MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 513 



length 25.5, ?; length of upper toothrow 4.9, 4.9; least interorbital 

 width 4.3, 4.3; breadth of rostrum at level of antorbital foramen 3.3, 

 3.3; length of nasals 10.4, 9.1. 



Remarks: L. d. nubalis is somewhat smaller than the nominate race 

 and is pronouncedly brighter in color. The color of dunni is a pale buff 

 while nubalis is a bright golden color. The sides and flanks, instead of 

 being wliite as in dunni, are washed with the golden ochraceous color 

 of the dorsum. 



Lemniscomys lynesi Thomas and Hinton 



Lemniscomys lynesi Thomas and Hinton, Proc. Zool. Soc. London, p. 267, July 6, 

 1923. (Central Jebel Marra, Darfur.) 



Specimens Examined: Ten, all in BM, from: Jebel Marra, 3; Cen- 

 tral Jebel Marra, 6; South Downs, Jebel Marra, 1. 



Measurements: An adult female from South Downs, Jebel Marra, 

 measures as follows: Length of head and body 101; length of tail 104; 

 length of hind foot 23 ; length of ear 14 ; condyloincisive length of skull 

 23.9; crown length of upper toothrow 5.1 ; least interorbital width 4.5; 

 breadth of rostrum at level of antorbital foramen 3.6. 



Remarks: In the original description of this species, Thomas and 

 Hinton suggested that it was more nearly related to L. zebra {=L. 

 barbarus zebra) than to any other gi'oup in the genus. In all cranial 

 details, and, most strikingly, in the distribution of the dorsal lines and 

 spots and in degree of spininess, L. lynesi is most closely allied to L. 

 striatus. From aU characters stuaied it appeai-s as though this is not 

 a valid species but merely a subspecies of striatus. I feel certain that 

 intergradation could be demonstrated if specimens were obtained from 

 intermediate localities. However, until such time as specimens show- 

 ing intergradation are obtained I prefer to let the name stand as a fuU 

 species. 



The skull, as well as the skin, is markedly different from dunni. 

 The color is the darkest of any of the kinds in the Sudan. The skull 

 differs from that of dunni in the markedly different shape of the bullae, 

 in the length of the anterior palatine foramina, and in the very different 

 structm'e of the pterygoid region. 



Lemniscomys macculus macculus (Thomas and Wroughton) 



Arvicanihis macculus Thomas and Wroughton, Trans. Zool. Soc. London, vol. 19> 

 p. 515, March 1910. (Mokia, southeastern Ruwenzori, Uganda.) 



Specimens Examined: Three, from: Torit, 1 ; Nimule, 2. 



Measurements: The measurements of an adult male from Nimule, 

 are as follows: Length of head and body 96; length of tail 121 ; length 

 of hind foot 25; length of ear 16; greatest length of skull 26.2; condy-
