Gallus Bankiva of India. 7 
The ‘‘ maxillary processes” are thin and pointed, and ex- 
tend posterior to the point of meeting of the distal end of the 
nasal, on either side. Between the narial apertures the pre- 
maxillary is very narrow, and the osseous culmen formed by 
this bone presents a double arch along its anterior two-thirds; 
one over the nostrils, and the other over the fore-part of the 
beak (Fig. 2). These two curvatures are best seen in the 
skull of the hen bird at my hand. Anteriorly the osseous 
superior mandible is rounded, while its lateral edges are 
sharply caltrate,and beneath, for its fore-part, it is much con- 
caved, as in most Gallince. Hither external narial aperture 
is very large, and of a subelliptical outline, though with the 
arc broader behind than it is in front; while no median, 
bony, internasal septum is developed between these open- 
ings. In the skull of my female specimen the naso-frontal 
sutures are completely obliterated, but they can be faintly 
traced in the skull of the cock (Fig. 3). On the other 
hand, the anterior processes of a nasal bone only partially 
anchylose with the premaxillary above and below, and with 
care these latter bones can be easily detached along their 
sutural lines. A nasal bone is separated from the fellow of 
the opposite side by the median, backward-extending pro- 
cess of the premaxillary, as is the case in most of the 
domestic species. However, Darwin calls attention to the 
fact that in the ‘‘Sultans” (a Turkish breed), ‘‘ the inner 
processes of the nasal bones were ossified together.”* 
A lacrymal in Gallus bankiva is a small scale-like bone, 
sub-triangular in outline, and freely articulated along its 
inner border to the anterior naso-frontal margin of the 
orbit. From its apex in front there descends a delicate 
and semi-spiral spine, twisted from within, outwards, that 
in the prepared skull reaches about half way down to the 
quadrato-jugal bar. 
These lacrymal bones are much alike in a great many 
species of gallinaceous birds, and I found them in all our 
American grouse much as they exist in these wild chickens 
of India + now under consideration (See Figs. 2, 8 and 4).
