coral-bank, which stretches about forty yards from the shore, 

 is steep to all round : in a chart, also, which I have seen, 

 the island is represented as regularly fringed. — Pnlo Mintao 

 is lined with reefs on its west side (Horsburgh, vol. ii. 

 p. 107). — Pnlo Baniak ; the same authority (vol. ii. p. 105), 

 speaking of a part, says it is faced with coral-rocks. — 

 Minguin (3 36' N.). A coral-reef fronts this place, and 

 projects into the sea nearly a quarter of a mile (Notices of 

 the India?i Arch., published at Singapore, p. 105). — Pulo 

 Brassa (5 46' N.). A reef surrounds it at a cable's length 

 (Horsburgh, vol. ii. p. 60). I have coloured all the above- 

 specified points red. I may here add, that both Horsburgh 

 and Mr. Moor (in the Notices just alluded to) frequently 

 speak of the numerous reefs and banks of coral on the west 

 coast of Sumatra ; but these nowhere have the structure of 

 a barrier-reef, and Marsden (History of Sumatra) states, 

 that where the coast is flat, the fringing-reefs extend furthest 

 from it. The northern and southern points, and the greater 

 part of the east coast, are low, and faced with mud banks, 

 and therefore without coral. 



Nicobar Islands. — The chart represents the islands of 

 this group as fringed by reefs. With regard to Great 

 Nicobar, Capt. Moresby informs me, that it is fringed by 

 reefs of coral, extending between 200 and 300 yards from 

 the shore. The Northern Nicobars appear so regularly 

 fringed in the published charts, that I have no doubt the 

 reefs are of coral. This group, therefore, is coloured red. 



Andaman Islands. — From an examination of the MS. 

 chart, on a large scale, of this island, by Capt. 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
