the oviduct describes its convolutions in its course towards the uterus. 
The stroma ovarii contained at its periphery a few advancing ovisacs 
about a line in diameter. 
Each cornu uteri is about 1 foot 4 inches in length, and of a nearly 
uniform circumference of 2 inches. It is beset with narrow, wrinkled, 
oblique, irregular ruge, forming longitudinal elevations as they ap- 
proach the body of the uterus, and again becoming oblique—patches 
of the rugous surfaces alternating with smooth patches. 
The common uterus presenis large, longitudinal, wrinkled rugze 
for the first inch of its extent, and then a spiral valve begins to be 
formed, about 2 lines in thickness, which describes thirteen close 
coils before subsiding in the common vagina ; the length of the spiral 
portion, which may be compared to the ‘cervix uteri,’ is 33 inches ; 
the length of the vagina is 4 inches. The rug of the vagina are 
longitudinal, and longer at its beginning and end, where they termi- 
nate on a well-defined circular fold, dividing the vagina from the uro- 
genital canal, and constricting the orifice; the free borders of the 
spiral valve are beset by free, fine, longitudinal folds of the lining 
membrane of the uterus. 
The urethra is about 3 inches in length, and becomes closely con- 
nected with the vagina 2 inches before it terminates. Its orifice is 
defended by two longitudinal folds. 
In comparison with the Common Hog, the Wart-Hog, as regards 
its internal anatomy, differs in the more simple form of the stomach, 
the relatively shorter small intestines, and the relatively longer large 
ones ; but, like the Common Hog, the czecum is small, and the colon 
disposed in spiral coils, in both which characters they resemble the 
Ruminants ; the cecum is broader in proportion to its length than 
in the Common Hog. In both the Common Hog and Wart-Hog 
the intestinal canal is more tied down by the fat-laden processes of 
peritoneum, and appears to have less motion allowed it, than in other 
quadrupeds. The liver and gall-bladder, the kidneys and the tho- 
racic viscera, much resemble those of the Common Hog. The inner 
surface of the jejunum shows a reticulate disposition of rugze in the 
Common Hog, but not the regular longitudinal folds in the duode- 
num and beginning of the jejunum, as in the Wart-Hog. 
The epiglottis passes into the posterior nares in both the Wart-Hog 
and Common Hog, and has the hyo-epiglottidei muscles ; but the pha- 
rynx in the Common Hog does not present the superadded sacculi, 
nor the larynx those peculiarities which distinguish the Wart-Hogs. 
These resemble the Babyrussa in the sacculated structure of the 
pharynx, but differ in the more simple stomach. The Wart-Hog 
differs from the Common Hog in the smaller size and more simple 
form of the ovaria, and the fewer mammze. The most marked dif- 
ference from all other Suide, and that which best justifies the generic 
separation, is presented by the dentition of the Phacocherus; the 
modifications of the alimentary canal are not of the same degree.
