16. Tring Museum, England. A mounted specimen, interesting for the 

 distinctness of the posterior stripes. It was described and figured by P. L. 

 Sclater (Proc. Zool. Soc. London, 1901, vol. 1, p. 166) who believed that it 

 was the same as the animal formerly living in the London Zoological Gardens 

 from 1851 to 1872. That this, however, is not the case was made clear by 

 Ridge way, who publishes a letter from E. Gerrard (who sold the specimen 

 to Lord Rothschild) stating that he had purchased the animal as an old 

 mounted specimen from a Mr. Frank of Amsterdam and had remounted it 

 before selling it to the Tring Museum. Figured by Ridgeway (1909, p. 569, 

 text-fig. 159). 



17. Turin, Zoological Museum. A mounted female, and its skull. The 

 specimen was purchased in 1827 from the English dealers, Leadbeater father 

 and son. It was made the type of Equus trouessarti, figured and described 

 by Camerano (1908, pi.). 



18. Vienna Museum. A mounted female, procured by Ecklon, in 1836. 

 The specimen was described by Lorenz (Proc. Zool. Soc. London, 1902, vol. 1, 

 p. 32) and figured from a photograph which is again reproduced by Ridgeway 

 (1909, p. 568, text-fig. 158). 



19. Wiesbaden Museum, Germany. A mounted specimen, male, which was 

 bought in 1865 from Frank, the Amsterdam dealer. It has no more definite 

 locality than "South Africa." Figured by Ridgeway (1909, p. 572, text-fig. 162). 



From this enumeration it appears that there are in the museums of 

 Europe 17 mounted skins (one a fetus) , a mounted head, 3 skeletons, 

 and 7 skulls ; while elsewhere the only known specimen is a mounted 

 skin of a foal, in the South African Museum.

Although, on account of its somewhat variable pattern, the Bur- 

 chell's Zebra has been divided into many nominal races, only four of 

 these are regarded as valid by Cabrera (1936) in his recent review. 

 Of these four, the typical burchellii is now extinct, and there are few 

 specimens preserved. 



About the size of a small horse, with erect mane and tufted tail, 

 the color pattern consists of alternating dark-brown or black stripes 

 and whitish stripes. Of the former, there are about ten on the neck, 

 a vertical shoulder stripe, four body stripes, then on the flanks three 

 or four that turn back dorsally, somewhat paralleling the median 

 black stripe. The characteristic feature of typical Burchell's Zebra 

 is that the lower haunches and both fore and hind legs lack the small
