Mount Kenia and the Man Escarpment northward through the 

 Lake Rudolf basin, southern Abyssinia, and Somahland. "^ Mat- 

 schie's type-locahty is therefore near the extreme southwestern 

 limits of distribution, and it seems more than probable that Heller is 

 correct in placing Lonnberg's rendilis in synonymy. No striped 

 hyenas are known from the Guas Ngishu country, westward from 

 the type locality of hergeri.

Specimens. — Two, from the following locahties: 



Eritrea: "Habesch,'' 1 (Schrader). 



British Somali: Berbera, 1 (Swayne). 



Through the kindness of the authorities at the Museum of Com- 

 parative Zoology I have been able to borrow for study in this con- 

 nection the skin and skull of an adult male striped hyena coUectedby 

 Dr. John C. Phillips and Dr. Glov<'r M. ^Vlleii at Magaugani, Blue 

 Nile, Sudan. This specimen was j-ecorded by iUlen as Hysena 

 hienomelas Matschie, and can be considered as typical of that race, 

 and the much earlier named duhia of Schinz. The specimen agrees 

 in all details with our material from Eritrea and British Somali. 

 The form represented differs markedly from //. li. hergirl of northern 

 British East Mrica. It is decidedly lighter in color throughout, the 

 brown, dark buff, and pinkisli tones of hergeri are replaced with very 

 pale bufF or whitish, and the brown tips to tlie long hairs of the tail 

 in hergeri are replaced v.'ith blackish. The animal thus presents a 

 much lighter and more grayish, less buify and brown, appearance 

 throughout, with a lighter, more wliitish tail. 'Y\\e body and limb 

 stripes, as a consequence* of the hghter ground color, appear much 

 more sharply marked than in hergeri. The skulls of duhia are very 

 much as in hergeri, but the second upper premolor is placed almost 

 straight in the slightly curving tooth row, not sharph" turned diago- 

 nally inward anteriorly as in hergeri. This character is diagnostic and 

 easily seen in our eleven skulls of hergeri and the two skulls of duhia, 

 and thus appears to be a constant difference between the two forms. 

 A line drawn along the inner margin of this tooth in hergeri, and con- 

 tinued forward to the incisors, crosses the outer incisor on the opposite 

 side of the skull, or at least the next tooth inward. The same line
