islands are at the outer verge of the reef, and maybe passed 
within a quarter of a mile ; the north-east island is in latitude 
11° 44' 15% and longitude 142° 58' 45". 
Me. ARTHUR'S ISLES consist of four low bushy islets, 
of which two are very small; they are encompassed by a 
reef of more than three miles long, and are separated from 
the Bird Isles by a channel three miles and a half wide. 
HANNIBAL’S ISLES are three in number, low and co- 
vered with bushes, the easternmost is near the extremity of 
the reef encircling the whole, and is in latitude 11° 34' 15", 
and longitude 142° 51' 20 f." 
V and w ; these shoals are separated by a safe channel of a 
mile and a quarter wide ; v is circular, and has a dry sand 
at its north-west edge, and a rocky key at its south-west 
end ; the channel between it and Hannibal’s Islands is two 
miles and a half wide : w is nearly four miles long, and is 
entirely covered ; the course between them is west, but, by
