FASCICULI MAL AT FUSES 
of which arc incorporated in the present paper, and will, I trust, prove of use 
to future workers. I must here record my thanks to Mr. Gerritt S. Miller, 
of the National Museum at Washington, who very kindly sent me over a 
series of topotypes of several of his recently described species, which have been 
of the greatest assistance. 
Two rare species of bats, whose occurrence on the Peninsula was doubtful, 
have been procured, viz., Cynopterus ecaudatus and Nycteris javanica^ and also 
several specimens of Mr. Miller’s recently described Emhallonura peninsularis. 
Several fine adult skulls and skins of the porcupine Hystrix grotei^ Gray, 
hitherto only known from the type, a young specimen, were brought back. 
They are apparently of the same species as that recorded by me in the ‘ Skeat ’ 
collection as H, yunnanensis^ which is probably identical with Gray’s species. 
Nemorhoedus swettenhami proves to be a good form distinct from iV. 
sumatrensis^ and a revision of the Tragulidae^ partly brought about by the 
series in this collection, has already been published. In addition to the actual 
specimens, the collectors have made some very interesting field-notes on the 
habits and distribution of several species, which will be found under those 
species to which they refer ; among other points, a difference in the habits of 
Sciurus vittatus and S. nigrovittatus^ which are now proved to be perfectly 
distinct species, is noted, and a curious difference between the habits of the 
former species on the East and West Coasts is pointed out. The distribution 
of species on either side of the Peninsula seems likely to be a matter of con- 
siderable interest, but at present our knowledge is too limited for any definite 
statements to be made ; as a rule, the species on either coast appear to be much 
the same, but their distribution is different ; in the case of Funamhulus insignis^ 
however, the Eastern form differs from that found on the West Coast. It has 
been found that Linnaeus’ name of cynomolgus^ for the common macaque 
could no longer stand, as it applies to an African monkey, probably a baboon, 
and in consequence, Raffles’ name of fascicularis has been used. Mr. Miller 
has been followed in the use of the generic name Presbytes instead of that of 
Semnopithecus^ in accordance with the laws of priority. 
It only remains for me to tender my best thanks to Mr. Oldfield Thomas, 
who has so greatly helped me with his advice and opinion on the difficult points 
which arose during the writing of this paper. 
Hylobates sp. (?) 
‘ We never actually saw a gibbon except doubtfully, at a great distance, 
on Bukit Besar, but we frequently heard them near Mabck, and judging from 
the noise they made they must have been very abundant on the hills round 
the Semangko Pass on the Perak Pahang boundary.’
