1900.] ON MAMMALS FROM SIAM. 191 



3. On a Collection of Mammals from Siam made by 

 Mr. T. H. Lyle. By J. Lewis Bonhote l . 



[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 

 Sclurus finlaysoni, which apparently varies irrespective of the 

 ordinary causes, such as locality, altitude &c, which usually induce 

 variation. The specimens of Belictis and Rliizomys are also of 

 great interest, and will be of much assistance to the correct under- 

 standing of these groups. Nan, the centre of the locality from 

 which these specimens come, lies on the head-waters of the 

 Menam Biver in lat. 18° 40' N., long. 101° 30' E., and the other 

 localities mentioned are near there.
