226 APPENDIX. 



edit.), speaking of the islands in Dampier Strait, says, ' sharp 

 coral-rocks line their shores ; ' coloured red. — In the sea 

 north of these islands, we have Guedes (or Freewill, or St. 

 David's), which from the chart given in the 4to. edit, of 

 Carteret's Voyage must be an atoll. Krusenstern says the 

 islets are very low ; coloured blue. — Carteret 1 s Shoals, in 

 2° 53' N., are described as circular, with stony points show- 

 ing all round, with deeper water in the middle; coloured 

 blue. — Aiou : the plan of this group, given in the atlas of the 

 Voyage of the Astrolabe, shows that it is an atoll ; and, from 

 a chart in Forrest's Voyage, it appears there is 12 fathoms 

 within the circular reef ; coloured blue. — The S.W. coast of 

 New Guinea appears to be low, muddy, and devoid of reefs. 

 The Arru, Timor-laut and Tenimber Groups have lately been 

 examined by Captain KolfF, the MS. translation of which, by 

 Mr. W. Earl, I have been permitted to read, through the 

 kindness of Captain Washington, R.N. These islands are mostly 

 rather low, and are surrounded by distant reefs (the Ki 

 Islands, however, are lofty, and, from Mr. Stanley's survey, 

 appear without reefs) ; the sea in some parts is shallow, in 

 others profoundly deep, as near Larrat. From the imper- 

 fection of the published charts, I have been unable to decide 

 to which class these reefs belong. From the distance to which 

 they extend from the land where the sea is very deep, I am 

 strongly inclined to believe they ought to come within the 

 n barrier class, and be coloured blue ; but I have been forced to 

 leave them uncoloured. — The last-mentioned groups are con- 

 nected with the east end of Ceram by a chain of small islands, 

 of which the small groups of Ceram-laut, Goram, and Keffing 

 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 Arafura Sea, p. 9).
