to contain, in addition to a mass of fat and flesh, some of the 
wool of the defunct animal. The “ proventriculus ” was mani¬ 
fested chiefly by the presence of a circle of glands, and a slight 
thickening of the walls of the alimentary canal, rather than by 
actual expansion of it. This glandular area was about 10 mm. 
deep, and gave origin to thirty-five well-developed glands. r \ he 
stomach, which was 150 mm. long, with a pyloric opening 7 mm. 
in diameter, was empty, as the bird had endured a long fast prior 
to the actual meal upon which it was engaged at the time of its 
death. The liver proved to have the right lobe larger than the 
left, in the following proportions:— 
.Right lobe—80 mm. long by 40 mm. wide. 
Left lobe—60 mm. long by 35 mm. wide. 
OSTEOLOGY. 
SKULL. 
The extreme length of the skull between verticals is 122 
mm., or in “ basal length “112 mm. Its width across the fronto- 
zygomatic processes is 67 mm., and 50 mm. deep without the 
lower jaws. The palatines are 27 mm. in extreme width, and 
posteriorly meet the pterygoids upon a transverse suture, but 
do not overlap them. The inter-orbital fenestra is horizontally 
oval. 9 mm. long, and 5 mm. wide, and, as the skull has not been 
macerated, still exists as a fontanel. There is no supra-orbital 
fenestra. The optical foramen, which is vertically oval, is almost 
upon the same level as the inter-orbital, and in a macerated skull 
of similar size measured 6 mm. by 4 mm. In this latter skull 
the inter-orbital was an unsually large fenestra, namely, 13 mm. 
bv 8 mm., this being an individual peculiarity. 1 he depth of 
the beak in the maxillary regions is 26 mm., and its width at 
the maxillary processes 22 mm. The narial aperture is 16 mm. 
by 6 mm. 
1'pon the vertex of the skull there is a median depression 
similar to that found in the chestnut-faced owl. but less strongly 
marked. The quadrato-jugal styles measure 64 mm. in extreme 
length. Tile distance from the occipital condyle to the end of 
the sphenoidal rostrum is 55 mm. in the macerated skull. 
The supra occipital bone is wider than deep, its extreme 
measurements being 50 mm. by 27 mm. From the lower edge 
of the supra occipital ridge to the upper rim ot the foramen
