MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 549 



9.3; least postorbital width 9.1 ; length of nasals 14.3; width of rostrum 

 at level of antorbital foramen 8.3. 



Comparisons: From C. o. ochraceocinereus as known from 400 miles 

 west of Juba, C. o. oweni differs in darker color throughout; the skull 

 has the rostrum narrower, the pterygoid fossae smaller, auditory 

 bullae smaller but more inflated ventrally, hard palate markedly 

 narrower, upper toothrow shorter, width across postorbital processes 

 greater, interorbital width less, skull flatter, and the orbital notch 

 raarkedl}^ reduced. 



Remarks: These specimens from Equatoria Province need no 

 comparison with other named kinds, which are all far removed geo- 

 graphically from this area. 



The status of the name ochraceocinereus is somewhat in doubt, but 

 until such time as a revisionary study has been made I prefer to refer 

 this new subspecies to that species. 



The label on the specimen from Nagichot bears the collectors 

 remark, "Plentiful in mountain-meadows." Unfortunately only the 

 single specimen was obtained and saved.

Canis adustus bweha (Heller) 



Thos adusta bweha Heller, Smithsonian Misc. Coll., vol. 63, No. 7, p. 2, June 24, 

 1914. (Kisumu, British East Africa.) 



Specimens Examined: Three, all in BM, from: Chak Chak, 1; 

 Bahr-el-Ghazal, 1 ; Bor, 1. 



Measurements: An adult male from Chak Chak has the foUowing 

 measurements: Length of head and body 673; length of tail 279; 

 length of hind foot 182; length of ear 70; gi'eatest length of skull 161.0; 

 condjdoincisive length 144.2; length of auditory buUae 21.4; greatest 

 width across zygomatic arches 78.8; least postorbital width 27.9; 

 least interorbital width 28.4; length of nasals 60.0. 



Remarks: Canis adustus may be distinguished from Canis aureus, 

 with which it apparently occurs, by smaller size, markedly smaller 

 cheekteeth, smaller but more inflated auditory bullae, and the choanae 

 tapering sharply posteriorly. The skin is lighter in color and the -hair 

 is shorter; the ears are smaller and decidedly blackish in color as 

 opposed to pale and long in aureus.
