PACIFIC OCEAN. 205 



not coloured. — Bearson, or Grand Duke Alexander's (10° S., 

 161° W.) : an atoll, of which a plan is given by Belling- 

 hausen; blue.— Souvoroff Islands (13° S., 163° W.) : Ad- 

 miral Krusenstern, in the most obliging manner, obtained for 

 me an account of these islands from Admiral LazarefF, who 

 discovered them. They consist of five very low islands of 

 coral formation, two of which are connected by a reef, with 

 deep water close to it. They do not surround a lagoon, but 

 are so placed that a line drawn through them includes an oval 

 space, part of which is shallow ; these islets, therefore, probably 

 once (as is the case with some of the islands in the Caroline 

 Archipelago) formed a single atoll; but I have not coloured them. 

 —Danger Island (10° S., 166° W.) : described as low by Com- 

 modore Byron, and more lately surveyed by Bellinghausen ; it 

 is a small atoll with three islets on it ; blue. — Clarence Island 

 (9° S., 172° W.) : discovered in the Pandora (G. Hamilton's 

 Voyage, p. 75) : it is said, ' In running along the land, we saw 

 several canoes crossing the lagoons ; ' as this island is in the 

 close vicinity of other low islands, and as it is said that the 

 natives make reservoirs of water in old cocoa-nut trees (which 

 shows the nature of the land), I have no doubt it is an atoll, 

 and have coloured it blue.— York Island (8° S., 172° W.) is 

 described by Commodore Byron (chap. x. of his Voyage) as 

 an atoll ; blue. — Sydney Island (4° S., 172° W.) is about three 

 miles in diameter, with its interior occupied by a lagoon (Captain 

 Tromelin, Annal. Marit. 1829, p. 297) ; coloured blue. — Hull 

 Island is situated 60 miles to the west of Sydney Island, and 

 is described by Wilkes (IT. S. Exploring Expedition, vol. iii., p. 

 369) as a lagoon-island ; coloured blue. — Phoenix Island (4° S., 

 171° W.) is nearly circular, low, sandy, not more than two 

 miles in diameter, and very steep outside (Tromelin Annal. 

 Marit. 1829, p. 297) : it may be inferred that this island 

 originally contained a lagoon, but I have not coloured it. — 

 New Nantucket (0° 15' N., 174° W.) : from the French chart 

 it must be a low island ; I can find nothing more about it, or
