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 
occui’s 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.] 
[Adenostemma viscosum. 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.] 
15. * Ageratum conyzoides. Table Island ; common in the clearing; 
not present in Great Coco. 
* Ipomeea coccinea. Table Island ; a garden escape, but very 
plentiful on the edges of jungle-paths 
far from the lighthouse garden. 
* Ipomeea Batatas. 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 painah dogs were seen
