510 MESSRS. SCLATER AND SALVIN ON THE CRACID&. [June 9, 
to O. poliocephala by Cassin. We have given our reasons below for 
considering Mr. Lawrence’s determination as correct. 
(1860.) Mr. G. R. Gray publishes a synopsis of the genus of 
Penelope in this Society’s ‘ Proceedings,’ giving short Latin charac- 
ters of all the species known to him. Four species are described as 
RIEMVS RES-== G. R. Gray. (Of this Synopsis.) 
P. nigricapilla = P. obscura. 
P. bridgesi = P. obscura. 
P. selateri = P. sclatert. 
P. lichtensteinit = P. argyrotis. 
(1860.) Salvin, in the second volume of ‘ The Ibis’ (p. 248), gives 
full details of the history of the Oreophasis derbyanus, which was 
previously entirely unknown except from Mr. Gray’s figure. 
(186-?.) Prof. Reichenbach publishes his ‘ Volistindigste Natur- 
geschichte der Tauben und Taubenartigen Vogel,” forming part of 
his ‘ Handbuch der speciellen Ornithologie.’ We cannot find any 
date attached to any part of this work, and therefore cannot give 
the exact date of issue. Reichenbach divides the natural family 
Cracide into two groups—Cracine and Penelopine, and, in order to 
fill up the voids in the number of his ridiculous quaternary system, 
associates with them the Didine and Microdactyline (i.e. the 
Cariamas), and constitutes out of this heterogeneous mass his family 
“ Alectorine,”’ the fourth division of his ‘ Columbarie.’”’ Reichen- 
bach’s account of the genera and species of Cracid@ is, as regards 
merit, about on a par with the above-mentioned arrangement of the 
higher divisions of the group. It is evidently a wretched compilation, 
written mainly without reference to original specimens. No less than 
four new species of Craz and one of Penelope are sought to be 
established solely upon figures of the older authors; and Cras itself 
is subdivided into four subgenera (Crax, Mituporanga, Crosso- 
laryngus, and Spherolaryngus), the very distinct Crax urumutum 
being left among the typical Craces! Ortalida leucogastra and 
O. albiventris are referred to the genus Chamepetes! Penelopsis 
(established in the ‘ Avy. Syst. Nat.’ as Penelops) is here transferred, 
to become the type of a genus uniting P. rufiventris of Tschudi 
and P. adspersa of the same author ! 
(1866.) Mr. G. R. Gray describes, in this Society’s ‘ Proceedings,’ 
a new species of Penelope, P. greeyi, from a specimen living in the 
Society’s gardens. 
(1867.) Mr. G. R. Gray publishes his ‘ List of specimens of Birds 
of the Order Gallinz in the British Museum.’ In this important 
work the Cracide are arranged as the second family of the order, 
the first being the Pteroclide, and the third the Megapodide. This 
is no doubt very nearly its natural position, as the Pteroclide are 
still more nearly allied to the Columbe than the Peristeropodous 
Galline. As in his ‘ Genera of Birds,’ Mr. Gray divides the Cracide 
into two subfamilies, Penelopine and Cracine. To the former sub- 
family are referred three genera (Penelope, Ortalida, and Oreophasis), 
containing altogether thirty-five species represented in the national
