It breeds amongst rocks and in walls, laying four white eggs thickly covered with large 
blotches of a reddish or cinnamon-brown ™. 
In Mexico Catherpes mexicanus seems to be universally distributed, from Tepic in 
the north-west throughout the central plateau to Oaxaca and Tehuantepec in the ~~ 
south; but it has not yet been detected in Guatemala, though it might not unreason- 
ably be looked for in the Altos bordering the Mexican State of Chiapas. Prof. 
Sumichrast says it is also found in the temperate region in the department of Vera 
Cruz. It builds in the houses of -Orizaba, making a skilfully-wrought nest of spiders’ 
webs, which it places in crevices of old walls or in the interstices between the tiles of 
the roofs of houses ®.

Through Mr. Lawrence’s kindness we recently had an opportunity of examining this 
interesting and distinct bird; and had the specimen been perfect, we should have 
figured it in this work. So far as we can see, Mr. Lawrence’s views as to its position 
seem correct; but this cannot be assured until the form of the tail (entirely wanting in 
the only known specimen) is known. In general appearance the bird resembles 
Catherpes mexicanus, except as regards its throat, which is rufous with a greyish tinge 
instead of white; it is also a considerably larger bird. | 
The single specimen in the Smithsonian collection was forwarded to that institution 
by Prof. F. Sumichrast, he having obtained it from Sefior T. Labarraque, who found it 
at a place in the State of Vera Cruz called Mata Bejuco. No further details of the 
species have yet come to light.

This genus was based upon a bird obtained by Tschudi in Peru, and called by him 
C. thoracicus, since supposed by several writers to be identical with Thryothorus modu- 
lator of d’Orbigny. d’Orbigny’s bird, however, is quite distinct, a most obvious 
difference being its much shorter tail. The genus itself is a remarkable one, on 
account of the peculiar form of the nostril, which is small and circular, and situated
