blue. — Baivaivai, or Vivitao : Mr. Williams informs me 
that the reef is here distant from the shore ; Mr. Ellis, 
however, says that this is certainly not the case on one 
side of the island ; and he believes that the water within 
the reef is not deep ; hence I have left it uncoloured. — 
Lancaster Reef, described in Naut. Mag. 1833 (p. G93), as 
an extensive crescent-formed coral-reef, has not been 
coloured. — Rapa, or Oparree : from the accounts given of 
it by Ellis and Vancouver, there does not appear to be any 
reef. — I. de Bass is an adjoining island, of which I cannot 
find any account. — Kemin Island : Krusenstern seems 
hardly to know its position, and gives no further par- 
ticulars. 
Islands between the Low and Gilbert Archipelagoes 
Caroline Island (10° S., 150° W.) is described by Mr. 
F. D. Bennett (Geograph. Journ. vol. vii. p. 225) as con- 
taining a fine lagoon ; coloured blue. Westward of Caroline 
Island, a small lagoon-island is described in the U.S. 
Exploring Expedition in lat. 10° S. and 152° 22' W. long. ; 
coloured blue. — Flint Island (11° S., 151° W.) : Krusen- 
stern believes that it is the same with Peregrino, which is 
described by Quiros (Burney’s Chron. Hist. vol. ii. p. 283) 
as ‘ a cluster of small islands connected by a reef, and 
forming a lagoon in the middle ; ’ coloured blue. — Wostock 
is an island a little more than half a mile in diameter, and 
apparently quite flat and low, discovered by Bellingshausen; 
it is situated a little west of Caroline Island, but it is not 
placed on the French charts ; I have not coloured it, 
although I entertain little doubt, from the chart of Bellings- 
hausen, that it originally contained a small lagoon. — Pen- 
rhyn Island (9° S., 158° W.) : a plan in the atlas of the 
First Voyage of Kotzebue, shows that it is an atoll, which 
according to Wilkes (U.S. Exploring Expedition, vol. iv. 
p. 277) is nine miles in length ; coloured blue. — Starbuck
