An analysis of tlie table of distribution from the opposite point of 
view is given below ; from it we learn that 11 species, or 14 per cent,, 
are cosmopolitan on tropical sea-shores ; that four more are nearly cos¬ 
mopolitan, being present in both hemispheres ; that only four, so far as is 
known, are limited to the coasts of these islands, the Andamans and the 
ISTicobars; and that, excepting these four, every one of the species is found 
on the Malayan Coasts. So far then as the “ littoral ” species are con¬ 
cerned we must conclude that the flora of the Coco Gi’oup is decidedly 
Malayan.

In diacussing the iulaud “ immigrant ” species the first agency to 
be considered ,is that of winds. This influence must here be stronger
