Five skins. 



This jay was described from specimens which were supposed to have 

 come from Talamanca, but if they really did, it must have been from high 

 up in the mountains of the interior, and not from the region generally 

 meant by Talamanca. Farther to the north I secured four specimens of 

 the species at La Hcr.dura, high up in the upper part of the Rio Sucio 

 valley, at an altitude of about 4,000 feet, and later a single bird on the 

 Volcan de Turrialba at about 8,000 feet. All were shot in the heavy forest, 

 rather high up in the trees, and did not appear to be very shy. I did not 

 hear their note. 



I should say that the species was confined to the higher portions of 

 nearly the whole of the country, above 4,000 feet. It is not a common 

 bird, however, and not many have been secured by collectors.

C. H. Lankester Collection: Banana River. 



Carnegie Museum: Cuabre de Talamanca (Carriker). Five specimens. 

 This handsome jay is confined to the southeastern portion of Costa 

 Rica, from the Banana River southward, from sea-level up to not more 

 than 800 feet. I found it fairly common along the Sicsola River in the 

 vicinity of Cuabre, but always in small flocks and very shy and hard to 

 approach. Their note resembles a little that of Psilorhinus, but they are 

 not noisy birds by any means, only uttering a few notes when disturbed,
