are regularly fringed by coral-reefs. Carimon Java appears 

 equally so, though it is not directly said that the reefs are 

 of coral j there is a depth between 30 and 40 fathoms 

 round these islands. Parts of the shores of Sunda Sir., 

 where the water is from 40 to 80 fathoms deep, and the 

 islets near Batavia appear in several charts to be fringed. 

 In the Dutch chart the southern shore, in the narrowest 

 part of the island, is in two places fringed by reefs of coral. 

 West of Segorrowodee Bay, and the extreme S.E. and E. 

 portions are likewise fringed by coral-reefs ; all the above- 

 mentioned places coloured red. 



Macassar Sir. ; the east coast of Borneo appears, in most 

 parts, free from reefs, and where they occur, as on the east 

 coast of Pamaroong, the sea is very shallow ; hence no part 

 is coloured. In Macassar Str., itself, in about lat. 2 S., 

 there are many small islands with coral-shoals projecting 

 far from them. There are also (old charts by Dalrymple) 

 numerous little flats of coral, not rising to the surface of the 

 water, and shelving suddenly from five fathoms to no 

 bottom with fifty fathoms ; they do not appear to have a 

 lagoon-like structure. There are similar coral-shoals a little 

 farther south ; and in lat. 4 55' there are two, which are 

 engraved from modern surveys, in a manner which might 

 represent an annular reef with deep water inside; Capt. 

 Moresby, however, who was formerly in this sea, doubts 

 this fact, so that I have left them uncoloured : at the same 

 time I may remark, that these two shoals make a nearer 

 approach to the atoll-like structure than any other within 

 the E. Indian Arch. Southward of these shoals there are 

 other low islands and irregular coral-reefs ; and in the space 

 of sea, north of the great volcanic chain, from Timor to 

 Java, we have also other islands, such as the Postillions, 

 Kalatoa, Tokan-Bessees, etc., which are chiefly low, and are
