XVIII. — On a new Species o/'Guiraca. By Edward 

 Bartlett, Curator of the Maidstone Museum. 



While closely comparing my specimens of this genus I 

 observed a great difference in the bills and in the general 

 colour of the birds obtained by Mr. II. Whitely on the 

 Carimang River, British Guiana, which I think are sufficient 

 to separate them from the well-known Guiraca cyanea, auct. 

 The bill of Guiraca cyanea is short, robust, and much 

 curved on the culmcn ; the lower belly is greyish blue ; under 

 tail- coverts blue, like the breast. 



Guiraca Bothscliildii, sp. n. 



Bill similar to Guiraca cyanoides^ straight, acute ; culmeu 

 not curved as in Guiraca cyanea, length of culmen 0*75. 



Male. — General colour similar to Guiraca cyanea, the 

 silvery blue of forehead and spot of same on check brighter 

 and more extended; upper and lower parts darker blue than 

 in the old form ; rump uniform with the mantle ; belly nearly 

 black J under tail-coverts blackish, faintly tinged with dark 

 blue. 



Female. — Dark umber-brown, palest on the forehead and 

 chin. Much darker than the female of Guiraca cyanea. 



This well-marked species by its size, colour, and straight 

 culmen cannot be confused with either Guiraca cyanea or
