210 APPENDIX. 



the group, so have left them uncoloured. — Malayta Isld. in 

 a rough MS. chart in the Admiralty has its northern shore 

 fringed. — Ysabel Isld., the N.E. part of this island, in the 

 same chart, is also fringed : Mendana, speaking (Burney, 

 vol. i. p. 280) of an islet adjoining the northern coast, says 

 it is surrounded by reefs ; the shores, also, of Port Praslin 

 appear regularly fringed. — Choiseul Isld. ; in Bougainville's 

 Chart of Choiseul Pay, parts of the shores are fringed by coral- 

 reefs. — Bougainville Isld. ; according to D'Entrecasteaux the 

 western shore abounds with coral-reefs, and the smaller 

 islands are said to be attached to the larger ones by reefs ; 

 all the before-mentioned islands have been coloured red. 

 Bouka Islds. ; Capt. Duperrey has kindly informed me in a 

 letter that he passed close round the northern side of this 

 island (of which a plan is given in his atlas of the Coquiltes 

 voyage), and that it was " garnie d'une bande de recifs a 

 fleur d'eau adherentes au rivage ; " and he infers, from the 

 abundance of coral on the islands north and south of 

 Bouka, that the reef probably is of coral ; coloured red. 



Off the north coast of the Salomon Arch, there are 

 several small groups which are little known ; they appear 

 to be low, and of coral-formation ; and some of them 

 probably have an atoll-like structure ; the Chev. Dillon, 

 however, informs me that this is not the case with the B. de 

 Candelaria. — Outong Java, according to the Spanish navi- 

 gator, Maurelle, is thus characterised ; but this is the only 

 one which I have ventured to colour blue. 



New Ireland. — The shores of the S.W. point of this 

 island and some adjoining islets, are fringed by reefs, as 

 may be seen in the atlases of the voyages of the Coquille 

 and Astrolabe. M. Lesson observes that the reefs are open 

 in front of each streamlet. The Duke of York's Isld. is 

 also fringed ; but with regard to the other parts of New
