﻿Aruba, Curasao, and Bonaire. 329 



no yellow feathers are to be seen on the throat, and only 

 a few scanty feathers on the upper chin are of a pale yellow. 

 In nearly all my specimens these feathers are of a more or less 

 reddish-brown colour, but this, I believe, is due only to the 

 juice of some fruit, as in one rather clean specimen they are 

 pale yellow. 



(3) While the whole of the band of the wing is yellow in 

 C. ochroptera, and only a few scanty red feathers are some- 

 times to be seen next the body, the cubital edge in C. roth- 

 schildi is bright scarlet, more or less mixed with yellow 

 outwards, but not to a great extent. 



(4) The yellow shoulder-patch is very much smaller, and 

 often quite restricted and mixed with red. The outer bend 

 of the wing is not pure yellow, but yellowish green. 



(5) The rump and abdomen show less or no blackish edges 

 to the feathers, and the abdomen is less distinctly tinged 

 with blue. 



I may add that the skulls of C. rothschildi appear to be 

 decidedly smaller, and that the bills are generally thinner 

 and the wings somewhat shorter ; but these are not very 

 decisive characters for distinguishing this species, as they are 

 not quite constant. In other respects C. rothschildi re- 

 sembles C. ochroptera. Were it not for the red cubital edge 

 and the less bluish tinge of the abdomen, C. rothschildi might 

 be said to resemble a young stage of C. ochroptera. 



The amount of scarlet at the base of the outer rectrices 

 varies, and is sometimes spread over both webs of the second 

 and third pairs of the outer rectrices. 



In one quite adult female (No. 202 of my collection) some 

 bluish feathers are visible on the forehead ; they are perhaps 

 the remains of the immature plumage, which I do not 

 know. 



Both Aruba and Bonaire must have received their Amazons 

 from the continent. On Aruba, which is so close to the 

 mainland, they have not become specialized, and very likely 

 fresh immigrants might from time to time fly over to that 

 island. Bonaire, however, is remote enough to produce a 

 new insular form.
