1904.] SUBSPECIES OF GIRAFFA CAMELOPARDALIS. 219 



Decisive evidence of the unity of the two forms is, however, 

 afforded by the skin of the fore-legs and withers of a male from 

 Kilimanjaro presented, at my suggestion, to the British Museum by 

 Mr. Rowland Ward. In this skin, which has jagged and somewhat 

 star-like chestnut spots of the character of those of the so-called 

 schillingsi, the lower part of the fore-legs is fawn-coloured, and 

 spotted ahnost or quite down to the hoofs, after the fashion of the 

 type of tijjpelskirchi. In other words, we have a tippelskirchi from 

 the typical schillingsi locality, which is, I think, sufficient to show 

 that the two are identical. 



Hitherto we have had no evidence as to whether the male of 

 the present race has a third hoiii. That such an appendage was 

 present is, I think, demonstrated by sketches of a Giraffe's head 

 and skull, together with certain notes, made some years ago by 

 Mr. Vaughan Kirby in Portuguese East Africa, for the oppor- 

 tunity^ of seeing which I am indebted to Mr. Ward. 



These sketches show the head and neck of a male giraffe, having 

 the type of coloration characteristic of the present form, and 

 carrying a well-marked third horn on the forehead. At the 

 same time this third horn appears to be decidedly smaller than in 

 G. c. rothschildi ; and I gather from Mr. Kirby's notes that some 

 of the bull giraffes from the same locality have little or no third 

 horn. This accordingly demonstrates that in Portuguese East 

 Africa a Giraffe, closely allied to and probably identical with 

 G. G. tippelshirchi^ is tending towards the Cape type in the cha- 

 racters of the skull, as is the typical tippelshirclii in the coloration 

 of the limbs. 



I may add that Mr. Yaughan Kirby regarded his Giraffe as 

 indicating an undescribed form. 



That G. c. rothschildi grades into tijjpelskircki, and the latter 

 into the under-mentioned ISTorth- Transvaal form, is, I think, 

 quite possible. It is somewhat curious that immediately south 

 of the equator the Giraffes on the eastern side of Africa tend to 

 become spotted and dark-coloured on the lower part of the limbs, 

 and at the same time to lose the third horn of the bulls. 



6. Congo Giraffe.

Girafa camelopardalis congoensis Lydekker, Hutchinson's 

 Animal Life, vol. ii. p. 83 (1903). 



Hah. Katanga, Congo Free State. 



A race typified by an adult mounted bull in the Congo Museum 

 at Tervueren, near Brussels (text-fig. 33, p. 220). 



Specially chai'acterised by the Avell- developed frontal horn, 

 coupled with the full spotting of the lower portion of the limbs 

 (especially the hind pair), of which the ground-colour is grey- 

 fawn, and the large size and subquadi-angular form of the 

 body-spots, which show no tendency to split up into stars.
