42 PATAGONIAN EXPEDITIONS : ZOOLOGY. 



The female is noticeably darker both above, below and on the head, 

 which lacks the gray crown and occiput of the male. "Bill black; part 

 of a red flesh-colour" (Burmeister). 



A young male, 7,923 Princeton University Collection, taken at Rio 

 Chico, Patagonia, 12 March, 1898, is in the first plumage. This bird is 

 grayer below and darker above than are adults and the vinous dove color 

 of more advanced age is lacking. The feathers on the breast and neck 

 are tipped narrowly with light cinnamon giving a slightly scaled ap- 

 pearance. The upper coverts of the wings are tipped in a like manner. 

 There is a decided whitish area in front of each eye. The feathers of the 

 crown are tipped with bright rufous. This color is also conspicuous on the 

 shoulders, and while the dark spots of the inner upper wing coverts, 

 scapulars and tertials are apparent, they are not well defined and all of 

 these feathers are strongly marked with bright rufous in an irregular way. 

 The edging of the wing quills is rufous or deep buff. The tail is like that 

 of the adult. The blackish blue spots back of the eye and below in ear 

 are not apparent. There are no iridescent areas on the neck. The bird 

 is full grown. 



An older bird, also a young male, 8,302 Princeton University collection, 

 taken at Santa Cruz, Patagonia, 15 February, 1898, is much like an 

 adult, but many feathers on the breast, back and shoulders have median 

 silvery white triangular markings. The throat and forehead in this bird 

 are whitish and a few feathers on the crown have the same median mark- 

 ings already referred to. The blackish blue spots, behind the eye and 

 below the ear are indicated but are not so conspicuous as in the adult. 

 The iridescent areas of the neck are faintly indicated. 



Geographical Range. — South America. From Ecuador southward on 

 the west, and on the east from Fernando de Noronha to Brazil, the 

 Argentine Republic and Patagonia, probably to the Straits of Magellan. 



The collections made by Mr. J. B. Hatcher for Princeton University 

 include five of these birds, but there is no adult male bird represented. 

 The description of the adult male is based upon material in the British 

 Museum of Natural History, and that from the Museo de La Plata, and S. 

 Pozzi collections in the Princeton University Museum. Mr. Hatcher in 

 his MSS. notes says of this dove "common along valleys where there is
