2. CHARACTERS OF SOME APPARENTLY New SPECIES oF Bucco- 
NID, ACCOMPANIED BY A GEOGRAPHICAL TABLE OF THE 
FAMILY. By Puitip Lutriey Scrater, M.A., F.L.S. 
(Aves, Pl. CV. CVI.) 
1. Bucco HyYPERRHYNCHUs. (PI. CV.) 
Tamatia hyperrhynchus, Bp. MS. et Consp. Vol. Zygodact. p. 13. 
B. supra fulgenti-niger ; fronte lata et superciliis anticis albis : 
subtus albus, nigro late torquatus ; lateribus nigro radiatis : 
rostro maximo. 
Long. tota 10°5; ale 4°5; caudze 3:5; rostri a rictu 2°1. 
Hab. In regionibus fl. Amazonum superioris (Hawawell). Mus. 
Paris. et P. L. 8S. 
When I drew up the characters of Bucco macrorhynchus, as given 
in the ‘ Annals of Nat. Hist.’ for May last (p. 357), I had not in my 
possession specimens of the true macrorhynchus 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 distinguish 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 
hyperrhynchus in his Conspectus Volucrum Zygodactylorum, pub- 
lished in the ‘ Ateneo Italiano’ of May last, and I have therefore 
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. 
2. Bucco pysont. 
Tamatia gigas, Bp. Consp. Vol. Zygodact. p. 13? 
Bucco dysoni, G. R. Gray in Mus. Brit. 
B. supra fulgenti-niger ; fronte usque ad oculos et collari postico 
albis: subtus albus ; vitta pectorali lata nigra ; lateribus nigro 
variis ; rostro pedibusque nigris. 
Long. tota 9°7; alee 4°5; caude 3°4; rostri a rictu 1°8. 
Hab. In America Centrali, Honduras (Dyson). Mus. Brit. 
Obs. Species a Buccone macrorhyncho fronte latius albo, rostro 
majore, et ventre pure albo, a Buccone hyperrhyncho rostro minore 
et fronte minus albo diversa, et inter has duas media locanda. 
A single specimen 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 probable that Prince Bonaparte’s name, gigas (which was 
applied to a bird brought by Delattre from Nicaragua), was intended
