contains tlie branches Grypaires/^ Pliaetornaires/' Campy- 
lopteraires/^ Lampornaires/^ Doryferaires/^ and ^'Leuco- 
liaires," the last being further subdivided into the boughs 
Leucoliates/^ Amaziliates/^ Hylocharates/^ and ^^Chloro- 
lampates.^'’ The second section is composed of the branches 
Trochiliaires/^ Florisugaires/’ Petasophoraires/^ Calli- 
peridiaires/^ Thaluraniaires/^ and Avocettinaires.^^ The 
Ornismiens contain two divisions^ each subdivided into two 
sections, which, as before, are unnamed. Of the first division, 
the first section is composed of tlie branches Patagonaires,^^ 
Chrysolampaires,^^ Clytolemaires,^^ and Diphlogenaires,^^ 
and the second of the branches ^^Euclosiaires,^^ ^^Eriocnemaires,^^ 
Aglseactaires,^^ Adelomiaires,^^ and Lophornaires,^^ the last 
containing the boughs Oxypogonates and Lophornates.^'’ 
Of the second division, the first section is composed of the 
branches Melisugaires,’^ Platuraires,^^ and Lesbiaifes,^^ and 
the second of the branches Amathusiaires,^^ Zephyritaires/^ 
Selasphoraires,^^ and Ornismiaires.^^ The different branches 
and boughs, for so we translate the words branches and 
rameaux,^^ are further subdivided into 70 genera, including 
29 subgenera ; and, Mr. Gould having, in his ^ Introduction to 
the Trochilidae^ (1861), recognized 123 genera, we should be 
inclined to look upon Prof. MulsanPs arrangement as an im- 
provement, but for the belief that his reduction in their number 
seems to be obtained in some cases by totally ignoring certain 
of his predecessor's divisions, while, on the other hand, the use 
of so many groups larger than genera deprives the present work 
of a very desirable simplicity ; but the fact, which is highly 
creditable to him, remains to be mentioned that characters 
which are more or less definite are assigned to each group of 
species, whether larger than a genus or less, named or unnamed. 
Eleven new genera and 13 new subgenera are proposed, not 
always perhaps with a good show of reason, while several 
others are employed in a sense very different from that attri- 
buted to them by Mr. Gould. Prof. Mulsant also takes a good 
many liberties with the spelling of scientific names, his object 
being to facilitate their pronunciation, regardless of orthography. 
Three hundred and seventy species are enumerated; but we 
regret to add that four new ones are mentioned by name without 
any description — a practice which is deserving of the strongest ' 
reprobation. The authors announce, we are glad to say, that 
this essay is intended as the precursor of a larger work on the 
subject, of which they hope soon to begin the publication. (Cf. 
Ibis, 1867, pp. 126-129.) 
LeucoUa is a new genuS; to which thirteen species are assigned, the first
