(Thus sea-borne plants on the Chagos are 28’76 per cent, 
of the whole sea-borne flora, not of the flora of the Chagos 
themselves. The total wild flora of the Maldives is 72*72 
per cent, of the total wild flora of all the groups.) We may 
now proceed to use these figures in the same way as in 
calculating insect preferences to flowers,* subtracting the 
total percentage from the particular in each case. Thus, of 
species unintentionally introduced by man, the Chagos, 
which are furthest from the stream of traffic, have a decided 
deficiency (10*37 -20 per cent.). The Laccadives have, on the 
other hand, a decided preponderance of these plants (57*54- 
51*81 per cent.). Dealing now with the total independent
