2-42 Mr. Gray's Revision of the Equidce, 



which, from his description, if it exists, Is most probably a species 

 of Lama (Auchenia.) 



Edwards, iu his Gleanings of Natural History, figured what he 

 considered as the male and female Zebra, the former of which I 

 consider to be the true Zebra, and the latter is perhaps the 

 Quagga ; but both the figures have the bands too pale, and indis- 

 tinct , and the latter especially has some spots on the rump, which 

 do not exist in the Quagga, and yet it has not the bands of the 

 Asinus BurchelUi. 



Linneus, in his Systema Naturae, described three species, the 

 Horse, Ass, and Zebra, the latter of which he characterized, E. 

 fasciis fuscis versicolor. Referring to the two figures of Edwards, 

 and adding as a description Color albidus sen rufescens, fasciis 

 nigris digitos tres latis per totum corpus transversis, #c, I am 

 not able to reconcile these two descriptions, but neither the Zebra 

 nor the new species has the bands purely black, but very deep 

 blackish brown : and Linneus certainly agreed with Edwards, in 

 considering the two, that the latter author figured as sexes. 



Pallas, in the nineteenth volume of the New Commentaries of the 

 Russian Academy, adds another species, by the name of theEquus 

 Hemionus, which is called Dshikketei by the Tartars, and which 

 Cuvier considers to be the Wild Mule of the ancients. 



Capt. Gordon sent aspecies of this family, called Quagga, from 

 the Cape to Amsterdam, where it was first described and figured 

 from his drawing in the Dutch edition of Buffon, and afterwards in 

 the Supplement to the French editions, whence it has been de- 

 scribed by most Zoologists. 



Burchell, in his Travels, has taken notice of a new species, 

 which he has for some reason called E. Zebra, and which he says 

 is confined to the flat parts of Africa, and the old Zebra under the 

 name of E. Montanus, as this species is found only in mountainous 

 parts. 



Le Vaillant, in his curious Travels, has mentioned another 

 species under the name of L'ane Isabelle, (vol. iii. page — ) 

 which he says is of a plain Isabella colour, without any band ; but 

 nobody since his time, as far as I can learn, has mentioned it: 

 may it not be au albino variety of the Zebra, or Quagga ? as the
