time the A. iiemippus did in Mesopotamia). The most Horse- 

 like in structure of any. The Hippotigris isabellinus of Col. C. H. 

 Smith is probably founded on a Quagga-foal, perhaps not very exactly 

 represented. Such an animal as this, or as the ■ Isabelline Zebra' 

 of Levaillant, could not have been overlooked by all subsequent 

 explorers of S. Africa.

 even to Abyssinia and to Congo, and southward to the Gariep

 habiting the deserts of Syria, Mesopotamia, and the northern parts 

 of Arabia. 



6. A. onagee : E. asinus onager, Pallas. The Koulan or Ghor- 

 khur inhabits W. Asia, from 48° N. latitude southward to Persia, 

 Beluchistau, and W. India.
