On new Uaces of African Ungulates. 31 



incrassate, fore-tibia stout, and tarsus armed with a sharp 

 broad tooth, and also with a hidden curved tooth near apex. 



Abdomen only slightly broader than the pterothorax, prac- 

 tically subpavallel to seventh segment, and thence gently 

 rounded to base of tube ; well-developed wing-retaining 

 bristles on segments 2-6. Tube about 0*6 the length of 

 head, 1"6 times as long as broad near base, and about 0*4 as 

 bro:\d at apex as at base, evenly narrowed from base to tip. 

 Terminal hairs about as long as the tube, slender. Lateral 

 abdominal bristles long and slender on segments 1 to 9, 

 mostly as long as or longer than tube. 



A very distinct species of the group characterized by the 

 short n)outh-cone, and readily recognized by the form of the 

 head, the relative lengths of the antennal joints, and the 

 distinctive tyjje of coloration. I have pleasure in naming 

 the species in honour of its discoverer.

V. — Diagnoses of neiv Races of African Ungulates. 

 By Ernst Schwarz. 



This is the third paper dealing with the Ungulates brought 

 home by the Duke of Mecklenburg's second Central-African 

 expedition. In working out the forms now descril)cd, the 

 material in the British Museum has been studied, and has 

 been of the utmost value. Tie thanks of the writer for the 

 facilities afibrded are due to Mr, Oldtield Tiiomas, the Curator 

 of Mammals.

A rather short and broad-faced race, with the orbits 

 strongly projecting and decidedly laid forward. 



Orbits strongly projecting ; when seen from in front their 

 lateral margin is seen to be placed almost vertically, their 

 upper margin to be much higher than the lanibdoi'd crest.
