UNRECORDED SPECIMENS OF THE QUAGGA. 



565 



Museum (text-fig. 163), Amsterdam (text-fig. 170), Edinburgh 

 (text-fig. 165), and Tring (text-fig. 159) specimens ; the last being 

 (he thought) that really photographed by York. (2) He applies 

 the name E. quagga lorenzi to the famous Vienna specimen (text- 

 fig. 158). Bat Mr. Lydekker is now very doubtful whether the 

 division into races is justifiable, although it is possible that the 

 Vienna specimen may be distinct, and " despite certain differences 

 in regard to the width and backward extension of the stripes, and 

 also the relative proportions of the white and fawn areas," he is 



Text-fiff. 157. 



The Basel Quagga (femalo) ; Silo, Cape Colony, 1864. 



'■'■ disposed to regard the quaggas figured by Edwards, Harris, and 

 Hamilton Smith, as representing the same type of animal." 



Mr. Pocock has added a third subspecies : E. quagga danielli 

 (text-fig. 179, p. 585). 



Mr. Pocock has argued that the Burchell Zebras and the 

 Quaggas of Cape Colony are only su,bspecifically distinct, and he 

 includes all the varieties of the Burchell Zebra as well as the true 

 Quaggas of Cape Colony under the species E. quagga. 



Whether these two types of animals were specifically or sub- 

 specifically distinct, the relationship between them was extremely 

 close. Furthermoi-e, it is genei-ally admitted that the Vienna 

 Quagga, of all the specimens hitherto published, comes nearest to 

 the true Burchell Zebra.
