ANDAMAN ISLANDS.—From an examination of the MS. chart, on a large scale, of this island, by Captain Arch. Blair, in the Admiralty, several portions of the coast appear fringed; and as Horsburgh speaks of coral-reefs being numerous in the vicinity of these islands, I should have coloured them red, had not some expressions in a paper in the “Asiatic Researches” (volume iv., page 402) led me to doubt the existence of reefs; uncoloured. The coast of _Malacca_, _Tenasserim_ and the coasts northward, 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 forty to fifty 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 (volume ii., page 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, volume ii., page 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.
