The single specimen sent by Mr. Foster is not altogether 

 identical with the example obtained by Prof. Graham Kerr 

 on the Lower Pilcomayo. The latter specimen is the only 

 one in the British Museum with which I could compare 

 the Paraguay bird, so that 1 cannot draw any conclusions as 

 to their specific identity or distinctness, as Prof. Kerr's bird 

 is in very poor condition ; but I should not be surprised 

 to hear that they are considered distinct, as the Sapucay 

 bird is not only more rufesceut, but has less barring on the 

 breast and abdomen. Further specimens are necessary, 

 however, to determine this question. 



Azara says that, according to the natives, this bird 

 frequents the large forests only, and is solitaiy in its habits. 

 It lays four eggs of a glossy greyish colour [N.B. — Vieillot 

 translates morados lustrados as " violet lustre" but Azara's 

 colour is the correct one.] 



Mr. Foster remarks that : " this is a very rare bird : one 

 specimen only was brought to me one day by a boy, who 

 had snared it in the monte. Nothing is known as to its 

 habits/'
