234 APPENDIX. 



(vol. iv. p. 402) led me to doubt the existence of reefs ; un- 

 coloured. 



The coast of Malacca, Tanasserim, and the coasts north- 

 ward, appear in the greater part to be low and muddy : where 

 reefs occur, as in parts of Malacca Straits, and near Singapore, 

 they are of the fringing kind ; but the water is so shoal, that I 

 have not coloured them. In the sea, however, between Malacca 

 and the west coast of Borneo, where 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, 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 (Horsburgh, 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 Beat, in Gaspar Strait, Lucepara and Cari- 

 mata ; 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 by 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 autho- 

 rized 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,
