This was the only specimen of this species which I saw on 
Margarita. Neither Capt. Robinson nor Mr. Clark met 
with the bird. On Blanquilla Island, which is 60 miles 
further north and so 60 miles farther from the mainland, I 
found it extremely common in April 1906. The vegetation 
and conditions generally on the two islands, so far as this 
bird is concerned, are identical. 
Curiously enough, during a second visit to Blanquilla in 
February 1907, we only saw and shot one example of 
this form, although we covered more ground and explored 
the island more thoroughly than during our first visit. 
CHLOROSTILBON CARIBBAUS. 
Chlorostilbon caribbea Sharpe, Hand-l. B. ii. p. 118 (1900) ;

This bird does not differ from examples from other 
localities. It is common above El Valle, but although I 
saw several in one clearing I only secured one skin. 
Bucco BICINCTUS. 
Bucco bicinctus Robinson, Proc. U.S. Nat. Mus. xvii. 
p. 665 (1895) ; Clark, Auk, xix. p. 263 (1902).

c,d. ad. March 19-20, 1906. [P. R. L.] 
These birds frequent the bushes in the flats behind 
Porlemar, and I also found them in the foot-hills about 
El Valle. They sit very still and often exactly match their 
surroundings, so that one suddenly becomes aware of their 
presence on a bough. They have a surprisingly loud call- 
note: I only heard it when they were flying from one tree 
to another. 
I can find no appreciable difference between birds from 
Margarita and those from the mainland.
