These birds were moulting. As compared with specimens 
from the mainland, I agree with Mr. Clark as to the colour 
of the plumage and the measurements of wing and tail.

This bird is met with everywhere along the flat coast-belts 
of cactus-scrub. Mr. Richmond (/. c.) considers the 
Margarita bird to be a little smaller than those from the 
mainland. 
I find that the wing in my series varies as follows :— 
4g adults, Margarita Island, from 2°7 to 2°8 inches.
