103; lower tooth-series, 106-5; upper car nassial, 36x20; lower 

 carnassial, 28 X 11. 



Hah. Odixeina, Boran Country. 



Tyjie. Old female. B.M. no. 9.6.1.14. Collected by Mr. Drake- 

 Brockman. 



Remarks. — The type-skin lacks the head and fore part of the 

 neck, but it is so different from all the other Spotted Hyaenas 

 that, although the only specimen and an incomplete one, it 

 deserves to be considered a new form. C. kibonotensis, pale 

 reddish in colour like ?^nfopicta, has the spots dark brown, not red, 

 and its skull, an excellent photograph of which has been published 

 by Lonnberg, is also different from that of the present species or 

 race. 



Crocuta thomasi, sp. n. 



Diagnosis. — A pale grey, black-spotted Hysena, with the skull 

 of the narrow type. 



Colour. — General colour pale gi'ey, strongly suffused with buff" 

 on the fore quarters, and marked with large black spots, very 

 irregular in form, some of them being elongate and even some- 

 what linear. Mane dirty ochre-yellow, fading to cream-buff" on 

 the sides of the neck, where there are two irregula.r rows of faint 

 burnt-umber spots. Feet and legs to near the elbow and the 

 knee dark clove-brown, almost black. Tail pale grey, blotched 

 with small blackish spots, and with the distal half black. 



Skull. — Palate narrow, but not so much as in C. ru/ojncta, its 

 largest breadth being practically equal to the length of the upper 

 tooth-row, and even considerably exceeding it in young specimens, 

 in which the carnassial is not yet quite developed. Hinder out- 

 line of paroccipital processes forming a vertical line. 



Skull-measureinents (of type). — Condylo-basal length, 245 mm. ; 

 zygomatic breadth, 165 ; interorbital breadth, 54 ; postorbital con- 

 striction, 41 ; rostral breadth on canines, 58 ; width of palate 

 across the carnassials, 101 ; mandible, from condyle, 175; upper 

 tooth-series. 100; lower tooth-series, 107; upper carnassial. 

 35 X 18 ; lower carnassial, 26 x 10" 5, 

 Hah. Ankole, Uganda. 



Type. Adult male, B.M. no. 1.8.9.27. Collected by Sir Harry 

 Johnston. 



Remarks. — I have seen two other specimens, from Ankole also, 

 one obtained by Sir Harry Johnston (B.M. no. 1.8.9.28) and the 

 other, a young female, collected by Mr. Delme Radcliff"e (B.M. 

 no. 5.4.3.4). All three are rea.dily distinguishable from the 

 other grey Hyaenas of East Africa. The Abyssinian C. leo7itiewi 

 is not pale grey in colour, but " braunlichgrau, auf der Mitte des 

 Rlickens rostbraunlich," and has a smaller skull (zygomatic 

 breadth about 155 mm., against about 165 in C. thomasi). In 

 C. panganensis, from the Coast Region, the colour is da.rker, 

 brownish ash, verging to rusty brown in the mane, a,nd the skull 

 is considerably broader behind the postorbital processes. The
