 Ichneumia abu-wudan Fitzinger and Heuglin, Sitzb. K. Akad. Wiss. Wien, Math.- 



Nat., vol. 54, sec. 1, p. 561, 1866. (Berbera, Somaliland.) 



Specimens Examined: Thirty, from: Roseires, 3 (BM); Soba, 2 

 (BM); Shereik, 2 (BM); Merowe, 2 (BM); Kerma, 1 (BM); Shendy, 

 5 (BM) ; Nagichot, 1 (BM) ; Bor, 2 (BM) ; Moru District, 1 (BAl) ; 

 Ayod, 1 (BM); Singa, 1 (BM); Chak Cliak, 3 (BM); Juba, 1 (BM); 

 Malek, 1 (BM); Torit, 3 (1 MCZ); Ikoto, 1. 



Measurements: External measurements of an adult male and an 

 adult female from Shereik, are, respectively, as follows: Length of 

 head and body 4G7, 470; length of tail 354, 430; length of hind foot 98, 

 103; length of ear 31, 36. Cranial measurements of an adult male 

 from Shereik and an adult female from Soba, are respectively^: Greatest 

 length of skull 91.6, 97.2; condyloincisive length 89.6, 94.5; greatest 

 width across zygomatic arches 46.0, 50.8; least postorbital width ?, 

 18.5; least interorbital width ?, 19.6; breadth of braincase 32.5, 31.6; 

 length of auditor}^ bullae 18.3, 18.4. 



Remarks: The white-tailed mongooses have a melanistic phase 

 which makes the common name seem rather absurd. These melanistic 

 specimens have lost the white tail tip, either completely or in part. 

 There seems always to be present some white, which occurs only at 

 the base of the hairs, while the tips of the same hairs in the melanistic 

 phase are black. 



Melanism does not seem to be an age character since white and 

 black tails occur at the same age levels.
