This is a highly interesting species, since it is the only bird 
approaching the form of the British Dottrel found in any part 
of the world. This rare species lias been sent me by my friend 
Captain Sturt, who procured it during his late expedition into 
the interior of Australia, behind Adelaide.

Rather a larger species, and is distinguished from the other 
members of the genus by the sombre hue of its plumage •and 
the square form of its tail.

A new species and new form, which I first saw in the streets 
of Adelaide, where it was hopping about and presenting the 
appearance of the Sparrow in London. For this new bird I 
propose the generic and specific terms Xerophila leucopsis .
