308 DISEASE IN WILD MAMMALS AND BIRDS 
TUMOES. 
Tumors of this tract in the mammals have been con- 
fined to the uterus proper, none having been found in the 
vagina, tubes or ovaries; in birds one oviductal growth 
and two ovarian tumors are recorded. These tumors are 
reported briefly according to their histological structures, 
a brief summary being added at the end. 
A Black Lemur {Lemur macaco) showed a local leiomyofibromatous 
nodule on the lateral aspect of the uterine body near the cornu. 
A nine-banded Armadillo {Tatu novemcinctus) gave an interesting 
specimen which can be described as follows: The uterus is enlarged 
so that it measures 90 mm. from external os to fundus. Tubes and 
ovaries apparently normal. There is considerable grumous blood in the 
vagina and cervix ; the former is normal. The cervix is pale and opaque 
in its lower half; upper half is slightly congested and mucosa decidedly 
rugous. The uterus itself shows an attenuated muscular wall with a 
thickened irregular mucosa which is the seat of pseudomembranous tabs 
of a dull red color, while the mucous membrane itself is irregularly red 
and j^ellow; also some grumous blood in the cavity. The size of the 
uterus is due to a large fibroma attached to the left lateral wall near 
the cornu. The mucous membrane of this is irregularly disturbed in 
some places, the tumor being partly bare. Here and there the mucous 
membrane shows the same degenerating hypertrophic character as seen 
on uterine wall. The tumor is attached to the wall by a narrow pedun- 
cle (Fig. 25). 
A nylghaie with multiple fibromata has already been described. 
A Jaguar {Felis onca) presented in the middle of the right uterine 
cornu a cystic resilient tumor 3x4 cm., which proved to be a fibro- 
adenoma. 
A lioness (Felis leo) presented a penetrating malignant adenoma of 
the uterine cervix upon which an active endometritis was implanted. 
The tumor penetrated the uterine wall, which gave way, an acute fatal 
peritonitis resulting. Metastases had occurred to the lung. 
A ^Yild Boar {Siis scrofa) had a generalized ulcerating carcinoma 
of the uterine body. 
An instance of chorion-epithelioma in a Canada porcupine is 
worthy of separate description. 
Canada Porcupine (Erethizon dorsatus dorsatiis). Acute suppura- 
tive catarrhal endometritis, hemorrhage in myometrium, chorion-epithe- 
lioma. In anterior abdominal wall a short quill was found imbedded. 
A very small quill was imbedded in the retrocervical muscles. A quill 
about 2 cm. long lies free in the peritoneal cavity attached by recent 
plastic adhesions to peritoneum over left pubic ramus. A fourth quill 
was adherent by recent fibrous lesions to anterior wall of cecum. Peri- 
toneum contains a moderate excess of thin watery fluid. Liver and
