318 Mr. P. R. Lowe on Birds collected 
distributed, that it seems impossible that it could have 
escaped our deliberate search for it. It is not found on 
Margarita. 
Myiarchus tyranntjlus (Mull.). 
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. HarterPs 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 89‘8 mm. 
The exposed culmens of 
Los Testigos specimens vary from 17 mm. to 20*5 mm. 
Blanquilla „ „ 16*5 „ 18*5 ,, 
Curasao „ „ 17 „ 20 „ 
Compared with specimens of Myiarchus oberi nugator 
which I 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. 
Dendrceca 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 Blanquilla 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.
