MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 467 



Diagnosis: General over-all color of upperparts Hair Brown 

 shading to Mouse Gray on the belly; flank glands same as dorsal 

 color; hands, feet, and tail brownish. Skull relatively long, rostrum 

 relatively long, upper toothrow long and relatively as well as actually 

 wide. 



Measurements of the Type Specimen: Total length 146; length 

 of tail 52 ; length of hind foot 1 5 ; length of ear 5 ; condyloincisive length 

 of skull 23.5; greatest breadth of braincase 10.2; greatest maxillarj'' 

 breadth 7.2; length of palate 9.5; length of upper toothrow 10.2; 

 least interorbital width 4.4. 



Comparisons : The only subspecies with which C. t. tephra needs to 

 be compared is C. t. nilotica, from which it differs in: Color lighter in 

 all respects, size about the same in all respects, skull somewhat longer, 

 braincase wider, width across maxillaries greater, rostrum longer and 

 upper toothrow somewhat longer. 



Remarks: This new subspecies is remarkably lighter in color than 

 is C. t. nilotica. In none of the specimens examined does the color 

 begin to approach the saturate condition found in the latter. The 

 type series is remarkably constant in color but the size of the skulls 

 varies rather widely. The greatest difference in these skulls is in one old 

 male in which the teeth are v*^orn almost flat. This skull is about 1.5 

 mm. longer in the condyloincisive length than is that of the type. 

 Most of this extra length is in the posterior development of the brain- 

 case, which is more than one millimeter longer than in the type.
