MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 453 



As may be noted in the following accounts, there are vast gaps in 

 the distributional patterns of practically every species. It is recog- 

 nized that this report is at best only preliminary and that many of the 

 kinds treated here as species will probably be shown in the future to 

 be related as subspecies. It is hoped, though, that this work will find 

 its way into the hands of interested amatem-s and professional zool- 

 ogists and epidemiologists who will have the opportunity to fill in 

 some of the annoying gaps in the distributional patterns. Much field 

 work remains to be done in the Sudan in order to understand more 

 completely the effects of isolation and the barrier effect of the Nile if 

 such exists.

Figure 2,o 



Type: BM No. 23.1.1.35, adult male, skin and skull, from Umm 

 Keddada, Darfur Province, Anglo-Egyptian Sudan. Obtained March 

 15, 1922, by Lynes and Lowe, original No. 1159. 



Specimens Examined: Four, all in BM, from: Umm Keddada, 2; 

 32 miles east of El Fasher, 1 (skull only) ; El Obeid, Kordofan Prov- 

 ince, 1 (skull only). 



Diagnosis: A small extremely pale hedgehog in which the white 

 subterminal band of the spine is broad and the terminal black band 

 is minute. Entire underparts, brow band, hands, and feet white. 

 Skull small, zygomatic arches not widely flaring, interorbital region 

 relatively narrow, postpalatal ridge well developed, mesopterygoid 

 region relatively narrow, upper molars relatively large. 



Measurements of the Type Specimen: Length of head and body 

 167; length of tail 16; length of hind foot 25; length of ear 26; con- 

 dylobasal length of skull 37.4; length of palate 21.4; width of rostrum 

 at level of antorbital foramen 9.6; length of nasals 14.1 ; least postor- 

 bital width 9.9; width across zygomatic arches 23.6. 



Comparisons: From Atelerix pruneri pruneri as known by a speci- 

 men from Singa, Blue Nile, A. p. lowei differs in markedly lighter 

 color and a smaller skull in all measurements taken. 



From A. p. oweni, A. p. lowei may be distinguished by its markedly 

 lighter color and smaller skull in all measurements taken. 



Remarks: This small hedgehog bears out the pale coloration of 

 most of the other mammals obtained by Ljmes and Lowe at lower 

 elevations in Darfur and Kordofan. The extreme amount of white on 

 the spines and the narrowness of the black bands create a strikingly 

 light colored animal. 



The type specimen was trapped in a hedgerow of "gufiie."
