5 to 12 feet water within them; coloured red.— Jamaica : 

 judging from the charts, about fifteen miles of the S.E. 

 extremity, and about twice that length on the S.W. ex- 

 tremity, and some portions on the S. side near Kingston and 

 Port Royal, are regularly fringed, and therefore are coloured 

 red. From the plans of some harbours on the N. side of 

 Jamaica, parts of the coast appear to be fringed; but as 

 these are not represented in the charts of the whole island, 

 I have not coloured them. — St. Domingo : I have not been 

 able to obtain sufficient information, either from plans of 

 the harbours, or from general charts, to enable me to 

 colour any part of the coast, except 60 miles from Port 

 de Plata westward, which seems very regularly fringed; 

 many other parts, however, of the coast are probably 

 fringed, especially towards the eastern end of the island. 

 — Puerto. Rico : considerable portions of the southern, 

 western, and eastern coasts, and some parts of the 

 northern coast, appear in the charts to be fringed ; 

 coloured red. Some miles in length of the southern 

 side of the Island of St. Thomas is fringed ; most of 

 the Virgin Gorda Islands, as I am informed by Mr. 

 Schomburgk, are fringed ; the shores of Anegada, as well 

 as the bank on which it stands, are likewise fringed ; these 

 islands have been coloured red. The greater part of the 

 southern side of Santa Cruz appears in the Danish survey 

 to be fringed (see also Prof. Hovey's account of this island, 

 in Silliman's Journal, vol. xxxv. p. 74) ; the reefs extend 

 along the shore for a considerable space, and project rather 

 more than a mile ; the depth within the reef is three 

 fathoms ; coloured red. — The Antilles, as remarked by Von 

 Buch (DescriJ>. lies Canaries, p. 494), may be divided into 

 two linear groups, the western row being volcanic, and the 

 eastern of modern calcareous origin ; my information is very
