This species is very distinct, on account of the fine cinereous 

 colour of its upper parts, from all hitherto described species, 

 as enumerated by Coues in his Monograph. The only species 

 with which it might perhaps be identical is Puffinus mundus 

 Kuhl {Nectris munda, Banks, tab. 24) ; but the only description 

 we have been able to consult, that of Bonaparte (Consp. Av. ii. 

 p. 205), is far too brief and incomplete to be recognizable. The 

 following is his diagnosis : — " Magnitudine Perdicis, alis cauda 

 aliquantum brevioribus ; cauda brevi, cuneiformi : rostro cyaneo- 

 griseo, apice nigro : pedibus cyaneis, unguibus falculatis.^' 



It is true that the above description fits our specimen in some 

 parts, but certainly not in the shape of the tail, which is not 

 wedge-shaped, but rounded; besides, the bill has also a black 

 culmen, and the feet are not entirely blue; and then not a word 

 is added about the coloration, so characteristic in this species — 

 fine cinereous lead-colour above, and pure white below. 



The only way to decide this interesting question is to com- 

 pare our description with Banks^s figure of his Nectris munda ; 

 it appears also that since his time no one has observed specimens
