XVIII. — On a new Species of Gulraca. 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. H. 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 culmen ; the lower belly is greyish blue ; under 
tail* coverts blue, like the breast. 
Guiraca Foihschildii ) sp. n. 
Bill similar to Guiraca cyanoides y straight, acute ; culmen 
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 cheek brighter 
and more extended ; upper and lower parts darker blue than 
in the old form ; rump uniform with the mantle; belly nearly 
black ; 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
