?6 THE SEROUS COLLECTION. 



considerably less dark hair on neck and throat. The Giant or 

 Derby Elands are quite distinct from Taurotragus oryx, having 

 larger horns, and much broader ears, with black band ou inner side 

 of hind margins. General colour richer, forehead in females 

 chestnut-red; in old bulls a tuft-like growth of darker hair de- 

 velops. White suborbital markings distinct, in the form of two 

 narrow white streaks, separated by a dark brown nose-stripe. 

 White spots on sides of face and white bar across lower throat, 

 which is fringed with a narrow mane of dark brown hairs. 



The only specimen of this Eland in the Collection is a female, 

 the horns of which measure as follows : length from point to base 

 28i ; circumference 8f ; spread from tip to tip 13. In subadult 

 specimens the horns are usually longer, as in old age the horns get 

 worn down very considerably. The record horn-length from point 

 to base is 41 inches. 



Typical locality west of the White Nile, Bahr-el-Ghazal Pro- 

 vince, in about 7N. lat. ; the race appears to be confined to the 

 Bahr-el-Ghazal and Lado Provinces, Sudan.

RETICULATED GIRAFFE. 



GIRAFFA EETICULATA. 



Giraffa camelopardalis reticulata, de Winton, Ann. Mag. Nat. Hist. ser. 7, 



vol. iv. p. 211, 1899. 

 Giraffa reticulata, Thomas, Proc. Zool. Soc. 1901, vol. ii. p. 476. 



Size rather less than in the other East African Giraffes. Dis- 

 tinguished from camelopardalis by the general colour pattern, the 

 body being reddish brown with a white network superimposed, 

 the dark body-colour thus being cut up into a number of large 

 reddish-brown rectangular patches. On the head the reticulations 

 are considerably smaller and are continued forwards over the 

 cheeks as far as the chin. Anterior horn large and very stout. 



Typical locality, Lorogai Mts., north of Laikipia District ;
