80 ON A COLLECTION OF BIEDS FROM N. E. SUMATRA. 



(iii). Mountain land from 450-2,000 m. (1,400-6 500 

 feet). 



(iv). The Karo Tableland. 

 Under (i) which is bordered on its seaward face by bakau (man- 

 grove) forests fall the collecting stations Polonia, Mabar and 

 Tanjong Morawa. They are tobacco estates, mainly fallow land, 

 covered with young scrub and lalang grass. One eighth of an 

 estate is planted per annum and after that lies fallow for seven 

 years. Along the Batang Koewis (Tanjong Morawa), the boun- 

 dary river between Deli and Serdang, is a strip of old jungle, where 

 a number of birds were collected as also in the kampongs (villages) 

 along the river. In various places are swamps. Characteristic of 

 the district are tall tualang trees (Eoompassia sp.). 



(ii). Hill land up to about 200 m. (650 feet) which is almost 

 the limit of tobacco cultivation, is mostly without forest, Above 

 that level the terrain has been largely felled by Battaks but there 

 are still patches of big forest ; the country is also characterised by 

 steep ravines and slopes. In this region are the collecting stations, 

 Deli Toewa, Toentoengan and Gambir. 



(iii). On the south side at about 700 m. (2,275 feet) begins 

 old forest which stretches across the chain of the Karo Mts. (2,000 

 mm. 6,500 feet) to the Karo Tableland. On the north side lies 

 Bandar Baroe, on the Medan-Toba road at the foot of Mt. Sibajak, 

 at the entrance to the Tengkeh Pass. Birds collected there come 

 from the north slopes of Mt. Sibajak, at a height of 1,000-1,400 m. 

 ( 3,250-4,550 feet). At the highest point of the pass is Tengkeh 

 (1,430 m.) (4,650) with magnificent high old forest, 



(iv). Karo Tableland is covered with lalang grass and sur- 

 rounded by mountains often 1500 m. (4875 feet) in height. Trees 

 are to be found in deep ravines and in the native villages. On the 

 tableland is also occasional Battak cultivation. On the north side 

 lies Brastagi. Birds from that locality were collected on the 

 southern slopes of the Karo Mts., on the tableland itself, and in 

 the villages." 



In addition to those obtained by Heer van Heyst the following 

 species appear in the list published by Messrs. de Beaufort and de 

 Bussy regarding which the following notes may be of interest. The 

 numbers prefixed are those of the authors, appended ones are from 

 our own list. (Journ. Fed. Malay States Mus. VIII. pt. 2, 1918.

4. Lophura rufa (Baffles). 

 6. Argusianus argus (Linn.).

 (Baffles). '
