Sciurus rubriventer. 



1839 — 1844. ISciurus rubriventer (Forsten) Muller and Schle- 



gel. Verhandelingen etc. p. 86. 

 1878. Sciurus bicolor Anderson. Yunnan Expedition, p. 



215 (partim). 



This species has nothing in common with Sciurus bicolor 

 as Anderson seems to believe. It is one of the best defi- 

 nited species and it is very curious that Anderson has not 

 recognized it as such. He has examined the types of al- 

 biceps, leschenaultii , auri center ^ hypohucus , bicolor var. 

 sondaica and ephippium (1. c. p 217) and although he 

 has studied the Squirrels of our collection also , he must have 

 overlooked our typical specimens of rubriventer. It is a 

 Squirrel equal in size to Sciurus hippurus and thus much 

 smaller than Sciurus bicolor, the large red ears are fringed 

 with numerous jet-black hairs and not naked as in 

 hippurus and bicolor. The belly of I'ubrirenter always is 

 red , what never is the case in bicolor. Hairs of tail black 

 with broad red rings. The skull of rubriventer is narrower 

 than that of bicolor, the nasalia being elongated and less 

 broad, moreover bicolor has one upper premolar, mean- 

 while rubriventer has two upper premolars.
