1900.] ON TIIJE MAMMALS OF THE " SKEAT EXPEDITION." 869 



A large proportion of the insects mentioned in this paper have 

 been identified by comparison with specimens preserved at Oxford 

 in the Hope Department of the University Museum, to the 

 officials of which I offer my thanks for the ready help which 

 they have given me. I cannot conclude without expressing my 

 personal gratitude to the Siamese Government for the kindness 

 and generosity with which it treated us throughout : to the officials 

 at Bangkok and Singora who arranged for our reception in lower 

 Siam : to the Malay Bajas through whose territory we passed, 

 without whose aid the Siamese Malay States are practically a closed 

 country to Europeans : and to Luang Phrom, Commissioner of 

 Patani, to Kun Bhat Wan Hussein, and to the other gentlemen 

 who accompanied us as agents of the Siamese Government ; at 

 whose hands I received much personal kindness, and whose assist- 

 ance and advice made it possible to travel in such a country with 

 physical comfort and with some degree of celerity. 



3. On the Mammals collected during the " Skeat Expedition " 

 to the Malay Peninsula, 1899-1900. By J. Lewis

1 have the pleasure of furnishing a report on the collection of 

 Mammals made in the Malay Peninsula by Messrs. E. Evans and 

 F. E. Laidlaw, who accompanied an expedition under Mr. W. W. 

 Skeat. As might be expected, the collection, which includes 

 specimens of 54 species, is of considerable interest, although only 

 one, a rodent, appears to be new to science. A fine specimen of 

 Macacus rufescens was procured, which has hitherto only been 

 known by the type, a young example ; the presence of Trichys 

 lipura, a Bornean species about whose occurrence in this region 

 considerable doubt bad been expressed, is of great interest. The 

 collection also contains a fine skull of Hystrix yunnanensis ; a skin 

 of Mus cremoriventer, a scarce species lately described from the 

 Malay Peninsula by Mr. G. Miller, jun., of Washington ; and 

 several specimens of Vesperugo tylopus, originally described from 

 Borneo. 



As Capt. Stanley Plower has lately published a catalogue of the 

 Mammals of Siam and the Malay Peninsula, I have not given the 

 full synonymy but have referred to his paper, only adding the 

 references to one or two subsequent papers to which he did not 

 have access. Great praise is due to Messrs. Evans and Laidlaw for 

 the careful way in which they collected : almost all the specimens 

 having careful dates aud measurements, which, apart from greatly 

 adding to their value, has considerably lessened the work of 

 identification. With regard to the position of the places
