3. A Nominal List of the Mammals inhabiting the 

 Bornean Group of Islands. By A. H. Everett, C.M.Z.S. 



[Received May 2, 1893.] 



As no complete catalogue of the Mammals of Borneo and 

 Palawan appears to be available for the use of Oriental Zoo- 

 geographers, whilst a considerable number of new species have 

 been I'ecorded of recent years, the notices of which are scattered 

 among various scientific serials, it is hoped that the present list, 

 although a merely nominal one, may not be without its use. 



I have elsewhere^ detailed the evidence \\hich seems to render 

 it necessary that Palawan should be treated as forming an integral 

 part zoologically of the Bornean group of islands. The area of 

 the Bornean group as a whole may be defined, therefore, for the 

 purpose of the present list, by the same limits as those M'hich J 

 have adopted in a list of the Birds of Boi'neo and Palawan^, -viz., 

 by a line which starts from a point immediately to the west of 

 St. Julian I. in the Tambelan Archipelago, and, being drawn south 

 of the (Ireat Natuna (Bungoran I.), passes northward of Labuau 

 aud theuce follows the 100-fathom line so as to embrace Balabac, 

 Palawan (Paragua), the Calamianes, and the Cuyo Islands, and, 

 returning along the same line of soundings on the southern side of
