base is partiully coveied wiih small thick- s€t, shoit, setaceous 

 feathers ; between the eye and base of the bill are a few weak 

 and short hairs ; the upper part of the head, as far as the nape, 

 is capped by deep-black, having a blueish gloss : between the 

 nostrils and the eye, as well as on the chin and throat, the colour 

 is -white, which changes to a pale cinereous grey on the sides of 

 the head and round the neck ; the ears at their base and margin 

 of the eye tinged with yellow ; the rest of the upper plumage 

 yellowish-olive. The under plumage on the lower plrt of the 

 neck and breast, the sides, and the inner wing-covers are clear 

 yellow, and from that to the vent white. Wings two inches long, 

 the quills brown, margined externally with olive and internally 

 with yellow ; the first and second quill progressively shorter than 

 the third and fourth, which are of equal length. Tail short, 

 slightly divaricated ; olive, with whitish marginal tips. Legs 

 blueish-black ; the three fore-toes are equally cleft, but a mem- 

 brane will be found connecting them ctpuilly at the base nearly 

 as far as the first joint. 



Temminck must" be mistaken in giving as a generic character 

 to this genus, that the external toe is connected to the middle 

 one as far as the first joint, and the inner toe cleft to the base; 

 at least such is not the case either in my specimens of this bird 

 or in those of the Cayenne Shrike : and they have been care- 

 fiilly relaxed in warm water, the best method of ascertaining 

 such peculiarities.
