smaller size and brighter color. Of the subspecies of Lepus capensis 

 found in the Sudan, havjkeri is the most nearly related yet the most 

 distantly removed geographically.

 (Kaka, White Nile.) 



Specimens Examined: Twenty-one, all in BM, from: Kaka, White 

 Nile, 1 ; Zalingei, 5; Kulme, Wadi Aribo, 3; 75 miles east of El Fasher, 

 1 ; 50 miles east of El Obeid, 1 ; Gerazi, 1 ; Dorila Lakes, Jebel Marra, 

 1; 70 miles west of Nahud, 1; Juga Juga, 15 miles east-northeast of 

 El Fasher, 1 ; Malhab, 1 ; Agageh Wells, 2; Jebel Ahmed Aga, 3. 



Measurements: An adult male from Zalingei and an adult female 

 from Kulme, Wadi Aribo, measure respectively as follows: Length of 

 head and body 470, 490; length of tail 85, 100; length of hind foot 

 104, 112; length of ear 103, 112; greatest length of skull 85.9, 90.8; 

 median length of nasals 35.6, 38.7; least interorbital width 17.1, 

 19.1; greatest width across zygomatic arches 38.2, ?; condyloincisive 

 length 76.3, 79.9; alveolar length of upper molar series 16.2, 16.5; 

 breadth of braincase 33.8, 34.9. 



Remarks: This is the darkest subspecies of hare to be found in 

 the Sudan. This darkness is the result of the broad black tips of 

 the hairs of the dorsum. The skull is peculiar in that in dorsal out- 

 hne it is "domed" and not flattened as in L. c. isabellinus and L. c. 

 aegyptius. In all other aspects hawkeri is quite typical of what is 

 now considered to be the species capensis.

 6; Shendy, 8.
