Botoumah, 13° S., 179° E. — From the chart in 
Duperrey’s Atlas, I thought that this island was encircled, 
but the Chevalier Dillon assures me that the reef is only a 
shore or fringing one ; coloured red. 1 
Independence Island, 10° S., 179° E., is described by 
Mr. G. Bennett (United Service Journ. 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, Peyster, and Ellice Islands 
are figured in Arrowsmith’s Chart of the Pacific (corrected 
to 1832) as atolls, and are said to be very low ; blue. 2 — 
Nederlandisch Island : I am greatly indebted to the kind- 
ness of Admiral Krusenstern for sending me the original 
documents concerning this island. From the plans given 
by Captains 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. Captain 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 (Supplement au Recueil des 
Memoires Hydrograpliiques publies en 1826 et 1827, &c. &c. 
St. Petersburg, 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. — Grand 
Cocal is said in Krusenstern’s Memoir to be low, and to be 
surrounded by a reef ; it is small, and therefore probably 
' [‘ There is an extinct volcano on the island.’ — Note written in 
Mr. Darwin’s copy of this work.] 
2 [‘Mitchell Island, to the south of the Ellice group, is a very low 
atoll with about ten small islands on the reef. We were unable to 
discover any entrance to the lagoon.’ — Lieut. Chas. Smith, H.M.S. 
Fawn.]
