bladder is large. The spleen is elongate, 4:^ in. long and ~ in. wide, 
and being on the left side of the great omentum. The kidneys lobular, 
2^ in. long, and \^ in. wide, upper edge and front surface flatter. The 
hilus is wide and posteriorly directed, each lobule having an indepen- 
dent infundibulum. The ovaries are not encapsulated. The Fallopian 
tubes are about 4 inches long. The transverse mesocolon and the 
ascending layers of the great omentum are more united than in the com- 
mon otter or badger. The mesocolon and mesentery have a single root. 
The pharyngeal walls are lined with thick rugose mucous membrane. 
The velum is rounded with no uvula, tonsils are sheltered behind valvular 
folds with their concavities backwards, a number of elongate papillae 
are arranged along the sides of the palato-glossal folds. The tongue is 
smooth with a median depressed raphe, circumvallate papillae are 
more numerous on the right side than on the left; a minute circum- 
vallate papilla is in place of the foramen coecum. The entire surface 
of the tongue is closely beset with fungiform papillae ; its front edge 
is semicircular, thin, sharp, serrated by the prominence of the papillae, 
not emarginate. The length of the tongue is about 3 inches, the inferior 
surface being free for about half an inch. The ceratohyal on the 
right side was sharp and presented an adventitious angle. 
The middle constrictor of the pharynx and sternoh3'Oid are inserted 
into the thyrohygal cornua, and the stylo-ceratic fills up the angle 
between the two cornua. Thyroceratic is in front of the superior laryn- 
geal nerve. The crico- thyroid is very extensive, but made up of short 
fibres. The inferior constrictor of the pharynx is very thick ; crico- 
arytenoideus posticus is very large ; the hinder edge of the cricoid 
cartilage is carinate. The true vocal chords are very sharp, the chink 
of the glottis narrow, the ventricle of the larynx small, no sacculus 
laryngis. The false vocal cords are small folds. The epiglottis is tri- 
angular, having the fraenum attached nearly to its apex ; the inferior 
cornua of the thyroid cartilage are long, curved, firmly attached to the 
side of the cricoid. The crico-arytenoideus lateralis is small. The 
thryro-arytenoid much larger. The lower part of the larynx is very 
wdde, suddenly narrowing to the chink of the glottis ; the cuneiform 
body is a soft connective lobule, external to the corniculum of the ary- 
tenoid; ary tenoideus proprius is weak ; the first ring of trachea is im- 
perfectly double, and on the right side short, all the other rings make 
seven-eighths of a circle. There are 54 rings in the trachea ; the upper 
bronchus comes ofi" on the right side almost at the level of the bifurca- 
tion. The right lung consists of the three ordinary lobes and the azygos 
lobe, the latter being double; its two parts are separated by the vena 
cava inferior and phrenic nerve ; the left lung is bilobed. The pericar- 
dium is perfectly free from the diaphragm. The heart is oblong, not 
sharply triangular. There is a long right superior vena cava and no 
left, a very large vena azygos; no vestigial fold of Marshall; a cylin- 
drical inferior vena cava. The aorta gives off an innominate, from 
which arise the two carotids and the right subclavian. The inferior vena 
cava is a little dilated at its opening. The greater Eustachian valve is
