Only nine specimens were collected representing eight different 
species. 
‘he 
we) 
Macacus nemestrinus, Linn. 
One male, rather darker than usual, from the Madihit, 
May. A common monkey in South Burma, Malay Peninsula, 
Sumatra and Borneo. 
Semnopithecus hosei, Thos. 
One female from Salindong, June. A species apparently 
confined to the Baram and Limbang districts. ‘The type was 
taken at Niah on the Sarawak coast. 
Viverra tangalunga, Gray. 
One from Salindong, June. Common. 
Tupaa montanus, Thos. 
One example from Mt. Selinguid, alt. 4,500 ft. cire. 
Compared with three from Mt. Dulit, the median blackish band 
is not fully developed and the sides lack the rufous tint of adult 
specimens. Mr. H. C. Robinson kindly examined it and agrees 
in this identification. 
Rhithrosciurus macrotis, Gray. 
One example from the Madihit district. Found in low- 
lying districts in Sarawak up to some 2000 ft. Not recorded 
outside Borneo. 
Scirus prevostu, Desm. 
One from Limbang, June. ‘Typical dark-grey backed 
form. One of the commonest squirrels in Sarawak. 
Sciurus notatus, Bodd. 
One from Mt. Derian, alt. 4,500-5,000 ft. May—and one 
from Limbang in June. ‘The Mt. Derian specimen agrees best 
with some from Mt. Dulit, but has a darker tail than any from 
that locality ; the black band on each side of the belly is wider 
than in any Dulit specimen in the Museum. ‘The underneath 
is rich reddish hke-the Dulit form. The Limbang example 
agrees with those taken near Kuching. A common squirrel 
all over Sarawak. 
Cervulus muntjac, Zimm. 
A male from Salindong. Common.
