I confess I should rather have supposed the black-throated 

 bird of this singular pair (represented in the upper figure in PI. I.) 

 to be the male ; but Mr. Lawrence, in answer to inquiries on this 

 point, assures me that his description of the sexes (which I have 

 here followed) is correct. Mr. Lawrence says, in a letter dated 

 " New York, August 1 1th, 1861" :— 



" Since my description of this species, I have received from 

 Messrs. J. M'^Leannan and J. R. Galbraith a fine collection of 

 birds, made for me during the past winter on the Isthmus of 

 Panama, with such observations as they were able to make. One 

 male and two females were the only specimens that were pro- 

 cured of this species, and the following short note the only in- 

 formation that is given of it : — 



"*Irides brown. Not often met with. Found on high trees. 

 Length 7 inches.' " 



Mr. Lawrence adds (Nov. 7th) ; — " The sexes of the Capita are, 

 without doubt, correctly given. I have seen Mr. Galbraith in 

 reference to this point. He states that his determination of 

 the sexes was made in all cases by dissection ; that he particu- 

 larly remembers this species, and is positive as to his specimens 

 being correctly marked." 



I may add to my remarks on Tetragonojjs ram2)hastinus 

 (' Ibis,' 1861, p. 184, pl.vi.), that the British Museum now con- 

 tains an example of this singular bird, lately received from 

 Ecuador through Mr. Gould. In this specimen the nuchal 

 feathers are rather elongated, and form a sort of tuft, which I 

 have not noticed in the two examples in Sir William Jardine's 

 collection.
