INTRODUCTORY NOTE 
A lthough from so rich a region, it will be seen that our collection of 
mammals embraces only some sixty-four species, of which several are 
represented by unique specimens. This is, perhaps, to be explained by 
the fact that I was only able to devote a small proportion of my time to this group, 
and also because we were not successful in securing the assistance of natives 
who were good jungle men. From time to time we set a very large number 
of traps, but found that the animals, when captured, were frequently either 
removed by small carnivores or else spoilt as specimens by ants. An efficient 
trap which will capture small mammals alive has, apparently, yet to be invented. 
In the districts visited by us I have little doubt, from my own observation, 
that there are a considerable number of small insectivores, shrews and the like, 
as well as a great variety of rats and mice, which can only be obtained by the 
merest accident by a collector who is not prepared to spend the great propor- 
tion of his time on the group. The Chiropterous fauna, too, must be very 
extensive, and I may mention that in the limestone caves near Kuala Lumpur 
I obtained, in one morning, twelve species, including the rare Eonycteris spelaea^ 
which number could doubtless be increased by systematic collecting. 
I have added to Mr. Bonhote’s paper certain field-notes made by 
Mr. Annandale or myself, which are distinguished by being placed between 
inverted commas. 
A complete set of all species obtained, including the types of new species, 
has been deposited in the National Collection.
