318 Mr. O. Salvin's Sijnopsis 



An examination of the type of Kaup's S. ruficoronata at 

 once shows that Prof. Baird's views respecting it were correct 

 in every way ; and I propose to supply the deficiency as regards 

 the name of this species by calling it Setoj)haga bairdi. 



Its difi'erence from the true S. ruficoronata is obvious when 

 the two birds are compared together. The chestnut crown of 

 S. bairdi is surrounded on all sides by blacky which colour, 

 narrow towards the nape, extends across the forehead. The 

 whole sides of the head are also black, with the exception of 

 a ring round the eye and the lores, which are yellow. In S. 

 ruficoronata the chestnut crown meets the yellow round the 

 eye and the yellow forehead without any black intervening, 

 and the side of the face beneath the eye is also yellow, being 

 separated from the yellow of the under surface by a very 

 narrow dark line ; the black patch on the nape is considerably 

 larger. 



In examining a large series of 5. bairdi, some specimens 

 show that the black of the forehead is rather variable in 

 amount; but a black superciliary streak is always present, 

 and the extent of the yellow round the eye does not seem 

 to exceed the amount shown in the figure (Plate VIII. fig. 1). 



As regards the distribution of this species, we have no 

 evidence as yet that it is found outside the limits of the 

 Republic of Ecuador. Mr. Sclater included the name S. rufi- 

 coronata in his list of the birds of Santa Fe de Bogota; but 

 this must be considered to refer to the true S. ruficoronata, 

 and not to the present species. 



The figure has been taken from a specimen in our collection 

 obtained by Buckley at Sical, in Ecuador.
