548 PROCEEDINGH OF THE NATIONAL. MUSEUM. vol. xxxiii. 



rivers traverse a country characterized by low hills. See map, frontis- 

 piece, where most of the points visited by Doctor Abbott are shown. 

 Doctor Abbott's remarks on the places visited by him follow: 



The Sungei Sama is one of the two branches of the Ambawang which flows into the 

 Landak River, 2 miles above Pontianak. This river is inhabited by Dyaks, who have 

 been accustomed to shoot for natm-alists at Pontianak, and that is the reason for my 

 comparative success during my short stay. I stayed at the Kampong of the Mankoh 

 (h(>adman), 18 miles from Pontianak. Tlie district is all swampy, and the big jungle 

 is cleared immediately along the river for a half mite Ijack. There are many sago plan- 

 tations. Beyond a half mile from the river bank is heavy forest. The headwaters of 

 the Rama are on some hills, and here is where the two Orangs were shot. The Dyaks 

 live in the reguhu- long hous(\s (Rnmeli P;iiij(ing) of the Dyaks, but are otherwise much 

 Malay i tied. 



The country along the Landak River for the lower 50 miles of its course is swampy 

 and still mostly heavy forest. The last kampong (village) is about 14 miles from Pon- 

 tianak, and from here, to Batu Ampar the banks are mostly heavy forest. Above this 

 point the banks become higher and the country largely covered with scrub jungle and 

 lalang, and is inhabited by a considerable population of Dyaks. A good many Malays 

 inhal)it the district about Ngabong and along the river. 



About Sanggau the country is mostly rolling, with low hills. Not much heavy forest 

 is left, mostly scrub jungle and lalang with small patches of heavier forest. The Sak- 

 aiam River flows into the Kapuas at this point, coming down from the borders of Sara- 

 wak. There is a consideral)le population of Malays along the l:)ank and many Dyaks 

 in the district. I went iip the Sakaiam as far as Mrowi. alxmt 105 miles. Scarcely 

 any heavy forest is left near the river; all scrub and lalang. A good deal of heavy 

 forest remains along its aflluent, the Kumbaiang River. Along its upper course, but 

 not upon its banks, are many hills which are still forest clad, especially near the Sara- 

 wak border. I was told much rimlia (virgin forest) exists along the .Tangko, the first 

 l^ranch of the Sakaiam above Sanggau. 



What I saw of Borneo np the Kapuas was a poor place for collecting. Down the i-iver 

 in the swampy forests there were som(» animals, the inhabitants being Malays or 

 Dyaks who did not eat monkeys. But every Dyak has a gun in Borneo, and up 

 river everything having fur, fin, or feather is devoured. Sarawak being a native State, 

 the natives are allowed firearms, and as a consequence guns and ammunition drift across 

 the frontier all over Dutch Borneo. The Dutch authorities complain very much about 

 it. In Sumatra one may occasionally see an old gun, but ammunition is almost 

 unobtainable. 



SYSTEMATIC LIST OF SPECIES. 



The mammals collected by Doctor Abbott represent thirty-eight ' 

 species or subspecies, five of which were previously unknown to 

 science, two of them being here described for the fh'st time. A 

 systematic list of all the species collected, accompanied by tables 

 giving the precise localities and measurements of the individual 

 specimens, with Doctor Abbott's field observations, follows: 



MANIS JAVANICA Desmarest.

Two specimens from Pontianak, a young and an adult male. The 

 skull of the adult appears to be the oldest Manis skull in the United 

 States National Museum. The zygomatic arch is complete and bony
