2. On some Mammals from Mount Dulit^ North Borneo. 

 By Oldfield Thomas. 



[Eeceived February 20, 1892.] 

 (Plates XVIII. & XIX.). 



In 1889 I had the honour of presenting to the Society a paper on 

 the Mammals of Mount Kina Balu, the highest mountain in Northern 

 Borneo, and one previously quite unexplored zoologically. Thanks 

 to the energy of Mr. Charles Hose, a gentleman who has already 

 distinguished himself by his discoveries in the district of Baram, 

 N.E. Sarawak, I am enabled now to give an account of some Mammals 

 collected on Mount Dulit, a mountain about 9000 feet in altitude, 

 standing at the head of the Baram River. 



In the autumn of last year Mr. Hose made a successful expedition 

 up Mount Dulit, collecting a large number of specimens at altitudes 

 of from 2000 to 5000 feet, and thereby affording us a very good idea 

 of the fauna of the mountain. 



On the whole, judging from the present collection, it may be said 

 that the Mammal-fauna of Dulit is very much the same as that of 

 Kina Balu, there being no instance of a representative but different 

 species \ while two of the peculiar Kina Balu species reappear here 

 on Dulit. In all probabiUty, therefore, we may look upon Mr. Hose's 

 valuable collection as supplementary to that of Mr. Whitehead, and 

 may expect that in time most of the members of both the collections 

 will he found to occur on both the mountains. This is the more 

 likely as the collections were made at very diflFerent seasons of the 

 year, when different forms of animal life would be en evidence. Thus 

 Mr. Hose's collection is especially rich in Tupaice, of which two are 

 new, while Mr. Whitehead's was equally rich in Rats, Mice, and 



^ In the case of the birds, however, Calyptomena hosei, Sharpe, represents C. 

 whiteheadi, Sharpe, and Harpactes dtditensis, Grant, represents H. oreskios, the 

 latter occurring in Malacca, Sumatra, and Java as well as on Mt. Kina Balu.
