pagus hidentatus. In the Norwich Museum are specimens of A. 

 pileatus irom. Brazil; Ecuador, Pallatanga (Fraser') ; Chih, and Straits 

 of Magellan, — and of A. cooperi from California, Monterey ; Texas 

 and Mexico, Orizava. The adult specimens of the present bird 

 from Oaxaca show a whole-coloured hood nearly as dark as in A. 

 pileatus, which younger specimens never do, whereas, as stated above, 

 A. pileatus does so in all ages." — J. H. G. in epist.

In spite of the number of new species that have lately been de- 

 scribed among the Pigeons, this bird appears to have remained un- 

 noticed. There is no specimen of it in the British Museum ; and it 

 is not included in Bonaparte's ' Conspectus,' which contains such an 

 elaborate account of the family. I therefore consider it to be pro- 

 bably new. Its nearest allies are Columba fiavirostris, v/hxch has 

 the bill yellow, and C. rvfina, which has a cinnamomeous-brown tail.
