Notwithstanding what Mr. Cassin says, it must at least 

 remain doubtful whether Hahn's figure was really intended 

 to represent this form of M. bonariensis; but it is hardly 

 necessary to change the name. On examining a pair of 

 birds received from Lima (which must, I suppose, belong 

 to Cassin's M. purpurascens) , and comparing them with a 

 series of M. bonai'iensis, I can find very little difference 

 in the males, except that the bill and feet are rather 

 stronger. The female of M. purpurascens is paler and more 

 fuscous above, and very much paler and moi'e whitish on the 

 lower plumage.
