Formicarius moniliger was discovered by M. Sallé near Cordova, in the Mexican 
State of Vera Cruz, and was described by Mr. Sclater in 18561. Sumichrast says that 
it inhabits the interior of the great woods of the hot region of that State, being common 
at Cerro de la Defensa near Potrero, reaching an altitude of 2600 feet and upwards 
above the level of the sea® M. Boucard also found it at Playa Vicente in the same 
State, and Mr. Herbert Smith at Atoyac, near the foot of the mountains between Vera 
Cruz and the plateau. 
The Yucatan bird was separated by Mr. Lawrence as /’. pallidus ®, birds from that 
country, as the name implies, being unusually pale in general colour, a very common 
feature in many forms of the birds of Yucatan. This contrast of colour is quite apparent 
when specimens from that country are placed side by side with the typical form ; but 
the difference seems to be of much less value when Guatemalan and British Honduras 
examples are mingled in the series, and it is undesirable to make any separation. 
Sumichrast says ® that /. moniliger is a shy bird. Its cry as heard at a distance is a 
series of ascending notes, not unlike, though more sonorous than, those of Catherpes 
mexicanus. It is almost always to be seen on the ground, turning over with its beak 
the dry leaves or the moss in search of insects.
