500 COEVIDJi. 



This species is restricted to Southern Mexico and Guatemala. Sumichrast says that 

 it is found in the temperate region of Vera Cruz, where it prefers the pine-woods 

 rather than the denser forests that cover the more elevated portions of that region ; it 

 occurs also in the State of Puebla. In Guatemala, so far as we know, it only occurs in 

 Alta Vera Paz, in the neighbourhood of Coban, and the country lying in the direction 

 of Cahabon. It is one of the birds frequently met with in collections from that district. 

 In the original catalogue of the birds of Guatemala it is stated to occur in Honduras ^, 

 but. on what authority we are now unable to say. The bird found in Costa Rica, as 

 will be seen below, is slightly different.

We have long possessed specimens of this bird both from Costa Eica and from the State 

 of Panama, but we hesitated to describe this southern form of G. ornata as a distinct 

 species, the differential characters being so slight, and Mr. Sharpe treated them in the 

 same way. Mr. Eidgway, however, has recently separated the Costa-Eican bird as 

 C. cucullatus'^, giving characters which we are able to recognize; we therefore employ 

 his name. The first Costa-Eican specimen that came under our notice was obtained by 

 Carmiol in 1869, and this bird was referred to Cyanocitta ornata ^ ; our examples from 

 the State of Panama were acquired at a later date. The examples described by 

 Mr. Eidgway were collected in Costa Eica by J. Cooper, and were obtained on the 

 Atlantic slope of the mountains — at Eio Sucio at an altitude of 800 feet above the sea, 

 and at Navarro, at an altitude of 3500 feet. The specimens from the State of Panama 

 were doubtless obtained from the western or Pacific side.
