is claimed may with some degree of reason be looked upon as distinctly, 

 though indirectly, introduced by wind.* 



The species for which this mode of introduction is conceivable are 

 given below. That many of them must be introduced species their pre- 

 sence in Narcondam and Barren Island testifies ; it is therefore, as regards 

 these, somewhat on the principle of exclusion that they are referred to 

 this class, and for some of them, such as Ahrus precatorius, it is doubtful 

 if it be not rather the sea that is responsible for their appearance,

* That there is nothing extravagant in claiming this as a possible means of 

 introduction, the following passage (which refers, as it happens, to one of the 

 islands under discussion), will sufficiently prove : — " Mr. Hawkins told us that when 

 " the storm was over ************ 

 " every hollow of the island was tenanted by hundreds of numbed or wounded 

 " sea-birds of all descriptions (such as he had never seen near the island before or 

 " since) so terrified or exhausted that he picked up or took home several of them to 

 " the light-house to show to his wife. Mixed with these were a certain number 

 "of pigeons, parrots, and other land-birds, but the great majority were Petrels, 

 " Terns, Whale-birds and such like sea-fowl with which his experience as a sailor 

 " in southern seas had made him familiar. Most of these birds ultimately recovered 

 " and left the island, but many of them hung about it for weeks, and for many 

 " days remained so tame that they would not move from the ground or the rocks,
