 of the ^Hteness of the hairs composing it. Lord Derby s game- 

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

 thff Tpecies in knowsley park. in one of which this tuft xs much 

 mote conspicuous than m the other. _ 



The third section comprehends those species which have a very 

 distinct tuft on the inside of the hock. but none on tl^e outer side of 

 the metatarsus. Mr. Gray has observed this structure m two Imng 

 specimens of a species from Demerara m the "^^^^^'H^^^l 

 Derby. which agrees best withCerv.r./«., Desm.; m another South 

 American species, allied to the former but apparently different,

 He suspects that the Brockets of South Amenca may have the šame 

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

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

 ^eum, Mr. Gray is of opinion that it will probably enter mto a fourth 

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

 inner side of the hock. and others also on the outer side of theje^«- 

 tarsus about one third of its length from t^ie 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 statė of the specimen.
