Specimens Examined: Ten, all in BM, from: El Obeid, 1 ; Sennaar, 

 1 ; Plain of Tokar, 2; 35 miles west of Omdurman, 1 ; Jebel Marra, 3; 

 Niurmya, Jebel Mann, 1 ; Habissa Wells, 1. 



Measurements: An adult male and an adult female from the 

 Jebel Marra measure, respectively, as follows: Length of head and 

 body 577, 661; length of tail 261, 254; length of hind foot 161. 140; 

 length of ear 97, 99; greatest length of skull 160, 149.5; condyloin- 

 cisive length 151, 140.8; length of auditor}^ bullae 21.0, 20.0; gi*eatest 

 width across zygomatic arches 86.7, 74.4; least postorbital width 27.1, 

 28.7; least interorbital width 24.7, 23.1; length of nasals 53.9, 51.4. 



Remarks: These jackals are quite uniform in coloration but vary 

 considerably in their cranial details. G. M. Allen (1939, p. 195) 

 notes that Schwarz (1926) considers soudanicus to be the same as 

 nubianus, which is a new name for variegatus. However, if all these 

 jackals are the same, then the oldest available name is Canis aureus 

 soudanicus.

 Thos mesomelas mcmiUani Heller, Smithsonian Misc. Coll., vol. 63, No. 7, p. 3, 



June 24, 1914. (Mtoto Andei, Kenya Colony.) 



Specimen Examined: One, from Ikoto. 



Measurements: An adult male from Ikoto measures: Length of 

 head and body 680; length of tail 322; length of hind foot 157; length 

 of ear 109 ; greatest length of skull 146.8 ; length of palate 69.0 ; breadth

 interorbital width 29.9; postorbital constriction 35.2; length of nasals 

 49.7; breadth of braincase 53.2. 



Remarks: In attempting to identify the only specimen of this 

 jackal in the collection, it was necessary to compare it with specimens 

 of C. m. elgonae and C. m. mcmiUani. In no way does this specimen 

 disagree with either named kind. Heller erected these two subspecies 

 on the basis of the basal hair color of the belly. In elgonae the basal
