Variation in both sexes is excessive, apparently exceeding the dif- 

 ference on which the Central American form, C. albilinca crissalis, is 

 based. Thus, two males are deep purplish vinaceous below, with the 

 under tail-coverts strongly washed with the same color, while other 

 specimens are of a decidedly more plumbeous cast, with the under tail- 

 coverts gray. Indeed, these latter birds are not certainly distinguish- 

 able from the single adult male crissalis with which they have been 

 compared. Females vary in the same way, but average darker than 

 four female crissalis. 



This fine pigeon ranges in this region through the Subtropical and 

 for a distance into the Temperate Zone, or from 5,000 up to io.oco feet, 

 wherever forest or scrubby woodland is found. It is fairly common 

 at all such points in its habitat, but is very shy and must be shot at 

 long range as a rule. A nest was found on the San Lorenzo, at about 

 7,500 feet altitude. It was a frail, flat structure, placed in a small tree 

 about ten feet from the ground, and contained two creamy white 

 eggs. 



Family PSITTACID/E. Parrots. 



123. Amazona ochrocephala panamensis (Cabanis). 



Amazona ochrocephala panamensis Ridgway, Bull. U. S. Nat. Mus., No. 50, 

 VII, 1916, 249 (Fundacion). 



Five specimens : Fundacion. 



Easily distinguished from A. 0. ochrocephala by its smaller size and 

 paler yellow crown, with the forehead also yellow, not green. One 

 specimen shows numerous parti-colored dull red and yellow feathers 

 on the throat. 



The local range of this parrot is almost the. same as that of A. aina- 

 zonica amazoiiica, than which, however, it is less common. It has 

 been detected also in the Rio Cesar Valley at Valencia, and even as 

 far east as Fonseca, along the river. 



124. Amazona mercenaria (Tschudi).

 (Bangs' reference). 



Eleven specimens : Cerro de Caracas and Paramo de Mamarongo. 

 Judging from Tschudi's description and plate, these may belong to 

 a separable form, for which the name canipalliata of Cabanis would be
