FRINGILLA TEMPORALIS et BICHENOVII. 



We would adopt Mr Swainson's genus Estrilda for these species, and 

 some others of like form. The following characters and observations are 

 given by that ornithologist in the 11th Number of the Zoological Journal: 



ESTRILDA, Swain. 



Rostrum breve, conicum, immarginatum ; alas breves, rotundatae; remige, l mo . spurio, mi- 

 ll uto, 3ti°, 4 to , 5to, aequalibus, longissimis ; cauda subelongata, gradata. 



Type Loxia estrilda, Linn. 



* We are indebted to the kindness of Mr Swainson for the loan of this beautiful little Psaris : it ap- 

 proaches near to the characters given to the Lanius inquisitor of Olfers, quoted in Griffith's edi- 

 tion of the Regne Animal of Baron Cuvier, — a species, however, which cannot be determined from this 

 notice, applicable as it is to three others. Mr Swainson has placed it provisionally in his manuscript notes 

 under the above title; and we take this opportunity of expressing our acknowledgments for the individual de- 

 dications he has made to us in the species of this group. 



f We are aware of another species, but which we have at present no means of characterizing. It is 

 about the size of Ps. cristatus. The cheeks clothed, having the intermediate falciform quill very long ; the 

 colour entirely black- 



X We trust that Mr Swainson will accept the above dedication as a small tribute to the friendship 

 we feel for him. It is a species, also, which we know was met with, if not first discovered by himself, in the 

 virgin forests of Brazil, where he informs us it is particularly rare.
