89. Turiiix piiiifiiax taii^oor Sykes. — 1 J ^^i 1915. 

 Iris: white. Wing: 81 mm. The Bustard Quail is rather 

 common on suitable localities throughout the Peninsula, but 

 on accoimt of their habits of living in high grass they are 

 rather seldom met with. 



90. Melaiioperdix iiigra Vig. — 1 c? V^ 1915. Iris: 

 brown. Wing: 138 mm. This species only inhabits the most 

 southern portions of the Peninsula and has not been obtained 

 much north of the latitude of Penang (viz. at about N. 6°). 



Mammals collected at Teluk Anson, Perak, and 



its neighbourhood. 



The collections received from the neighbourhood of Teluk 

 Anson in Lower Perak also contained specimens of the 

 following species of Mammals. Of course all the forms are 

 typical Malaj^an, and no novelties were met with. 



A general account of the natural condition of the land- 

 scape has already been given in the account of the Birds 

 [antea p. 7) to which it is unnecessary to refer further. 



1. Presbytis eristata Raffl. — 1 $ -/r» 1915; 1 2 juv. 

 Vö 1915. 



The Silvered Leaf-Monkey is yet known only to inhabit 

 the coast regions of Perak and Selangor. Some slightly 

 differentiated forms, however, are to be found on several of 

 the islands along the coasts of the Malay Peninsula. 



In adult specimens the pelage is sooty black, strongly 

 washed throughout with silvery white. The hands and feet 

 as well as the facial skin are pure black. The young specimen 

 in the collection is almost orange-yeilow with the exception 

 of the head, a broad line on the upper neck, the hands and 

 feet which almost have assumed the colour of the adult.
