Mr. O. Salvin's Visit to the 
In their note on the so-called Lampornis mango (ii. p. 440), 
Mr. Elliot's paper “on the Humming-Birds of the West 
Indies " (Ibis, 1872, p. 350) is overlooked. It is there shown 
that the Jamaican bird is the true Lampornis mango of Lin¬ 
naeus, and that the bird commonly and here so called must 
bear the name L. violicauda (Bodd.). 
Buteo harlani (iii. p. 292). At Mr. Eidgway's request I 
have, since my return to England, examined the specimen in 
the British Museum, said to be Audubon's type of this species, 
and find that it agrees closely with the specimen he showed me 
in Washington. Now that it is shown that neither the dark 
melanitic forms of Buteo borealis nor those of Buteo swainsoni 
are referable to Buteo harlani , I think the species must be 
acknowledged distinct—a conclusion arrived at separately by 
both Mr. Eidgway {l. c.) and Mr. Sharpe (Cat. Birds, i. p. 191). 
Mr. Sharpe includes Guatemala in the range of this species; 
but this requires confirmation, as the bird so called (Ibis, 1859, 
p. 217) in our Guatemalan lists is B. borealis. The young bird 
Mr. Sharpe describes from Mexico belongs to Tachytriorchis 
albicaudatus , as he and I have since determined. 
In a paragraph attached to Scops asio , var. maccalli (iii. 
p. 53), I was somewhat surprised to see our assignment of 
the name S. trichop sis, W agler, totally dissented from. On 
examining the specimens so called in the Smithsonian Insti¬ 
tution, I found that they really belong to the bird to which 
/W wo apply the name Scops brasilianus (Gm.), and have little 
to do with Wagler's bird. The toes of S. brasilianus are nude. 
Wagler adds to his description of his trichopsis “digiti setis 
singulis sordide albis tecti," at once showing that the species 
must be considered allied to S. asio and S. macalli, and that Mr. 
Eidgway could not have verified the names wrongly attached 
to the specimens of S. brasilianus by studying Wagler's origi¬ 
nal description. Another race or variety of S. asio is described 
in the f North-American Birds' as Scops enano. It only remains 
to be seen which of the birds, S. maccalli or S. enano, has to 
take Wagler's name S. trichopsis. A specimen in the British 
Museum, from Mexico, which belongs, no doubt, to S. mac¬ 
calli, agrees best with Wagler's description (Isis, 1832, p.276).
