MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 459 



browp. The skull has a wider braincase, generally shorter palate, 

 shorter upper tootlirow and a narrower interorbital region. 



C. h. tephragaster differs from the type of C. b. woosnami in the 

 skull being larger in all measurements taken. No color can be 

 compared inasmuch as the body of the type of woosnami is preserved 

 in alcohol. 



From the type of C. b. elgonius, C. b. tephragaster differs in: Color 

 about the same but slightly paler in the new form. Hind foot longer; 

 skull larger in all measurements taken. 



From the type of C. b. planiceps, C. b. tephragaster differs in gener- 

 ally lighter color, grayer belly and shorter tail. The skull is shorter, 

 narrower across the braincase, wider interorbitally, and the upper 

 toothrow is shorter. 



Remarks: This is an example among the white toothed shrews 

 of the Nile apparently acting as a barrier to their distribution. Cer- 

 tainly the specimen of planiceps from Rhino Camp is a bicolor and 

 differs from the new subspecies from Torit in the manner set forth 

 under comparisons. 



Crocidura butleri Thomas 



Crocidura butleri Thomas, Ann. Mag. Nat. Hist., ser. 8, vol. 8, p. 375, September 

 191L (Between Chak Chak and Deim Zubeir, Bahr-el-Ghazal.) 



Specimen Examined: The type. 



Measurements: The measurements of the type, as given by 

 Thomas (1911, p. 375), are as follows: Length of head and body 78; 

 length of tail 34; length of hind foot 13; condyloincisive length of 

 skull 24.0; least interorbital width 4.5; length of upper toothrow 10.5. 



Remarks: The type and only specimen available is unique in that 

 the tail is so much shorter and heavier in comparison to other members 

 of the genus. The extremely pale color of this species is approached 

 by shrews of the Sudan, only by Crocidura pasha to which it is in no 

 way related.

 July 1913. (Kaka, White Nile.) 



Specimens Examined: Two, both in BM, from: Kaka, White Nile, 

 1; Malakal, Upper Nile Province, 1. 



Measurements: An adult female from Malakal, Upper Nile Prov- 

 ince, has the following measm*ements: Length of head and body 110; 

 length of tail 75; length of hind foot 20; length of ear 11; condyloin- 

 cisive length of skull 30.7; greatest breadth of skull 12.7; least inter- 

 orbital width 6.0; length of palate 13.9; greatest maxillary breadth 

 9.3; length of upper toothrow 14.0.
