2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6l 



Measurements. — Tanned skin: head and body, 625 mm.; tail, 50; 

 hindfoot, 145; ear, 50. Skull : condylo-basal length, 109; zygomatic 

 breadth, 51 ; upper tooth row, 38 ; PM 1 to muzzle, 31 ; nasals, 43 x 16 ; 

 diameter of orbit, 24; length of premaxillse, 38; orbit to muzzle, 55. 

 Premolars unworn, the milk teeth only recently shed. 



Remarks. — Five specimens of this race belonging to the Field 

 Museum of Chicago have been examined. Four of these specimens 

 were collected in the Kenya Forest by Carl E. Akeley for whom the 

 race has been named. The other specimen is from the Kijabe Forest. 

 Unfortunately no adult male is in the collection, the two males being 

 immature individuals, unsuitable for a type with half-grown horns 

 and with their milk teeth still in use, so that it has been necessary to 

 select an adult female as the type. This pygmy or suni antelope is 

 strictly an inhabitant of forests in the interior highlands. The race 

 here described is confined to the highland forest covering Kenia, the 

 Aberdare Range and the Kikuyu Escarpment.
