GUIRACA C^RULEA CHIAPENSIS (Nelson). 

 CHIAPAS BLUE GROSBEAK. 



Adult male unknown. Adult female precisely similar to that of 

 G. c. lazula in coloration, but decidedly larger, with the bill relatively 

 larger; length (skins), 158.75-176.53 (167.6-1); wing, 88.*J0-90.93 

 (89.92); tail, 71.12; exposed culnien, 17.78-20.07 (18.9:3); depth of bill 

 at base, 15.24-15.75 (15.49); tarsus, 21.59-23.11 (22.35); middle toe, 

 17.53-17.78 (17.66).' 



'Either Goniaphea or Guiraca may have been meant; dou))tless the former, since 

 that generic name was used by him as late as 1874 (Birds of the North-West). 



* Two specimens. The second is from the State of Oaxaca, but the exact locality 

 unknown. It is not typical of this form, but agrees better with the type in size of 

 bill than with any specimen in a large series of G. c. lazula, as the following will 

 show:
