310 DISEASE IN WILD MAMMALS AND BIRDS 
adenomata of the cystic type, one malignant adenoma, 
one adenocarcinoma, and one chorion-epithelioma. They 
were found in Lemures 1, Carnivora 2, Ungulata 2, Pro- 
boscidea 1, Rodentia 1, and Edentata 1. Metastases 
occurred but once, to the lung. No secondary tumors were 
found in the uterus. 
While upon the subject of neoplasms of the female 
genitalia, it may be well to describe the three instances 
found in the avian organs. A very definite case of adeno- 
carcinoma occurred in the oviduct of an Undulated Grass 
Parrakeet {Melopsittacus undulatus), a variety of bird 
very susceptible to neoplasms. The notes in an abbre- 
viated form are given : 
Immediately under the ovary is an irregular mass measuring 2 cm. 
long, 1 cm. wide, 1 cm. deep. The lower part of the tumor thus comes 
to press against the cloaca. It is adherent anteriorly to the peritoneum. 
It apparently consists of two parts, an upper rounded larger, and 
a lower spherical smaller. Both parts are Avell encapsulated 
and separated from each other by a well defined constriction. 
The upper part has a pale opalescent appearance. It cut easily with 
moderate resistance. The lower portion externally has an egg-yellow 
color streaked with red. Upon section it has the same general appear- 
ance but contains in addition numerous small, irregular, yellow areas 
which mask the general opalescent appearance. The centre of this node 
contains an empty space (cyst) 1x2 mm. Microscopic section consists 
of an oval or elliptical mass showing over one convexity a depression 
simulating a constriction. A thin fibrous capsule extends over most of 
the section which is extra thick at the point of constriction. Constriction 
roughly divides the section into two. The upper portion consists of 
one or two coarse septa of fibrous tissue. From these central areas a 
delicate connective tissue framework extends peripherally. In this 
framework are great numbers of irregular gland spaces. These gland 
spaces are so closely placed in most cases that room is afforded for but 
one nucleus of the bundle. The gland spaces vary in size, some large, 
some small, and show grotesque shapes. The larger gland spaces here 
contain granular debris and pyknotic nuclei. Compound granule cells 
suggesting colostrum corpuscles may be seen in this debris. The epi- 
thelium of the gland spaces consists of a single layer of columnar 
epithelium of low cuboidal type. In places it is heaped up so as to 
present several layers. In places too it is not applied in a regular 
manner to the basement membrane but breaks through and then the 
cells extend in most disorderly fashion into the lymphatics of the
