THE GENERAL SUBJECT.

and other characters are, however, Passerine. The peculiarity of 
its sternum, taken with its tarsal scutellation and the form of the 
syrinx, induce the autlior to follow Garrod and place it as a primary 
division of the Tracheophone Passeres under the name of Gonopopha- 
GIDA3, which he defines Jis Tracheophonine Passeres, with a holorhinal 
skull and four-notched sternum, an exaspidian tarsus and a syrinx with 
no intrinsic muscles, and with the sterno-tracheales not attached to the 
proceasus vocales.

The author’s dissections of Parra jacana and Metopidius africanus^ and 
O'. her researches, show that the Parridcn are in no degree related to the 
Rails, but form a separate group to be placed amongst the Limicolce as 
restricted by Nitzsch. In a foot-note (p. 639) it is proposed to substitute 
the word Pluviales as a name for the non-columbine Charadriiformcs (the 
Limicolce of Garrod), to correspond with the other division Columbce 
(including the Columhidca and Pteroclidoi) of that great group. The 
osteology of the Parridm is discussed, with woodcuts of the sternum, 
shoulder-girdle, and wing-bones of Metopidius albinucha ; and the radius 
in the latter genus is shown to be peculiarly modified, whereas in Parra 
and Hydropliasianus it presents the ordinary form.

Dissection shows that this Petrel is not a true Procellaria^ and it is 
made the type of a new genus Garrodia, which, together with OceaniteSy 
Pclagodromay and Fregetta, compose a well-marked family of the 
TubinareSy which it is proposed to call OceanitidcCy as distinguished from 
the remainder of the group, or Falmaridce of Garrod.

In the simplicity of the structure of its lower larynx. Apteryx stands 
on the same level as Struthio ; but in the Casuariidce there are 
peculiarities in the structure of the bifurcating trachea not existing in the 
other Ratitce. In Rlieay there is a highly-specialized and peculiar syrinx, 
provided with a pair of intrinsic muscles, in which respect it differs from 
all the other members of the sub-class. Illustrative woodcuts are given 
with the text.

Portions of the provinces of Pernambuco and Parahyba do Norte are 
graphically described ; and notes on the 116 species observed contain some 
important facts on geographical distribution. The Sertoes of Pernam- 
buco appear to be the northern limit of Cariama cristatay and also prove 
to bo the habitat of Rhea macrorhyncha.
