of the island, but the mountain-forest is in character more like 
younger wild forest such as may be met with on Java or Sumatra 
At the close of this article I will refer to this point again. 
Dr. DammMermMan who is now subjecting the fauna of Krakatau 
and Sebesy to a close investigation (a preliminary survey of it 
has already been published) had paid a short visit to the island 
of Sebesy in 1920. Subsequently in 1921 a small party of natu- 
ralists consisting of Messrs Boscuma, Dammerman and Sixpers, 
who were to undertake the zoological survey, and myself, made 
an excursion to Sebesy in the research vessel “Brak’’. On our 
stay at the island I have been chiefly engaged in collecting the 
higher plants and the galls. I also managed to bring along a 
number of fungi, lichens and musci, but on such excursions 
when notes have also to be taken concerning the composition 
of the flora, it is necessary to confine oneself to some definite 
objects. I have already published a survey of the galls of the 
island '), On April 21st we started from Tandjong Priok in the after- 
noon, and on the morrow we reached the little place of Kaliando 
situated on the South-coast of Sumatra. Here we recruited half 
a dozen coolies and a guide who proved remarkably lazy. From 
there we proceeded to the N.E. side of the island of Sebesy 
where we let go the anchor. This was the starting point of our 
excursions (see the map of the island on plate XX XVII), so that 
the East side of the island could be explored with some care. 
The mountain top also was climbed from this side. On April 
27th we coasted all round the island and could only land for 
a short time on the South coast and collect a little. But on 
this coasting tour it was clear that the vegetation was pretty 
much the same everywhere; it may therefore be assumed that 
the excursions made on the East side of the island enabled us 
to form a fairly complete idea of the vegetation. 
Viewed from the ship (i.e. from the N. E.) the island of 
_ Sebesy makes an impression similar to that of Krakatau as 
regards its shape. Along the coast there is a narrow belt of 
beach and behind ‘that a narrow stretch of the Barringtonia-
