3. A Nominal List of the Mammals inhabiting the 

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



[Eeceived 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 recorded of recent years, the notices of ^^'bich are scattered 

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

 although a merely nominal one, may not be ^\•ithout its use. 



I have elsewhere^ detailed the evidence which seems to render 

 it necessarv that Pala\ian 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 which J 

 have adopted in a list of the Birds of Borneo and Palawan", xaz.. 

 by a line which starts from a point immediatelj' to the west of 

 St. Julian I. in tlie Tambeian Archipelago, aud, being drawn south 

 of the Grreat ISTatuna (Bungorau I.), passes northward of Labuan 

 and thence 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
