was still imperfect, and only laid claim to be an outline, 

 the details of which I trusted would shortly be filled up by 

 some competent observer. 



But alread}^, in a recent review of my 'Ibis' article, 

 lately published in a scientific periodical at Lisbon,"^ Pro- 

 fessor Barbosa du Bocage has been so good as to add a 

 very valuable supplement, of which I shall largely avail 

 myself, and which will extend our acquaintance with 

 Portuguese birds to every species hitherto certified to have 

 occurred in that country. The Professor, in the true spirit 

 of a naturalist, has exerted himself to render my list more 

 complete and valuable, and, with that view, has confined 

 himself to the system I had adopted, by adding those 

 species only of whose existence, within the limits of 

 Portugal, he holds incontrovertible proofs, and of which 

 authentic examples now actually exist in the Museum of 

 Lisbon. 



On examining this appendix, which contains forty-two 

 species, and on comparing it with my previous list, it 

 appears that of the fifty-seven species w^hich I had already 

 incidentally mentioned, as confidently asserted to be found 

 in Portugal, but of whose appearance there I had no 

 personal evidence, no less than thirty-six have now been 

 identified, while only six species, of which I had heard no 

 previous tidings, must be added to my total amount. 



We have now then, to our former catalogTie of 193 veri- 

 fied Portuguese species, to add a supplementary list of 

 forty-two, no less carefully determined, which swells the 

 total to 235 ; and if w^e reckon those of whose appearance 

 in Portugal we have been assured, though hitherto they 

 have not been positively identified, we arrive at a grand 

 total of 256 species, which, though by no means professing
