314 Mr. O. Salvin's Visit to the 



In their note on the so-called Lampornis mango (ii. p. 440), 

 Mr. Elliotts 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. Ridgway (/. 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. trichopsis, Wagler, 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 

 we 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. 

 Ridgway 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 '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. 376).
