Rotoumah) 13 S., 179 E. — From the chart in Duperrey's 

 atlas, I thought this isl. was encircled, and had coloured it 

 blue, but the Chev. Dillon assures me that the reef is only 

 a shore or fringing one ; red. 



Independence Isl., io° S., 179 E., is described by Mr. G. 

 Bennett {United Service Jonrn., 1831, part ii. p. 197) as a 

 low island of coral-formation; it is small, and does not 

 appear to contain a lagoon, although an opening through 

 the reef is referred to. A lagoon probably once existed, 

 and has since been filled up ; left uncoloured. 



Ellice Group. — Oscar y Peyster, and Ellice Islds. are 

 figured in Arrowsmith's chart of the Pacific (corrected to 

 1832) as atolls, and are said to be very low; blue. — 

 Nederlandisch Isld. I am greatly indebted to the kindness 

 of Admiral Krusenstern, for sending me the original 

 documents concerning this island. From the plans given 

 by Capts. Eeg and Khremtshenko, and from the detailed 

 account given by the former, it appears that it is a narrow 

 coral-island, about two miles long, containing a small 

 lagoon. The sea is very deep close to the shore, which is 

 fronted by sharp coral-rocks. Capt. Eeg compares the 

 lagoon with that of other coral-islands; and he distinctly 

 says, the land is "very low." I have therefore coloured 

 it blue. Admiral Krusenstern {Memoir on the Pacific^ 

 Append., 1835) states that its shores are 80 feet high; this 

 probably arose from the height of the cocoa-nut trees, with 

 which it is covered, being mistaken for land. — Gran Cocal 

 is said in Krusenstern's Memoir to be low, and to be 

 surrounded by a reef; it is small, and therefore probably 

 once contained a lagoon; uncoloured. — St. Augustin. 

 From a chart and view of it, given in the Atlas of the 

 Coquiltes Voyage^ it appears to be a small atoll, with its 

 lagoon partly filled up ; coloured blue.
