Psilorhinus mexicanus was described by Riippell from a specimen said to have been 
obtained in the State of Tamaulipas, and it appears that similar birds were met with 
by Lieut. Couch in the State of Nuevo Leon, and others at Mirador and in other parts 
of Mexico. It occurs also in Northern Yucatan, where Mr. Gaumer says that it is very 
common in the great forests, but is shy, living in flocks of twenty or more. 
In Guatemala we met with it in abundance in the lower heavily-forested portions of 
the Motagua valley, and also in that of the Polochic, both at Yzabal and Teleman, 
and can confirm the description of its habits given by other writers, both as to its 
associating in flocks and as to its extreme noisiness. 
Both Leyland and Mr. Taylor speak of it as common in Honduras, but neither of 
them brought home specimens. Mr. Wickham’s example, which formed the type of 
P. cyanogenys, was obtained on the shores of the Pearl Cay Lagoon, on the Mosquito 
coast of Nicaragua. South of Nicaragua its range includes the Pacific side of the 
continent, being found in Costa Rica, on the shores of the Gulf of Nicoya, as well as 
on the eastern slope of the mountains. 
Regarding P. cyanogenys of Sharpe, we have little hesitation in placing it here; the 
plumage of the type in the British Museum is in exceedingly faded and worn condition, 
and this has brought into prominence the malar spots, which are always present in
