MAMMALIA. 243 



dence whicli I can add is in favour of the distinction. 

 I brought away with me three skulls of large males. 

 One is that of a veiy old animal with enormous tusks, 

 the upper pair being no less than eleven inches long 

 each outside the jaw, measured along and outside of 

 the curve. In all three skulls both upper and lower 

 incisors are permanent. In old specimens of P. cethio- 

 picus both are generally wanting.^

Rhinoceroses appear to be confined to the lower 

 elevations in Abyssinia ; they do not ascend above 

 about 5,000 feet elevation in the northern portion of 

 the country, and they are entirely wanting on the high 

 plateau. I only met with them on the banks of the 

 Anseba, where they were tolerably common. AU be- 

 longed to the black type^ — ^the white African rhinoceros 

 does not appear to have been met with north of the 

 equator. 



Although the rhinoceros of Abyssinia and Nubia was 

 described long ago by Bruce,^ very few specimens have 

 ever reached Europe. The difficulty of carrying the 

 spoils of so large an apimal is very great. Mr. Jesse 

 brought away the complete skeleton of an adult female,

 * Bruce's figure, however, represents an Indian (one-horned) Ehinoceros, 

 with an additional horn.
