SCIURUS ANNULATUS. 25 



m.m. 



Width between the jugalia 28 



» » » orbits 15 



Length of upper molar series 9 



Distance between incisor and first upper molar . . 10 



There are four molars in each jaw. The smooth incisors 

 are of an orange or honey-yellow color. 



This species can only be confounded with Sciurus punc- 

 tatus and cepapi, but is easily distinguished from Sciurus 

 punctatus by its larger size and longer tail and by the 

 uniformly colored under parts of the body , from Sciurus 

 cepapi by its larger size and by having four molars in 

 each jaw and not five as is the case in that species. 



The type-specimen of Desmarest's Sciurus annulatus is 

 not to be found in the Museum du Jardin des Plantes. 

 According to Prof. Alph. Milne Edwards it was usual with 

 GeoS'roy to put a more beautiful specimen of the same 

 species in the place of another if the latter was in a bad 

 state of preservation and in this way the type in question 

 appears also to have been lost. Happily the description given 

 by Desmarest is so clear that there can be no matter of doubt.
