the rich golden or orange-yellow on the chin and throat 
which is present in C. ochroptera, whereas in C. rothschildi 
Dr. Hartert states that no yellow feathers are to be seen on 
the throat. 
As regards, too, the red coloration of the cubital edge, 
which Dr. Hartert makes a point of distinction between the 
two species, in some of my birds it is marked, in others not 
at all. As regards the yellowish-green coloration of the outer 
bend of the wing, my specimens agree with his description, 
and in all of them the feathers of the abdomen and back 
shew black edges, while in most the abdomen is tinged with 
blue. One has some bluish feathers mixed with the yellow 
on the forehead, a character which Dr. Hartert notes as also 
occurring in one of his examples from Bonaire. I agree 
with him in thinking this a sign of immaturity. 
To add to my difficulty I have a specimen which I shot 
on the Cariaco Peninsula which more closely corresponds 
with Dr. Hartert’s description of C. rothschildi than any of 
my Blanquiila birds, and two specimens from Margarita 
Island also have green on the cheeks and sides of the face, 
whereas others I brought from this island undoubtedly 
correspond with examples of C. ochroptera. 
It would be strange if out of all the nine birds I shot on 
Blanquiila there was not one in really fully adult plumage, 
and if the series actually illustrates different phases of the 
plumages of C. ochroptera. 
Swan Islands. 
On Jan. 19th, 1908, after a passage of over a thousand 
miles from the Island of Cura£ao, we came to anchor in a 
charming little bay at the western end of these two small twin 
islands. They are situated at the western end of the Caribbean 
Sea, and lie ninety-eight miles nearly due N.E. from Patook 
Point, which is the nearest part of the mainland of Honduras. 
Although in some respects disappointing from an ornitho¬ 
logical point of view, yet no island, however small, which is 
so isolated, can possibly be altogether uninteresting. The
