VI. A MONOGRAPH OF THE RAMPHASTIDA, OR FAMILY 
OF TOUCANS. 1 Volume, Imperial Folio, containing Fifty- 
two Plates, with descriptive letterpress, &c. Price £12 12s. 
London, 1854. 
An edition of this work was published in 1834, at the price of £7; 
but the extensive researches since carried on among the Great Andean 
Ranges of South America having led to the discovery of many additional 
and beautiful species belonging to this extraordinary group of Birds, a 
revision of the work not only became necessary, but an entirely new 
edition was deemed imperative ; and accordingly one, with the whole 
of the former Plates redrawn, was published in 1854, at the price of 
£12 12s. 
The history of this South-American group is very peculiar; and their 
manners and actions are as remarkable as their aspect, in some respects 
reminding us of the Hornbills of India and Africa, while in others they 
are unlike those of any other group of the feathered race. To a con- 
sideration of these points the Introduction is devoted. 
VII. A MONOGRAPH OF THE TROGONIDA, OR FAMILY 
OF TROGONS. 1 Volume, Imperial Folio, containing Thirty- 
six Plates, with descriptive letterpress. Price £8. London, 
1838. 
This work, in unison with the Monograph of the Toucans, comprises 
the history and figures of all the species of the group known up to the 
date of publication. The members of the Trogonide are remarkable for 
a gorgeous style of colouring, for recluse habits, and for the union of 
insect diet with such aliments as fruits and berries, in accordance with 
which the beak is modified; they ave divided between the warmer lati- 
tudes of America and India, with the exception of one species, which is 
peculiar to Africa, With the plumes of some species the Mexican kings 
and Caciques are said to have adorned their head-dresses. 
The same reasons which induced the Author to publish a new edition 
of the Monograph of the Ramphastide, have also rendered another edition 
of this Monograph desirable ; and accordingly one is now in preparation, 
comprising all the new species and information required respecting this 
family of birds during the last twenty-five years. It will be completed 
in four Parts, at £3 5s. each, the tirst and second of which is now ready 
for delivery. 
VIII. A MONOGRAPH OF THE ODONTOPHORINA, OR 
PARTRIDGES OF AMERICA. — 1 Volume, Imperial Folio, 
containing Thirty-two Plates, with descriptive letterpress. 
Price £8 8s. London, 1850, 
The interest which attaches to this work is threefold. First, it displays, 
even to the most unpractised eye, the broad distinction which subsists 
between the Partridges of America and those of Europe ; secondly, the 
species are all remarkable for the elegance of their forms and for the chaste 
beauty of their colouring ; and thirdly, at no distant date these Birds will 
be regarded in America, as our Partridges in Europe are, as game, and 
perhaps preserved by law,—their flesh being as delicate for the table as 
that of our ordinary bird, from which, however, they differ considerably 
in the structure of the beak, and in general habits and economy,
