MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 511 



The color in a recently taken specimen from Kamisa is rather light 

 above and graduall}^ shading over the sides into the plumbeous based 

 whitish hairs of the belly. The blackish tips of the hairs is most 

 intense over the shoulders and diminishes in amount over the rump 

 and on the upper legs. The nose and a ring around the eye are of pm'e 

 color near Cinnamon Buff. The skull, which is of an adult male, is 

 quite long with heavy supraorbital ridges and heavy z3^gomata. The 

 rostrum is short and wide and the teeth are relatively massive. The 

 auditory bullae are small but well inflated. 



The specimens from Khartoum are somewhat paler than the animals 

 from farther east.

Specimens Examined: Thirty-four, from: Torit, 17; Ikoto, 1; 

 Nimule, 2; Malek, 8 (BM); 25 miles east of Lake No, 1 (BM); Bahr- 

 el-Ghazal, 1 (BM); Badigeru Swamp, 20 miles east of Mongalla, 1 

 (BM); Fashoda, 1 (BM); Dud Majok, 1 (BM); Wau, 1 (BM). 



Measurements: Averages and extremes of three adult males and 

 three adult females from Torit are, respectivel}^ as follows: Length of 

 head and body 102 (94-110), 101 (98-104); length of tail 112 (104-120), 

 110 (107-116); length of hind foot 24.5 (24-25), 25 (25); length of ear 

 14 (14), 15 (14.5-15.5); greatest length of skull 28.0 (27.1-28.5), 

 27.7 (27.0-28.3); condyloincisive length 24.9 (23.9-25.6), 24.6 (24.0- 

 25.4); length of auditory bullae 5.4 (5.0-5.6), 5.4 (5.2-5.6) ; crown 

 length of upper too throw 4.9 (4.9-5.0), 4.8 (4.8-4.9); least inter- 

 orbital width 4.5 (4.5), 4.5 (4.4-4.6); width of rostrum at level of 

 antorbital foramen 3.6 (3.5-3.8), 3.5 (3.4-3.7); length of nasals 10.2 

 (9.8-10.6), 10.2 (9.8-10.5); greatest width across zygomatic arches 

 12.9 (12.6-13.2), 13.1 (12.5-13.5). 



Kemarks: There is an apparent sexual difference in size of body, 

 length of tail, length of hind foot, and some cranial characters in which 

 the females generally average slightly larger than the males. In gen- 

 eral, the color is quite uniform. Three of the specimens from Torit 

 are only slightly paler than is the rest of the series, and the single 

 specimen from Wau is of the same color as the majority of the speci- 

 mens from Torit. 



This subspecies of striped mouse seems to have the largest geographic 

 range of any of the rodents found in the Sudan. The explanation for
