 p. 4. June 24. (Loita Plains, British East Africa; type in U. S.Nat. 

 Mus.) 



Specimeiis. — Six, asi'oUows: 



British East Africa: Loita Flaius, Sotik, 2 (ilaincy, HelJor); 

 Nairobi, 2 odd skulls (Mearns); Telek River, Sotik, 1 (Heller). 



German East Africa: Ikoma, 1 skull (E. Clark). 



The material representing this race of the side-striped jackal is 

 rather uusatisfactorj'. The subspecies is not a vory well-marked one. 

 and I will not be surprised if, when larger serie.-i for exi^tnination are 

 available, it is found impossible to recognize more than one race of 

 adustus in British East Africa. Two of the three skins are very con- 

 spicuous in their white inarKings below; but the third, a youngish 

 female, is indistinguishable from specimens of Thos adnsUis bwcM. 

 This color difference is not sexual, as suggested by Heller,^ because 

 the second Loita Plains specimen, in all respects colored like the 

 type male, proves to be a female, and not an adult male, as stated 

 by Heller.

Specimens. — Eleven, from localities as foUows: 



British East Africa: Kasorongai Kiver, 2 (Mearns, Ijoring); 

 Laikipia Plains, 2 (K. Koosevelt, Heller); Lake Naivasha, I (Heller); 

 Loita Plains, Sotik, 2 (Rainey, Heller); Naivasha Station, 1 odd 

 skull (Loring); Oni, 1 (Loring) ; Sotik Road, Sotik, 1 (Rainey) ; Suswa 

 Plain, 1 (Rainey). 



This subspecies is readily distinguishable from the more northern 

 variegatus by its much smaller size. It is the most southeni race of 

 aureus and the only one known to extend south of the Equator.
