STNALLAXIS.— SIPTOENTS. 151 



Whitely, who found this bird at San Pedro in Honduras, a short way inland from the 

 coast ^. 



Our observations on this bird extend to January, August, and September, but we 

 never met with the nest. This, Mr. Gaumer tells us ^^, 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 itgelf, 

 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. 



SIPTOENIS. 



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 

 Synallaxis, 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, Sec, 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.

Siptornis erythrops was described by Mr. Sclater in 1860, from specimens obtained 

 by Eraser at Pallatanga in Ecuador ^. 



It has since been traced through the western portions of that country, and thence
