480 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxvi. 



PuLO BanCxKARU, Banjak Islands (January 16 to 21, 1902). 



No pigs or monkeys were seen, and the natives say that none occur. 

 A number of Pteropus were seen, and at least two kinds of smaller bats, 

 but none were obtained. My Malay sailing master said that he saw a 

 red '' tupai^' on the ground. It was proba])ly the form of Tuixvia tana 

 afterwards taken on Palo Tuanku. 



Tragulus brevipes.— Several seen; only one taken. 



Sciurus pretiosus. — Common. 



Sciurus bancarus.— Very common. 



Mus firmus. — 



Mus fremens. — 



Mus lingensis.— Rats were very plentiful, but land and hermit crab^l 

 abounded to such an extent that trapping was difficult and many of tMi 

 specimens caught were ruined. 

 PuLO TuANGKiT, Banjak ISLANDS (January 22 to February 5, 11H)2). 



Tragulus russeus. — Very common. Am not certain whether there 

 are one or two forms. Three males w^eighed over 5 pounds each, bu 

 none of the females were so large. Now in Tragulus the female i: 

 con.siderably larger than the male; but no correspondingly larg. 

 females were obtained among the thirty or more that I examined 

 Most of the females were pregnant. 



Sus vittatus.— A rather .small form. Common, but only one femal 

 and an inunature male obtained. 



Sciurus ubericolor. — Conmion. 



Ratufa palliata. — 



Ratufa femoralis.— Both very common and very noisy. Often see 

 together in the same tree. When alive the brown one {femoralu 

 appears smaller than the other. 



Rhinosciurus laticaudatus. — A female was caught in a rat trap a 

 Ujong Tumbaga. 



Mus firmus. — 



Mus fremens. — 



Mus asper. — 



Mus lingensis. — All four species of Mus were common. 



Lenothrix canus. — Only one taken. 



Galeopithecus volans. — Common. 



Macacus "cynomolgus." — Common. A small form similar to that < 

 Sumatra. 



PuLO Mansalar, at entrance to Tapanuli Bat (March 2 to 1 



1902). 



A monkey, apparently identical with the Preslyytes maurus of tl 

 mainland, was observed, but no specimen could be secured. It w 

 shy and not very common. The tracks of pigs were abundant, h
