218 APPENDIX. 



to come within the barrier class, and be coloured blue ; but 

 I have been forced to leave them uncoloured. — The last- 

 mentioned groups are connected with the east end of 

 Ceram by a chain of small islands, of which the small 

 groups of Ceram-laut, Goram, and Keffi?ig are surrounded 

 by very extensive reefs, projecting into deep water, which, 

 as in the last case, I strongly suspect belong to the barrier 

 class ; but I have not coloured them. From the south side 

 of Keffing, the reefs project five miles (Windsor Earl's 

 Sailing Direct, for the Araficra Sea, p. 9). 



Ceram. — In various charts which I have examined, 

 several parts of the coast are represented as fringed by 

 reefs. — Manipa Island, between Ceram and Bourou, in an 

 old MS. chart in the Admiralty, is fringed by a very 

 irregular reef, partly dry at low water, which I do not doubt 

 is of coral-formation ; both islands coloured red. — Bourou; 

 parts of this island appear fringed by coral-reefs, namely, 

 the eastern coast, as seen in Freycinet's chart; and Cajeli 

 Bay, which is said by Horsburgh (vol. ii. p. 630) to be 

 lined by coral-reefs, that stretch out a little way, and have 

 only a few feet water on them. In several charts, portions of 

 the islands forming the Amboina Group are fringed by reefs; 

 for instance, Koessa, Harenca, and Ucaster, in Freycinet's 

 charts. The above-mentioned islands have been coloured 

 red, although the evidence is not very satisfactory. — North 

 of Bourou the parallel line of the Xulla Isles extends : I have 

 not been able to find out anything about them, excepting 

 that Horsburgh (vol. ii. p. 543) says that the northern shore 

 is surrounded by a reef at the distance of two or three miles ; 

 uncoloured. — My sol Group ; the Kanary Islands are said 

 by Forrest (Voyage, p. 130) to be divided from each other 

 by deep straits, and are lined with coral-rocks ; coloured 

 red. — Guebe, lying between Waigiou and Gilolo, is engraved
