I. AN EXPEDITION TO MOUNT MENUANG 

 CASING, SELANGOR. 



''By Henry N. Ridley, F.R.S., F.L.S.; with an account of 

 the Journey by C. B. Kloss.* 



[Read 7th November, 7912.] 



[Mount Menuang Casing is 'Bukit Nyor' or 'Nuang' of local 

 maps, one of the peaks of the range which forms the backbone of 

 the Federated Malay States, and is situated within a mile of the 

 spot where the boundaries of the States of Selangor, Perak, 

 and the Negri Sembilan meet. It is 4,908 feet in height, and 

 though separated on the north from the more massive portions 

 of the main range by passes of 2,000 feet or so, it yet possesses 

 a true mountain fauna :t south of it the range becomes 

 gradually broken up into more or less isolated groups of hills, 

 few of which attain an equal altitude ; while only to those in 

 the immediate neighbourhood is the high-level fauna known 

 to extend. 



The summit of Menuang Casing itself is a somewhat 

 steep peak rising above hills of only slightly inferior altitude. 



The collection, of which Mr. Ridley treats below, was 

 made in the course of a four or five days' visit in February, 

 1912. At 6 o'clock one morning I left Dusun Tua ^in the Ulu 

 Langat district of Selangor, 17 miles from Kuala Lumpur), 

 which is a rest-house near some hot springs impregnated with 

 sulphuretted hydrogen, and at 5.45 P.M. made camp on a hill- 

 side 2,950 feet high. The day's march had been an extremely 

 hard one (owing to the many descents we had to make before 

 finally attaining this altitude), and we all arrived thoroughly 

 exhausted, but I felt little compunction in getting the utmost 

 out of the Sakais who acted as carriers, since they had 

 refused to remain with me for more than one night, and had 

 stood out for most extortionate remuneration. 



Our palm-leaf shelter was made on the mountain-side on 

 a flat knoll which the Sakais called Bukit Pengaseh, and even 

 at that moderate altitude we found the nights extremely cold 

 owing to the presence of a strong wind which blew uninter- 

 ruptedly across the ridge; at midday the thermometer generally 

 indicated about 70°,
