Show 1900.] ON MAMMALS FROM SIAM. 191 3. On a Collection of Mammals from Siam made by Mr. T. H. Lyle. By J. LEWIS BONHOTE'. [Received February 2, 1900.] (Plate XVIII.) The following is a list of a collection of Mammals made by Mr. T. H. Lyle, British Consul at Nan, in Siam. The list, as will be seen, contains the names of 20 species, one of which is new to science. The value of a collection in these days, however, is not dependent on the number of new species, but what is required is a series of specimens carefully labelled and measured in the flesh. In this respect the collection under notice is invaluable, and great praise is due to the energetic Consul, who has voluntarily collected with such care, and has generously presented the results to the National Museum. Among the objects of interest is a large series of the very variable Sciurus finlaysoni, which apparently varies irrespective of the ordinary causes, such as locality, altitude &c, which usually induce variation. The specimens of Helictis and Rhizomys are also of great interest, and will be of much assistance to the correct understanding of these groups. Nan, the centre of the locality from which these specimens come, lies on the head-waters of the Menam River in lat. 18° 40' N., long. 101° 30' E., and tbe other localities mentioned are near there. 1.
