PART II.
Since the publication of the first part of this paper (antea pp. 14-133), we have been favoured with a further series of birds by Heer A. C. F. A. van Heyst which, containing as it does, a considerable number of species not included in his former consignments, incrits description in detail. In addition we have received a copy of a paper by Dr. L. F. de Beaufort and Dr. L. P. de Bussy "Vogels van de Oostkust van Sumatra" (Bijdragen tot de Dierkunde uitgegeven door het Koningklijk Zoölogisch Genootschap "Naturis Artis Magistra" te Amsterdam, xxi, pp. 229 to 276 (1918?) which deals with a large collection of birds made in precisely the same localities as that of Heer van Heyst. We have quoted this article throughout as "de Beaufort and de Bussy p.—."
As the area covered by the political division known as the Sumatran East Coast Residency has now been explored in some detail, at least as regards its ornithology, we have indicated briefly the total number of species definitely known to occur in the area to which no great additions, except Limicoline, coastal and migrant forms are now to be expected, with the possible exception of such species as thrushes, warblers and white-eyes which may perhaps be found on the summits of the highest mountains above 5,000 feet which have not yet been dealt with.
We have throughout, where necessary, quoted the first part of this paper as "antea p. ."
Two new forms Pycnonotus bimaculatus baral, inhabiting West Java and the whole of the upland areas of Sumatra and Cryptolopha montis inornata, known as yet only from the Battak High lands are here described and a new name Tephrodornis pelvica frelensis given to the Wood Shrike inhabiting Eastern Sumatra and the Southern Malay Peninsula, while the additions listed raise the number of definitely recorded Sumatran species to 548.
Heer van Heyst has forwarded as the following additional account of the type of country collected over.
"The district of Deli can be subdivided into
(i). Low land up to about 100 m. (225 feet), once covered with sea.
(ii). Hill land from 100-400 m. (325-1,300 feet).
