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. |
