§ Introdtictort. 
The Cocos are a small group of three islands, Table Island, Great 
Coco, and Little Coco, lying about 30—45 miles north of Landfall Is¬ 
land, the most northerly of the Andaman group proper, in Lon. 93 ° 21 ' 
E., Lat. 13 ° 56 ' to 14 ° 10 ' N., and form one of the links in the island- 
chain that stretches southwards from Cape Hegrais in Arracan to the 
Nias Islands off the western coast of Sumatra. 
The first link in this chain is Diamond Island, Lon. 94 ° 18 ' E., Lat. 
15 ° 51 ' N., 8 miles south of Cape Negrais and 130 miles north-north-east 
of the Cocos; the next is the island of Preparis, (not yet botanically 
investigated), larger than Diamond Island but smaller than the Great 
Coco, 80 miles south-south-west from Diamond Island and 50 miles to 
the north of the Cocos. The strait between Diamond island and Pre¬ 
paris is somewhat under 100 fathoms, that between Preparis and the Cocos 
somewhat over that depth. The channel between the Great and the Little 
Coco is under 50 fathoms, a depth not greatly if at all exceeded in the 
passage between the Cocos and Landfall. The next link in the chain 
is the Andaman Group proper, extending from about Lat. 10 ° 40 ' to 
93
