 brownish or reddish tiuge prevails : they must be regarded 

 as moulting stages.

There are four molars in each jaw. Upper incisors orange 

 or yellowish red : they are longitudinally grooved. The depth 

 however of this groove varies considerably. In some speci- 

 mens another depression is to be found close to the inner 

 border of the upper incisors , as Gray and Peters have 

 remarked .

It frequents the woody banks of the rivers. 



The type of Sciurus auhryi Alph. Milne Edwards is a 

 young individual and Prof. A. Milne Edwards told me that 

 he did not believe it to be a good distinct species , but 

 that it is the young of Sciurus rufo-hrachiatus , in which 

 opinion I entirely agree with him. Macro.vus isahellinus Gray 

 also belongs to this species. I have examined the verv 

 incomplete skull, but could clearl}^ make out that there 

 is no trace of a fifth molar in the upper jaw and that the 

 upper incisors show a slight groove.
