Hah. C\iKit\idimls\dinA. {Barwin,Sundevall); James Island (/S'MW(Z<?ra?/) ; Indefatigable, 

 Bindloe, and Abingdon Islands {Hahel). 



"This Tj'rant-bird was found on all the islands visited. It utters a feeble cry like 

 that of the preceding species. It brings its mandibles together with an audible snap as 

 they close upon its insect prey." — H. 



Genus Asio. 

 Ado galapagensis is barely sepai'able from the widely spread A. brachi/ofus, which 

 extends not only over the greater part of the Old AVorld, except Australia, but also is 

 found in North America and as far south as the Falkland Islands. Asio is also au 

 inhabitant of the Sandwich Islands.

Hah. James Island (Hanviu) ; Indefatigable Island (Hahel). 



Dr. Habel's six specimens of this Owl agree closely with one another, and with the 

 plate in the ' Zoology of the Voyage of the Beagle.' They confirm the differences 

 pointed out by Mr. Darwin between it and the well-known Short-eared Owl, to which I 

 have alluded above. This being the case, I think the species must stand under a distinct 

 title, though these differences are but slight. 



Of this bird Dr. Habel writes : — " A common species on Indefatigable, but not 

 observed by me either on Bindloe or Abingdon. I saw it on Hood's Island. Specimens 

 were covered with lice, which ran over my hands and arms as I took off the skins. 

 Under the skin, near the throat, of a male I found twenty-six parasitic worms." — H.
