Specimens Examined: Sixty-two, from: Torit, 34 (13, MCZ); 

 Obbo, 6; Ikoto, 1; Moli, 30 miles north of Nimule, 3 (MCZ); Juba, 

 1 (BM); Malek, 14 (BAI) ; Mongalla, 2 (BAI); ''Upper Nile," 1 (BM). 



Measurements: Averages and extremes for three adult males and 

 three adult females from Torit, are as follows: Length of head and 

 body 119 (106-130), 113 (99-124); length of tail 153 (150-157), 153 

 (145-160); length of hind foot 32.6 (31-34), 32.6 (31-34); length of 

 ear 18.6 (17-19), 18.6 (18-19); condjdoincisive length of the skull 28.0 

 (27.6-28.4), 28.8 (28.3-29.7); greatest width across zygomatic arches 

 18.4 (17.8-19.2), 18.1 (17.9-18.2); least interorbital width 6.2 (5.9- 

 6.4), 6.1 (5.9-6.3); length of nasals 13.7 (13.3-14.0), 14.1 (13.7-14.7); 

 crown length of upper toothrow 4.9 (4.7-5.0), 4.9 (4.8-5.0); length of 

 auditory bullae 9.3 (9.0-10.0), 9.1 (8.8-9.4); depth of skull at level of 

 auditory bullae 14.1 (13.8-14.5), 13.9 (13.7-14.0). 



Rejiarks: The two specimens from Mongalla are much redder in 

 color than are any of the other specimens assigned to this subspecies. 

 This deepening of color, however, appears to be caused by old worn 

 pelage exposing more of the sub terminal band of color.
