Measurements of Skulls and Skeletons. (The Dresden Museum 

 received from Prof. Semper two skeletons (Nos. 291 and 292) of 

 a Squirrel from " Mindanao," without determination of species, 

 but I do not doubt that they belong to Sc. cagsi.) 



Number of costal vertebrae 12, of lumbar 8 (7 in no. 292), of 

 sacral 3, of caudal 26 (tail in no. 292 defective) ; Sciurus europceus 

 has after different authors 12, 7, 3 and 21-25 respectively. 



Hab. Davao, South Mindanao {Platen), "Mindanao" {Semper). 



Native name : Cagsi. 



The general coloration of this Squirrel is similar to that of the 

 widespread Sc. tenuis, Horsf., but that species is only half its size and 

 has no white on the tail. Sc. cagsi also reminds one of Sc. leucomus, 

 M. & Schl., from Celebes, in its general coloration ; but the last- 

 named species has white behind the ears, which are long-haired, and 

 reddish underparts, and offers, besides, other differences.
