distributed, that it seems impossible that it could have 

 escaped our deliberate search for it. It is not found on 

 Margarita. 



Myiarchus tyrannulus (Miill.). 



Myiarchus tyrannulus Sclater, Cat. B. Brit. Mus. xiv. 

 p. 251 (1888). 



One male and four females. 



These birds agree with two specimens of M. tyrannulus 

 which I obtained on Margarita in 1906 rather than with 

 five specimens obtained on Blanquilla Island, which agree 

 with Dr. Hartert's description of his M. brevipennis. The 

 plumage both above and below is darker and richer than in 

 the latter species ; but the difference in the wing measure- 

 ments is very slight — Los Testigos specimens averaging 

 90 8 mm., while specimens from Blanquilla average 898 mm. 



The exposed culmens of 



Los Testigos specimens vary from 17 mm. to 20'5 mm.

Compared with specimens of Myiarchus oberi nugator 

 ■which 1 shot at St. Vincent and Grenada, all the measure- 

 ments of my Testigos birds are smaller, and the general 

 coloration not so rich. 



Dendrceca ruficapilla rufopileata. 



Dendroeca ruficapilla rufopileata Ridgw. Proc. U.S. Nat. 

 Mus. vii. 1884, p. 173. . 



Two males and one female. 



Fairly plentiful but in poor plumage. I have referred 

 my specimens to D. ruficapilla rufopileata rather than to 

 typical D. ruficapilla or D. r. capitalis; but with such scanty 

 material and specimens in indifferent plumage, I hesitate 

 to express any decided opinion. The Blauqudla bird must 

 undoubtedly be referred to this subspecies. It occurs merely 

 as a straggler on Margarita Island. I only saw the bird on 

 two small islets lying close to Testigo Grande,
