REMARKS ON THK TKETII OF REPTILES. 87 



Here, then, we have notices, more or less distinct, of per- 

 haps five species additional to the six which are well known 

 (if, indeed, the wild ass can be considered as well known). — 

 First, in the African continent, besides the three striped spe- 

 cies of the Cape, the striped wild ass of Bruce, as distinguish- 

 ed from his zebra ; and, in Asia, the wild ass of Bell, with 

 " hair waved, white and brown, like that of a tiger.'''' Then, 

 there is the " Isabelline Zebra " of Le Vaillant, of a uniform 

 sort of cream colour, with a yellowish tinge ; the Khur of 

 Persia and Arabia, also stripeless, but otherwise very like the 

 Djigguitai, and which of course is the " wild mule" of the 

 ancients ; and finally, the Kiang of Thibet, also, it would 

 seem, much resembling the Equus hemionus, with an ob- 

 scure i}) stripe in the adult, more distinct in the foal, running 

 along each side of the back to the tail, and which is moreo- 

 ver like the true zebra, a mountain animal, that " bounds up 

 the rocks," so as to defy pursuit. The re-publication of these 

 notices may possibly lead to the desired investigation. 



In conclusion, I would suggest that it would be quite as 

 well if geologists, who continually have occasion to speak of 

 fossil remains of this genus, were always to mention them 

 under the latin name of Equus, instead of the English Horsey 

 inasmuch as it is very generally supposed, in consequence of 

 the latter term being employed, that the Eq. cahallus is the 

 animal so commonly met with in the European superficial 

 strata, which there is no reason to suppose is veritably the 

 case. '

Art. VI. — Remarks on the teeth of Reptiles, from the Tilgate Grit 

 of Battle and St. Leonard's. By John Edward Lee, Esq. 



The following remarks on the teeth of reptiles from the Til- 

 gate grit and clay of Battle and St. Leonard's, may perhaps 

 not be unacceptable ^o you for insertion in the Magazine. 



The fall in the cliff near the church at St. Leonard's, which 

 took place last winter, afforded an opportunrty of examining 

 more particularly the stratum which contains the patches of 



* We cannot help strongly seconding this judicious recommendation of 

 Mr. Blyth's. The impropriety has most probahly originated in the circum- 

 stance of the close agreement displayed in the characters of the teeth 

 throughout the species of the genus Eqnus. — Ed.
