extend upwards on either side of the chin and throat to the 
base of the lower mandible and well on to the cheeks; the 
forehead is very pale grey, the grey gradually merging into 
the yellow of the crown, which barely extends to the centre 
of the vertex. The bases of the feathers on the forehead are 
salmon-coloured. The ear-coyerts are greenish blue, so that 
there is only a very narrow band of yellow extending below 
and beyond the eye. A few scanty feathers on the throat are 
white. ‘The cubital edge is scarlet; the yellow shoulder- 
patch is slightly mixed with red; the outer bend of the 
wing is yellowish green. The abdomen is strongly tinged 
with blue, the feathers being slightly edged with black. 
The young specimen is decidedly more green, with no 
bluish tinge on the abdomen. The distribution of the yellow 
coloration is similar, but this specimen has a yellow chin and 
throat. 
4, CHRYSOLAMPIS MOSCHITUS. 
Chrysolampis moschitus Salvin, Cat. B. xvi. p. 113 (1892) ; 
Sharpe, Hand-l. 1. p. 119 (1900) ; Hartert, Tierr., Trochili, 
p. 100 (1900). 
Four males and four females. 
These specimens differ in no way from examples from the 
mainland. 
This bird is very common on Blanquilla; but, strange to 
which is between it and the mainland 
say, in Margarita 
and only fifteen miles distant. from the latter, while 
Blanquilla is eighty miles away—I saw only one solitary 
specimen of this Humming-bird during my two visits. 
Neither Capt. Robinson nor Mr. Clarke met with the species 
on Margarita, although the conditions obtaining on the two 
islands seem to be practically identical. 
5. My1arcuvus TYRANNULUS. 
Myiarchus tyrannulus Sclater, Cat. B. xiv. p. 251; Rich- 
mond, Proc. U.S. Nat. Mus. xviii. p. 673 (1895) ; Clarke, 
Auk, xix. p. 264 (1902). 
This Tyrant-bird is fairly common on Blanquilla, but 
I shot only one specimen, an adult male. It differs from
