tiuctly tipped with dull bluish ; under surface of reniiges decidedly paler 

 bluish green, the secondaries aiul approximate primaries edged with 

 pale yellow. Bill wholly whitish. Length (skin) 4.80, wing 3.30, tail 

 1.85, culinen .50, gonys .33, widtli of upper mandible at base .35, tarsus 

 .45, inner toe .50. 



Adult female (in Coll. Am. JMus. Nat. Hist. New York 5 Cartagena, 

 Colombia 5 C. Wood) : Lower back and rump vivid I*aris-greeu, greater 

 wing-coverts light grass-green, edged with light Paris-green, primary 

 coverts and secondaries deep grass-green, edged with paler; forehead 

 gamboge-yellow, and under wing-coverts, with axillars, entirely light 

 Paris-green. Otherwise much like the male. Length (skin) about 5; 

 wing 3.20, tail 1.95, culmen .45, gonys .30, width of upper mandible at 

 base .32, tarsus .40, inner toe .48. 



The female of this exquisite species resembles much more closely 

 that of the Lower Amazonian P. deliciosa than that of P. guianensis, 

 the dillerences being very slight, and consisting chiefly in the larger 

 size and deeper, as well as inore extensive, yellow of the forehead ; with 

 only one specimen, however, I cannot say that these differences arc con- 

 stant.

Sp. CHAR. — Adult male: Plain green above, the hind neck duller 

 and tinged with grayish, the lower back and rump rich emerald-green, 

 or Paris-green ; forehead and sides of head similar to rump, but less 

 vivid; lower parts paler green than upper; greater wing-coverts light 



"Psittacus cyanopterus Bodd. (Tal)l. P. E., 1783, 27), based on the Petit Pcruche, 

 du Cap de Bonne- Esperance, Pi. EuL, 455, fig. 1, is not, with our present knowledge, 

 (Icteruiinable. There is no more reason for identifying it with the present species 

 than -with any other, especially since there is so much uucertaintj^ regarding the 

 habitat, which was given by Buffon as the Cape of Good Hope. P. mj?c/ms Mull. 

 (S. N. Siippl. 1767, 80), and ofGMEL. (S. N., i, 1788, 3-50) has precisely the same basis. 

 A (japornis guianensis Swains., is unquestionably the present bird, as is also Psiltacula 

 riridissima Lafk., though tlie latter may possibly prove to be a local race. (See spe- 

 cial remarks upon the type, on p. 544.) 



t Svvainson's description is as follows: "Green; spurious quills and inner wing- 

 covers amethystine blue; outer margin of the shoulders light green ; greater wing- 

 covers tinged with bluish. Female entirely green. (P. cajyensis, Auct., PI. Enl., 455, 

 fig. 1.) The smallest parrot of Demerara, where it is found iu largo flocks, size of 

 the last."
