SYNALLAXIS.—SIPTORNIS. 151 
Whitely, who found this bird at San Pedro in Honduras, a short way inland from the 
coast 9, 
Our observations on this bird extend to January, August, and September, but we 
never met with the nest. This, Mr. Gaumer tells us }2, is a monstrous structure of 
large sticks, well laid together, with the entrance below and some 18 inches from where 
the eggs are placed. Mr. Gaumer thought that the bird does not build the nest itself, 
but occupies the deserted one of some other bird or animal. The Maya name for this 
species is “ Tzapatan.” The bird is active and restless in its movements, frequenting 
the lower growth of the forest. It has a harsh cry, with nothing melodious about it 
as that ascribed to S. albescens. 
SIPTORNIS. 
Synallaxis (partim), auctt. 
Siptornis, Reichenbach, Handb. p. 171 (1853) ; Scl. Cat. Birds Brit. Mus. xv. p. 58. 
Siptornis contains the species with twelve rectrices which were formerly included in 
Synallaxts, but which are better placed under a separate name. In general appearance 
the members of the genus resemble Synallaxis, but they may at once be distinguished 
by the number of their rectrices. Most of them also have the ends of these feathers 
more rounded, and the barbules of the barbs complete to the end. This, however, 
does not apply to such species as S. anthoides, &c., forming Section VI. of Mr. Sclater’s 
arrangement. 
Two species only are found in our country, both of them in Costa Rica, S. rufigenis 
being peculiar to that country. The other, S. erythrops, occurs also in the State of 
Panama and in Western Ecuador.
