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 checks 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. ]9th, 1908, after a passage of over a thousand, 

 miles from the Island of Cura9ao, 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
