About the hamular process of the pterygoideum it is stated that in T. macrotis it 

 has a more pronounced bend or angle on its inferior aspect, and the tip. instead of 

 ending in a point barely in contact with the audital bullse, is considerably thickened 

 and generally in contact with the bulla. The lachrymal bone is stated to be longer 

 in the Bornean form (8 — 9 mm.) against 4 — 5,5 mm. in the Sumatran animal. 



In the specimen of the present collection the collectors measurement of the ear 

 is 29 mm, thus even slightly longer than the recorded measnrements of the ear in 

 T. macrotis. Unfortunately I have been unable to examine any specimens from 

 Sumatra, but in Mr. Lumholtz' specimen the hamular process of the pterygoid bone 

 is considerably thickened and perfectly in contact with the audital bulla. In the

lachrymal bones the sutures are quite obliterated, so it is impossible to give any 

 measurements about their length. According to these statements it seems that the 

 Bornean and Sumatran animals are perfectly similar, and therefore I think Miller's 

 name will only become a synonym of Trichys lipura Gunther. 



The Malay Peninsula is inhabited by still another form Trichys fasciculata 

 Shaw. as has been shown by Bonhote (Proc. Zool. Soc. London, 1900, p. 881) and 

 by Jentink (Notes Leyden Mus., vol. 16, 1894, p. 207).
