 210 mm.; tail, 154; hind foot (without claws), 39. Usual measure- 

 ments of adults: Head and body, 170-180; tail, 145-155; hind foot,

 individual measurements, see table below. 



Remarks. — Tupaia lucida is a very distinct member of the splendi- 

 dula group, at once distinguished from the Bornean form by its much 

 lighter and brighter color. It is a much more highly differentiated 

 form than T. natunse, probably owing to the smaller size of the island 

 it inhabits, and the greater distance of the island from Borneo. 



Specimens examined. — Eight. All from Pulo Laut. See table 



below.
