Psilorhinus mexicanus vpas 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 Eica, on the shores of the Gulf of Nicoya, as well as 

 on the eastern slope of the mountains. 



Eegarding 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
