man Deer; and the external is also very conspicuous in consequence 

 of the whiteness of the hairs composing it. Lord Derby's game- 

 keeper, however, stated to Mr. Gray that there are two varieties of 

 this species in Knowsley park, in one of which this tuft is much 

 more conspicuous than in the other. 



The third section comprehends those species which have a very 

 distinct tuft on the inside of the hock, but none on the outer side of 

 the metatarsus. Mr. Gray has observed this structure in two living 

 specimens of a species from Demerara in the menagerie of Lord 

 Derby, which agi-ees best with Cerv. rufus, Desm.; in another South 

 American species, allied to the former but apparently different, 

 which was presented to the Society in 1828 by Sir Philip Egerton, 

 and is now in its Museum; and in a very young spotted Fa2i'« (almost 

 a foetus) preserved in spirits in the collection of the British Museum. 

 He suspects that the Brockets of South America may have the same 

 character ; and thinks he could observe the internal tufts on the spe- 

 cimen of the Rein Deer in the Society's Museum, but no trace of 

 the external, the entire hinder edge of the metatarsus being covered 

 with a uniform very thick coat of hair. 



From an examination of the skin of the Elk in the British Mu- 

 seum, Mr. Gray is of opinion that it will probably enter into a fourth 

 section ; in as much as it appears to have very distinct tufts on the 

 inner side of the hock, and others also on the outer side of the meta- 

 tarsus about one third of its length from the heel, as in the first sec- 

 tion ; but of the existence of the latter tufts he is by no means cer- 

 tain, on account of the age and state of the specimen.
