neither clearing could be revisited in 

 1890 to enable the writer to make 

 further investigation. 



Great Coco; only one tree and that, 

 though almost certainly introduced by 

 man probably unintentionally so. 



Great Coco ; perfectly naturalised and 

 very profuse in the Coco-nut zone, 

 especiallyinthe north end of the island. 



Both islands ; extremely abundant in the 

 clearings, but also plentiful on grassy 

 slopes and bare rocky headlands of the 

 western coast of Great Coco ; it also 

 occurs on Rutland Island, at the op- 

 posite extremity of the Andaman group , 

 where introduction by man is hardly 

 conceivable : here probably it owes its 

 presence to the agency of wind.] 



Great Coco ; common on bare rocky pro- 

 montories on west side and at north 

 end of island. If introduced here it 

 has been introduced independently of 

 human agency ; it is probably a sea- 

 introduced species, but perhaps its 

 fruits may have come attached to the 

 feathers of birds.] 



Table Island ; common in the clearing ; 

 not present in Great Coco. 



Table Island ; a garden escape, but very 

 plentiful on the edges of jungle-paths 

 far from the lighthouse garden. 



Table Island ; cultivated only : has not 

 survived on Great Coco, probably 

 owing to the presence of wild pigs. 

 These the writer did not see on Great 

 Coco but their traces were abundant 

 on Table Island and the pigs them- 

 selves were obtained on Little Coco. 

 Moreover, Mr. Hume (Stray Feathers, 

 ii, p. Ill) actually met with them on 

 Great Coco. During our visits 5 or 

 6 abandoned pariah dogs were seen
