XANTHOURA LUXUOSA GUATIMALENSIS (Bonaparte). 

 GUATEMALAN GREEN JAY. 



Similar to X. I. vivida, but under parts of body entirely j^ellow or 

 but slightly tinged with green, and green of upper parts duller, 



Adu/f male.— Length (skin.s). 264-284.5 (276); wing. 110-118 (114); 

 tail, 132-139 (135); exposed culmen, 25-28 {2Q); depth of bill at nostril, 

 10.5-12 (11); tarsus, 35-40 (37); middle toe, 18-21.5 (19.5).« 



Adidt female.— Ijength (skins), 244-272 (257); wing, 107-109 (108); 

 tail, 119-126 (122.5); exposed culmen, 24-25 (24.5) depth of bill at base, 

 10-10.7 (10.2); tarsus, 34-36 (35); middle toe, 18.5-20.5 (19.5).^ 



Yucatan; Campeche; eastern and central Guatemala; British Hondu- 

 ras; northern Honduras (San Pedro, Santa Ana, Omoa, Chamelicon, 

 etc.) 



intermediate, are rather nearer to this form than to A'. I. speciosa, the Jaliscan sub- 

 species. Two fine specimens from Nenton, northwestern Guatemala, although 

 appreciably more yellow below, are clearly referable to this type and not to the 

 bird of central and eastern Guatemala (A'. I. guatimalensis). It may therefore be 

 considered as reasonably certain that the range of the present subspecies includes all 

 of the Mexican States named above. 



« Eight specimens; five from Yucatan, three from Honduras. 



& Three specimens, from Yucatan. 



Yucatan and Honduras specimens, respectively, average as -follows: 



Specimens from central Guatemala (Choctum, Vera Paz, Coban to Clusec, etc.) 

 are less purely yellow Iteneath than those from Yucatan and Honduras, some speci- 

 mens being quite strongly tinged with green. The three specimens from Chameli- 

 con, Honduras, and those from Yucatan are wholly pure yellow (intermediate 

 between naples yellow and canary yellow) below, a few only of those from the 

 last-named country being very slightly washed with green on sides.
