The mammals from the Malay Peninsula are 105 in number, and 
belong to 28 species, of which no less than 13 are Sciuridz, a group 
always well represented in collections made by ornithologists. As 
in the case of the other series, the greater part of this set were 
collected by Mr. Davison, although some few were obtained by 
Mr. J. Darling at Salanga and on the mainland adjoining, and by 
Mr. Syers in Salangore. 
As might be expected, these specimens, while of considerable value 
in fixing the northward and southward distribution of the species 
along the narrow Malay peninsula, belong for the most part to 
common species. There is, however, among them a specimea 
representing a beautiful new species of Sciuropterus, which I have 
dedicated to its discoverer, Mr. Davison, and there are many which 
render important service in contributiug additional information as to 
the exact localities and other particulars about the species to which 
they belong. 
The only previous paper of any importance on the mammals of 
this district is that published by Dr. Theodore Cantor in 1846’, 
which gives a complete list of the species then known to occur in the 
‘* Malay Peninsula and Islands,’ but which, excellent asit is for the 
date at which it was written, is now, of course, somewhat obsolete, 
and would well bear the addition of such information as may be 
gleaned from Mr. Hume’s valuable collection. 
Many of the localities at which the collection was obtained are 
referred to or described in the two following papers :—

Western Half of the Malay Peninsula,” ‘Stray Feathers,’
