 Thahirania furcatoideSy Gould, in text to T.fwcata. 

 Habitat. Para and the lower part of the Amazon. 



This bird is very Hke T.furcata, but is of smaller size, has a much less-forked tail, and the bi'east ultramarine- 

 blue instead of purplish-blue. I have at this moment seven specimens before me, all of which are alike, and readily 

 distinguishable from the Cayenne bird.

Thalurania forficata^ Cab. et Hem. Mus. Hein. Theil iii. p. 24. 



Habitat. Supposed to be the neighbourhood of Para. 



Through the kindness of Dr. Peters, the Director of the Royal Museum of Berlin, I have had their specimen of 

 T, forficata sent to me for comparison. It is certainly distinct from any of the species contained in the collections 

 of this country : in size it is nearly the same as T.furcata ; but its bill is rather shorter, its tail longer, more deeply 

 forked, and of a purplish-black colour instead of steely-black : it differs from that bird also in having the blue 

 colouring more extended down the back, approaching to that of T, Watertoni ; the green of the throat is circum- 

 scribed and truncate below, as in T. furcata ; and the crown of the head is black, but near the centre is a single 

 small blue feather : I think it likely that this is accidental, as the bird appears to be fully adult : the under tail- 

 coverts are black.

Habitat. The Andes of Quindios. 



I have a specimen of this bird, collected by Warszewicz on the Cordillera of Quindios, which is precisely the 

 same as the type specimen of the T. Fannyi of MM. Bourcier and Delattre. It differs from my T. verticeps in beino- 

 considerably smaller and in having the abdomen purple-blue in lieu of cold prussian-blue.
