186 Messrs. Sclater and Salviu on the Birds collected 



only, so far as we know at present, are peculiar to Patagonia ; 

 two others [Phrygilus melanoderus and P. xanthogrammus) are 

 only found in Patagonia and the Falkland Islands. The re- 

 maining twenty- four are all met with in Chili, while only eight 

 out of these occur in the Ai'gentine Republic, and these eight 

 are species likewise found in Chili. It would seem therefore 

 that, so far as we can judge by the character of the Passerine avi- 

 fauna, Patagonia belongs strictly to the same zoological province of 

 the Neotropical Region as Chili, and has probably received its 

 bird-population from that country. 



Having said thus much upon the general /oaes of the Pata- 

 gonian avifauna, we return to Dr. Cunningham^s collection. 

 Nearly the whole of the species it contains are such as have been 

 already obtained in the same locality by Capt. King and Mr. 

 Darwin. 



1. TuEDus FALKLANDicus, Quoy & Gaim. 

 One specimen in nestling plumage. Sandy Point, Dec. 26th. 

 " Iris blue." 



-|-- 2. Phrygilus gayi. Fringilla gayi, Gould, Zool. Voy. 

 ' Beagle,' iii. p. 93. 



One skin. Gregory Bay, May 1st. This skin agrees with those 

 determined as P. gayi in the 'Zoology of the ' Beagle \' But 

 we suspect there has been some error here, and that the allied 

 but smaller species, described by Mr. Gould as Fringilla formosa 

 {lac. supr. cit.), is the true F. gayi of Eydoux and Gervais. To 

 ascertain this point without doubt, it will be necessary to con- 

 sult the typical specimens in the Paris Museum, which we have 

 not yet had an opportunity of doing. 



3. Chrysomitris barbata (MoL). 



Gregory Bay, May 19th. Two skins in immature plumage. 



4. Sturnella militaris (Linn.) ; Cunningham, antea, p. 126. 

 One example, from near Cape Possession, Jan. 1867.
