PSITTACULA. 581 



tail is short and but slightly cuneate, the rectrices pointed ; there is a tufted oil-gland, 

 but no furcula (Salvadori). 



The ten or twelve species composing the genus are distributed over nearly the whole 

 of continental Tropical America from Western Mexico to Brazil and Bolivia. Only 

 one species is found within our region, and this is peculiar to the Tres Marias Islands 

 off the coast of Western Mexico, and the mainland opposite from Sonora to Manzanilla. 

 The next species in point of distance is found in Colombia, leaving a wide hiatus in 

 the range of the genus unoccupied by any species of Psittacula.

The types of this species, from the Massena collection, are in the British Museum ^. 

 They are marked as from Bolivia, but no doubt wrongly. They are quite as dark as 

 the birds, from the Tres Marias Islands which Mr. Eidgway separated as F insularis ^^. 

 Mr. Brewster subsequently described a pale form from Sonora as P. cyanopygia pallida i^. 

 Col. Grayson noticed that the island bird differed somewhat from that of the mainland. 

 Lawrence placed them together in 1874 ^, but Mr. Ridgway separated them in 1889 ^o. 

 Count Salvadori again, in 1891, united all three forms under the oldest title 6, and we 

 follow him in so doing. The island birds are a little darker, but the difference is very 

 slight. Two Sonora specimens from the same place as Mr. Brewster's types of P. c. 

 pallida are in rather abraded plumage, but are so close to the typical birds that we 

 see no grounds for separating them. It may be remarked that the materials for a 

 satisfactory comparison of the supposed races of this Parrot do not exist in any one 

 museum, so that there may be more difference between them than appears from the 

 ten specimens before us. The only fully adult male specimen we have seen is the type 

 of that sex.
