of a PufF-bird which Herr von Pelzeln has referred to B. maculatus. They were obtained, as we 

 learn from Herr von Pelzeln's excellent work upon Natterer's ornithological collections, at Cuyaba, 

 Retire, Caicara, and Santarem. These localities are all situated on the eastern extremity of 

 Brazil, immediately adjoining the Bolivian frontier; and it is therefore probable that the species 

 found there is not B. maculatus, but B. striatipectus — its nearly allied Bolivian representative. 

 This is the more likely to be the case, as B. maculatus does not seem to occur at all in the 

 campos of the interior of Brazil, and its recurrence in a district so far removed from the wood- 

 region of the coast as Mato Grosso would be a by no means usual phenomenon *. 



Some years ago I examined specimens of this species in the collection of Prof. Behn at 

 Kiel. These had been obtained by the Professor near Chuquisaca in Bolivia. 



In Prince Bonaparte's ' Conspectus Volucrum Zygodactylorum,' published in the 'Ateneo 

 Italiano ' for 1854, ^^ Nyctactes flammulatus, Verr.," is inserted as a species to follow '^^Nyctactes 

 maculatus." This MS. name refers to the present Puff-bird, as I have ascertained from a 

 specimen of it in the Paris Museum, which is marked " Chaunornis fiammulata, Verr. MS." 

 It was procured by d'Orbigny in the province of Santa Cruz, Bolivia. 



The figure of this species (Plate XXXIII.} is taken from the above-mentioned specimen in 

 my collection. The example in the Strickland collection, which has been kindly lent to me by 

 the Strickland Curator for comparison, is as nearly as possible similar. 



* Herr von Pelzeln has kindlj- re-examined the Nattererian specimens for me since this paragraph was written. It 

 would seem to foUow from what he teUs me that all of them, except those from Santarem, belong to B. strudijoectus, 

 although rather small in their dimensions.
