existence of it is doubtful; not coloured.—_Pescado_ and _Humphrey_ Islands; I can find out nothing about these islands, except that the latter appears to be small and low; not coloured.—_Rearson_, or Grand Duke Alexander’s (10 S., 161° W.); an atoll, of which a plan is given by Bellinghausen; blue.— _Souvoroff_ Islands (13° S., 163° W.); Admiral 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 Commodore 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,” page 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 (chapter 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, page 297); blue.—_Phœnix_ 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, page 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 about _Mary_ Island; both uncoloured.—_Gardner_ Island (5° S., 174° W.) from its position is certainly the same as _Kemin_ Island described (Krusenstern, page 435, Appen. to Mem., published 1827) as having a lagoon in its centre; blue.
