STRIPED SPINE-TAIL 215 
is pale brown, marked with fuscous; the crown 
and wing-coverts rufous. The beauty of the bird is 
in the throat, which has three strongly contrasted 
colours, distinguishing it from all other Synallaxes. 
In the angle of the beak the colour is sulphur-yellow, 
under this is a patch of velvet black, and on each 
side of the yellow and black a pure white patch. 
Mr. Barrows has the following interesting note 
on its nesting-habits: ‘‘A nest containing four 
white eggs, faintly tinted with blue, was found in a 
thorny tree, and some eight feet from the ground. 
The nest was quite similar to the one just described 
(of S. albescens), but the cavity in which the eggs 
were laid was near the top of the body of the nest, 
while the passage-way descended from it to the base 
of the nest, and there becoming external, rose gradu- 
ally to the level of the eggs at a distance of almost 
three feet.”
