instead of white and sides and flanks deep buff washed with olive, instead 

 of light buffy olive), brown postocular streak much narrower, sides of

Cyanocorax affinis zeledoni. Talamanca Jay. 



Similar to C. affinis Pelzeln, of Colombia, but decidedly brighter col- 

 ored, with under parts of the body and tips of rectrices distinctly vellow 

 (light creamy yellow) instead of white or yellowish white. 



Isthmus of Panama to Costa Rica ( Talamanca).

 C. Zeledon. 



Those who have recognized two geographical forms of this 

 species have restricted the name affinis to this form and called the 

 Colombian bird Cyanocorax sdateri Heine. The type of C. affinis, 

 however, came from Bogota, and the original description gives the 

 color of the underparts, etc., white. Furthermore, having com- 

 pared birds from Bogota and Cartagena (the type locality of 

 C. sdateri), I can discover.no difference between them. 



Cyanolyca mitrata. 



This name is proposed as a substitute for C. ornata {Pica 

 ornata Lesson, 1839), the latter name being preoccupied by Pica 

 ornata Wagler, 1829, for a species of the Asiatic genus Cissa. 



Perisoreus obscurus griseus. Gray Jay. 



Similar to P. obscurus but decidedly larger (except feet) and coloration 

 much grayer ; back, etc., deep mouse gray, instead of brown, remiges and 

 rectrices between gray (No. 6) and smoke gray, instead of drab gray, and 

 underparts grayish white instead of brownish white. 



British Columbia, Washington, Oregon, and northern California, east 

 of the Coast and Cascade ranges.
