APPENDIX. 
there is a greater depth from 40 to 50 fathoms, I have 
coloured red some of the groups, which are regularly 
fringed. The northern Natunas and the Anambas Islands 
are represented in the charts on a large scale, published in 
the atlas of the Voyage of the Favourite [by La Place, 1831]» 
as fringed by reefs of coral, with very shoal water within them. 
Tumbelan and Bunoa Islands (1° N.) are represented in the 
English charts as surrounded by a very regular fringe. — 
St. Barbes (0° 15' N.) is said by Horsburgh (vol. ii. p. 279) 
to be fronted by a reef, over which boats can land only at 
high water. — The shore of Borneo, at Tunjong Apee, is also 
fronted by a reef, extending not far from the land (Hors- 
burgh, vol. ii. p. 468). These places I have coloured red ; 
although with some hesitation, as the water is shallow. I 
might perhaps have added Pulo Leat, in Gaspar Strait, 
Lucepara and Carimata ; but as the sea is confined and 
shallow, and the reefs not very regular, I have left them 
uncoloured. 
The water deepens very gradually from the whole west 
coast of Borneo ; and I cannot make out that it has any 
reefs of coral. The islands, however, off the northern 
extremity, and near the S.W. end of Palawan, are fringed 
hy very distant coral reefs : thus the reefs off Balabac are 
no less than five miles from the land ; but the sea, in the 
whole of this district, is so shallow, that the reefs might be 
expected to extend very far from the land. I have not, 
therefore, thought myself authorized to colour them. The 
N.E. point of Borneo, where the water is very shoal, is 
connected with Magindanao by a chain of islands called 
the Sooloo Archipelago, about which I have been able to 
obtain very little information ; Pangootaran, although ten 
miles long, entirely consists of a bed of coral-rock (Notices 
of E. Indian Arch. p. 58) : I believe from Horsburgh that 
the island is low ; not coloured . — Taliow Bank, in some 
old charts, appears like a submerged atoll ; not coloured.
