When I drew up the characters of Bucco inacrorhynchits, as given 

 in the * Annals of Nat. Hist.' for May 1854, p. 357, I had not in my 

 possession specimens of the true macrarhynchus from Cayenne, and 

 consequently confounded with it the present bird. But the much 

 larger size of the bill and whole body, the greater extension of the 

 white colour on the front, the narrower black band and the total 

 absence of any fawn-coloured tinge on the belly and vent are quite 

 sufficient to distmguish this Bucco from its Cayenne representative. 



I have lately ascertained, through the kindness of Prince Bona- 

 parte, that this is the species included under the name Tamatia 

 hyperrlojnchus in his Conspectus Volucnan Zygodactylorum, pub- 

 lished in the 'Ateneo Italiano' of May last, and I have thereforje 

 adopted his specific designation. But no descriptions have yet 

 appeared of the many new species of which the names only are inserted 

 in that and other similar recent publications of the Prince. 



The type specimens of the present bird are in the French National 

 collection.

A single s})ecimen of this bird in the British Museum was procured 

 by Mr. Dyson in Honduras. In my Synopsis of this family I have 

 confounded it with its near affines, from which I now think, as 

 might have been expected from the locality, it will bear separation. 

 It is very proljable that Prince Bonaparte's name, gigas (which was 

 api)lied to a bird brought by Delattre from Nicaragua), was intended 

 for this same species, but as the type has disappeared, and no 

 specific characters have been published for the name, it is difficult 

 to be certain on that point.
