306 DISEASE IN WILD MAMMALS AND BIRDS 
affected were three carnivores, one rodent and 
one marsupial. 
No particularly important association of tliis sal- 
pingitis and other pathology was noted, and indeed the 
only noteworthy lesion of the organ under discussion is 
now to be cited. 
Nylghaie {Boselaphus tragocamelus) . Chronic vaginitis, fibroma 
uteri, chronic tuberculous salpingitis. The vulva and lower half of the 
vagina are covered by a thin coating of yellowish mucus. Mucosa is 
mottled purple, irregular, in some places smooth and flat, and in others 
showing clear cysts with yellowish fluid contents. The upper part of 
the vagina shows a pedunculated fibroid extending from the cervix. 
This tumor measures 32 x 20 mm., and is attached to the posterior 
cervical wall by a broad pedicle and is of smooth surface. The right 
uterine wall shows a large fibroid which tw'ists the uterine lumen to the 
left. The tumor in the right uterine cornu is nodular, measures 11 x 9 
X 7 cm., shows many dilated veins coursing over the surface and one 
section shows a soft central necrotic area. The left uterine cornu 
shows a small fibroid at the lower end. There is a chronic endometritis 
present. The outer half of the right tube is the seat of firm nodular 
swellings, one of which proves to be a purulent salpingitis (tubercu- 
lous), the others calcareocaseous salpingitis. Both ovaries are fibroid 
and cystic. Microscopic section shows some exfoliation of the epithe- 
lium of the vagina. The uterine cornu is thickened and the fibrous 
tissue is greatly increased. The tube is the seat of a purulent salpingitis 
with an occasional broken down tubercle present. The ovaries show a 
mild degree of oophoritis (Fig. 23). 
Obstructions to Continuity of Birth Canal. 
Obstruction to the lumen of the genital canal was 
observed in three mammals. 
An American Bison {Bison bison), five years old and known to have 
been in captivity three years died of a chronic gastroenteritis and 
pulmonary parasites after many weeks of failing health. At autopsy 
a double hydrosalpinx, and probably unilateral hydrometra, with low 
grade cystic oophoritis were found. A picture is reproduced. The 
notes are not perfectly clear as to the anatomy but from the gross speci- 
men in preservative it would seem that the left uterine cornu was 
involved in the dilatation (Fig. 24). 
Lion cub {Felts leo) had congenital cystic uterus. The only abnor- 
mality found is in connection with the internal genitalia. The vagina 
is 50 mm. long, uterus 23 mm. long, horns of uterus each 90 mm. long.
