GORGON ALBOJUBATUS MEARNSI, new subspecies 

 Loita White- Bearded Wildebeest 



Type from the Loita Plains, British East Africa; adult male, Cat. 

 No. [63020, U. S. Nat. Mus. ; shot by Dr. E. A. Mearns, June 28, 

 1 1 1: hi ; original number 6809. 



Characters. — Differs from the typical Gorgon albojubatus of the 

 Athi Plains by dark colored limbs, smaller body size, the skull being 

 decidedly less in length ; and less widespread horns which are curved 

 downward well below lower margin of orbit and about level with the 

 foramen magnum. In albojubatus the horns extend much more hori- 

 zontally, their lower edge not extending below the lower edge of the 

 orbit. 



Coloration of type: dorsal color drab-gray spotted and banded by 

 dark patches due to the tips of the hair becoming dark brown as

 gray. This faded condition of the hair is not seasonal but is a chronic 

 condition in the wildebeest. Limbs darker than the body, uniform 

 olive-brown deepening somewhat on the pasterns. Chest, fore part of 

 belly and lower sides much darker than the back, clove-brown, the 

 chest medially black. Groins, axillae and inside of legs drab-gray like 

 the back. Tail like the back in color and furnished along the lower 

 surface and at the tip with a long black tuft of hair fully as long as the 

 tail its. If. Neck like the back in ground color but -bowing ragged 

 cross bands of dark hair bases ; a mane of long black hair extend- the 

 whole length of the nape and is continued as a black line on the hack as
