106 SPECTACLE, OR WHITE-WINGED WATER-CHAT. 



nor has the female, until now, ever heen described 

 Sonnini, indeed, in his translation of Azara, sup- 

 poses that this is the Bee argente of the Spanish 

 naturalist ; hut there seems to be no good founda- 

 tion for this opinion. Such an accurate observer of 

 nature as Azara was, would never have passed over 

 in silence the extraordinary fleshy lobe which, like

 and no mention whatever is made of this peculiarity 

 in the description of the bird alluded to. (See 

 Azara, iii. 453.)

 deep sooty black colour, uniform over the whole of 

 the plumage excepting the quills ; the first six of

 oblique band of white across their outer webs. The 

 naked skin round the eye is loose, and, in the dead 

 bird, plaited ; perfectly similar, in fact, to that of 

 the Prionops plumatus. 



The female is so differently coloured that it might

 the inner wing-covers are of the same colour, but 

 much paler. The under plumage is dingy white, 

 striped with brown upon the breast and flanks. 

 The bill of the male, even in the dead bird, is 

 straw-coloured yellow, but that of the female has
