to^^■arcls P. lonyirostris, having a small buff spot at the base 

 of the white tips to the outer rectrices. It is therefore 

 possible that future researches may degrade P. mexicanus to 

 subspecific rank, but it certainly cannot be confounded with 

 P. longirostris. Boucard, Humm. J3. 1892, p. 83, and Gen. 

 Humm. B. p. 377, described as a new species P. panamensis 

 from Panama and Veragua; but his types are the same as 

 P. cassini, Lawr., a form which seems slightly richer in 

 colour than typical P. lungirostris from Guatemala, which, 

 howevei', in my opinion, cannot be separated without much 

 further evidence. 



In 1894, in Nov. Zool. i, p. 57, I mentioned a bird shot 

 by Mr. O. T. Baron at Naranjal, near the Rio Pescado, in 

 Western Ecuador, as doubtfully belonging to Phaethornis 

 superciliosus (L.), and promised to " speak of this bird 

 again." The time for this has now come, since I have been 

 able to examine three more specimens of this bird — one 

 more from Naranjal, one from Western Ecuador, bought as 

 P. superciliosus from H. Whitely, and one from Esmeraldas, 

 West Ecuador, formerly in Mr. Sclater^s collection, now in 

 the British Museum. Tliis last bird is the one mentioned 

 by Sclater in P. Z. S. 1860, p. 296, as Phaethornis moorii, 

 while in the Cat. B. xvi. p. 273 it is enumerated as specimen 

 /' of P. longirosti'is. It is certainly neither of the two, but 

 a distinct new species, which I wish to name 



+. Phaethornis baroni, sp. nov., 



in honour of Mr, Baron, who already in 1893 suggested to 

 me that it was a new species, but I did not see sufficient 

 evidence of it then. P. baroni difi'ers from P. longirostris 

 in having the tips of the outer rectrices bordered with pure 

 white. Mr. Salvin, who does not separate the large Mexican 

 form with the white-tipped outer rectrices, says that southern 

 examples have these tips buff ; but certainly the West- 

 Ecuadorian birds are the southernmost ones, and yet they 

 have these tips snow-white. Besides the different colour of 

 the tips of the outer rectrices, the wings and tail of P. baroni 

 are much shorter, the abdomen is paler and not so buff, the
