an adult female from the 

 Wadi Burar are as follows: Length of head and body 83; length of 

 tail 58; length of hind foot 13; greatest maxillary breadth of skull 7.0; 

 length of palate 8.7; length of upper toothrow 9.4; least interorbital 

 width 4.3. 



Remarks: C. s. marrensis differs from C. s. lutrella in browner 

 color dorsally, darker, longer tail, and much huffier gr&j underparts. 

 The skulls are practically identical except for the interpterygoid fossa 

 in marrensis being more constricted posteriorly. Again, these char- 

 acters do not appear to be of more than subspecific value.
