specimen of this species^ which appears to us to be nothing more 

 than Z. pileata in immature plumage. At the same time it is 

 very possible that the two birds may be distinguishable in their 

 adult dress, although we have never been fortunate enough to 

 meet with specimens of Z. canicapilla. Mr. Darwin, in his 

 notes on the zoology of tbe voyage of the ' Beagle', evidently 

 recognizes them as distinct.

Since we wrote our former article, we have taken Dr. 

 Cunningham's example to Paris and compared it with the 

 typical specimen of P. gayi in the Jardin des Plantes. It turns 

 out, as we had anticipated, that the smaller species, Fringilla 

 formosa of Gould, is the true F. gayi, and that these two names 

 must henceforth be regarded as synonymous. Of the larger 

 species (with which Dr. Cunningham's skin perfectly agrees) there 

 are also two skins in the Paris Museum, marked " Chili, Gay." 

 "We have therefore little doubt that this is the Chlorospiza 

 aldunatii of Gay (Faun. Chil. Zool. p. 356), although it does 

 not quite correspond with the description there given. We 

 may remark that Gay correctly quotes Fringilla formosa, Gould, 

 as a synonym of his Chlorospiza gayi. 



If this view be correct, the synonyms of these two allies will 

 stand as follows : —
