CHATTERER. 181 



8.— WHITE CHATTERER. 



LENGTH one foot. Bill and legs black ; chin, throat, as far as 

 the breast, and round the eye, bare; plumage entirely white; at the 

 bend of the wing a small, bare, callous, space, but not amounting 

 to a knob, or spur ; the first quill of the wing shortest, increasing to 

 the third, which is the longest ; tail four inches long. 



I have seen two specimens of this bird, which probably belong 

 to the Carunculated Species, but without any trace of the fleshy 

 caruncle, which hangs so conspicuously over the forehead of that 

 bird, in both sexes. 



9.— BLACK-HEADED CHATTERER. 



Procnias melanocephalus, Maxim. Trav. i. p. 143. 

 Averano, Tern. Man. Ed. ii. Anal. p. lxiii. 



LENGTH eight inches, seven lines. Head black ; irides cinnabar 

 red ; the upper parts of the body Linnet-green, the lower yellowish 

 green, with darker transverse stripes. 



Inhabits Brazil, about the neighbourhood of St. Salvador, and 

 thought to be a new species. 



10— AZURE CHATTERER. 



Procnias cyanotropus, Maxim. Trav. i. 160. Tern. Man. Ed. ii. Anal. p. lxiv. 



THIS is an extremely beautiful species ; if held against the light 

 the whole bird appears of a splendid azure, and turned from the 

 light, it shews a shining bright green; wings and throat black; the 

 under part of the body white. 



Inhabits Brazil : in the Berlin Museum it is named Procnias 

 ventralis.
