on the island ; but, though these must 

 necessarily have rendered the pigs 

 shy, it can hardly be supposed that 

 they have exterminated them. 

 Table Island ; cultivated. Great Coco ; in 

 the old garden and also plentiful all 

 over the clearing ; apparently quite 

 naturalised. 



Table Island ; cultivated, and as an es- 

 cape. Great Coco ; very plentiful and 

 spi'eading far into the jungle. 



Both islands ; common in the clearings. 



Table Island ; only in the clearing ; not 

 plentiful and as it is not met with in 

 Great Coco is probably here, as it 

 often is, an introduced weed. But it 

 need not always be so since the species 

 is abundant on bare rocky promon- 

 tories at the south end of Rutland 

 Island where introduction by human 

 agency is not to be thought of. 



Great Coco ; this species is not present 

 on Table Island apparently, and on 

 Great Coco it was only found on the 

 isthmus connecting the north-eastern 

 peninsula — where the clearing is — with 

 the main island. But the species does 

 not occur in the clearing, and it is re- 

 markably abundant where it occurs. 

 Moreover it is exceedingly abundant in 

 Diamond Island, off the Arracan Coast, 

 which is another section of the same 

 island chain ; the writer is therefore 

 inclined to believe that the species 

 does not owe its introduction to hu- 

 man agency but that it may be classed 

 among the remanent species.] 



In all three islands, common on rocky 

 promontories and bare isolated rocks 

 though a frequent weed of cultivation 

 this owes its presence here, not to 

 human influence, but to the agency of
