Dr. J. E. Gray on the Guemid. 215 



I thought that it was probably the summer state of the 

 same animal, and perhaps a smaller variety of it. I first gave 

 a notice of these skins in ' Scientific Opinion' for October 6, 

 1869 ; and as the horns of the male showed that it was different 

 from any known deer, I proposed the name Anomalocera for it ; 

 but (recollecting that this name had several times been used) 

 in the longer account of the deer which I gave in the ' Proc. Zool. 

 Soc' 1869, pp. 496-499, with figures of the horns of the male 

 and skull of female, I altered the name to Xenelapluis leucotis. 

 But as it is now found that the original Capreolus leucotis from 

 the Straits of Magellan is a different species with very different 

 horns, and was a larger-sized animal, I have called this, in the 

 'Ann. & Mag. Nat. Hist.' Dec. 1872, p. 445, Xenelajyhus 

 anomalocera. 



The animal to which the skins of the male and female now 

 received from Don Enrique Simpson through Mr. Bates belong, 

 and which appears to be called the Guemul in Patagonia, is 

 certainly different from the animal which we received from 

 Tinta, South Peru, being of a larger size, and uniform dark 

 colour as much below as above, and the males having very 

 different horns, which are simple, with a long subbasal frontal 

 snag, indeed very like the horns of a fawn of the common stag 

 {Cervus elaphus)] but, like the other American deer, it has 

 no gland and pencil of hair on the outside of the metatarsus ; 

 and therefore I propose to describe it in the catalogues as 

 Huamela leucotis. 



In Dr. Hawkesworth's account of the voyages for making 

 discoveries in the Southern Hemisphere (3 vols. 4to, 1773), 

 Captain Wallis (vol. i. p. 388, Jan. 1767) says, when 

 in Cordes Bay, Royal Reach, Magellan Straits, "we saw an 

 animal that resembled an ass 5 but it had a cloven hoof, as we 

 discovered afterwards by tracking it, and it was as swift as a 

 deer. This was the first animal we had seen in the streight, 

 except at the entrance, where we found the guanicoes, that we 

 would fain have trafficked for with the Indians. We shot at 

 this creature, but we could not hit it ; probably it is altogether 

 unknown to the naturalists of Europe. ' 



Molina, in his ' Saggio sulla storia nat. del Chile ' (Bologna, 

 1782, 8vo), p. 320, speaks of the "Guemul or Huamel " as 

 '■^Equus hisulcus,^'' but thinks it ought to be a separate genus ; 

 he quotes in a footnote a French translation of Captain Wallis's 

 observation. In the second edition of the work, published in 

 quarto at Bologna in 1810, p. 262, the account of Captain 

 Wallis is embodied in the text, the whole of the account of 

 the animal is rather altered, and the name Equus bisulcus is 

 left out.
