chus of Leadbeater— belonging to the genus Prionirhrjnchus. Now 

 upon referring again to Spix's figure and description, I think that he 

 is as hkcly to have iutended one bird as the other for his P. Martii, 

 and it will be difficult to prouounce decisively vvhich of the two 

 ought to bear that name, until the type iu the Munich Museum, if 

 stiU existing, be examined, and the fact ascertained whether it i's a 

 specimen oi Momotus semirufus or Prionirhynchus platyrhynchus.

The Prince Maximilian found this Motmot singly or in pairs in 

 the woods of the south-eastern provinces of Brazil. He savs it was 

 generally observed sitting quietly upon a branch likę a Bucco, and 

 allowing the hunter to approach without fear. Especially in the 

 morning and evening it emits its prolonged, soft, flute-like note, re- 

 sembling that of our European Hoopoe. Its food eonsists of insects. 



This bird, which is well figured by Le Vailliant in the Supplement 

 to his ' Promerops, &c.,' pi. B, is sometimes called rufcajnllus ; but 

 that name is more strictly applicable to the species represented by 

 the šame author in his ' Oiseaux de Paradis,' pi. 39, and of which 

 some account will be found hereafter. 



Although I have never yet had an opportunity of examining Para- 

 guay specimens of this species, there seems little doubt that Azara's 

 " Tutu " is referable to it, and we mušt therefore employ Vieillot's 

 term "cyanogaster" as its first-given specific appellation, although 

 m most examples the blue tinge onthe belly is but slightly apparent.
