r)4l KEVIKW OF GKNITS P8ITTACULA. 



j::^];iucous-greeti, or pale greeuish blue ; innermost primary -coverts, dark 

 hyaeintU-blue ; remiges entirely green ; under wing-coverts and axillars 

 cliieHy light bluish green, the tips of the longer axillars and a patch on 

 l>osterior portion of lesser-covert region dark hyacinth-blue. 



Adult female : Above light i^arrot-green or bict'-green, becoming 

 yellow on forehead and bright yellowish green on lower back, rump, 

 and upper tail-coverts; sides of head and lower parts apple green ; no 

 blue whatever on wing. 



Au adult male from Venezuela (No. 70090) measures as follows: 

 Wing 3.35, tail 1.90, culmeu .48, width of upper mandible at base .35; 

 tarsus, 45, outer toe .50. 



Au adult male from tlie Essequibo Eiver, Guiana, in the collection of 

 the American Museum of Natural History is similar to the preceding in 

 plumage and measures as follows: Wing 3.25, tail 1.75, culmen .48, 

 width of upper mandible at base .32, tarsv.s .40, outer toe .50. 



The type of P. viridisslma Lafr. (No. 93, Lafresuaye Collection, Bos- 

 ton Society Natural History), from Caracas, agrees in all essential re 

 spects with an adult male from Venezuela in the National Museum col- 

 lection (No. 70990), except that there is d\;cldedly less yellow in the 

 green, the lower parts being a clear Paris-green, the forehead and sides 

 of head similar but brighter. The upper parts are a darker and purer 

 green (almost grass-green), much duller and grayer on hind-neck, the 

 lower back and rump vivid emerald-green, the upper tail-coverts more 

 yellowish. Wings exactly as in No. 70990, except that the general 

 green color is darker and purer. Length (mounted specimen) 4.80, 

 wing 3.25, tail 1.90, culmen .50. 



Two adult females, unquestionably of this species, have been ex- 

 amined, one (belonging to the American Museum of Natural History) 

 from British Guiana, the other, one of the types of P. viridissima Lafr., 

 said to be from Caracas. These two are quite identical in coloration, 

 and measure as follows : Wing 3-3.20, tail 1.80, culmen .4S-.50. They 

 may readily be distinguished from females of P. passerina by the much 

 lighter and more yellowish green coloration of the rump and up[)er 

 tail-coverts, distinctly yellow frontlet, less yellowish cheeks, and smaller 

 size. 



Another specimen, said to have come from Sta. Marta (possibly not 

 in Colombia, however), belonging to the American Museum of Natural 

 History (Lawrence collection), is also without much doubt this species, 

 since it agrees with the two females mentioned above in all characters 

 which distinguish them from the female of the Colombian P. cxquisita, 

 viz, decidedly less yellowish tone of the coloration both above and 

 below, much less extent of the yellow on the forehead, and darker and 

 more uniform green of the greater wing-coverts. Compared with the 

 Guiana specimen it has the yellow frontal band (about .10 of an inch 

 Avide at base of culmen, but extending laterally quite to the eyes) of a 

 purer yellow, and rather abruptly defined against the green ; the greater
