duplication or papilloma formation within the gland. 
A section of cornu near the perforation shows a milder 
degree of endometritis, more areas of cellular infiltrate, 
degeneration and hemorrhage. 
For over two years this animal had a discharge from the 
vagina about every eight weeks ; as this occurred regularly 
after coition it was looked upon as a miscarriage. No 
blood observed until March discharge and none after- 
wards. The animal died in May. 
3656. Bennett's Wallaby. {Macropus rufficolisbennetti). 
This adult female wallaby furnished a very interesting 
specimen for our museum. This specimen consists of the 
entire pelvic portion showing the genitalia and marsupial 
pouch in which is found a newly extruded fetus. The 
opening of the marsupial pouch, which is distended, is 
7 X 5.5 cm. wide and 14 cm. deep and has the capacity of 
about a pint. The right posterior nipple is not developed, 
showing as a papilla on the lining of the pouch. The right 
anterior nipple has been developed and measures 1 cm. 
long. The left posterior nipple has the same size and 
general appearance as the right anterior and the left 
anterior is the one to which the present young is attached. 
It is a tubular structure 4 cm. long, with 5 mm. as the 
average diameter, presenting at the distal end a somewhat 
bulbous enlargement. The pouch is lined with smooth 
epithelial walls composed of somewhat thickened skin. 
The young one is covered with a white smooth skin, 
entirely hairless. It measures 4 cm. total length, occipito- 
mental 15 mm., biparietal 8 mm. The mouth is triangular 
in outline, nostrils well developed; eyes show as black 
papillae and covered by membrane. The fore legs are 
well developed and the nails well formed. The hind legs 
are short and rudimentary, the nails beginning to be hard. 
The tail is short and thick. The external genitalia is 
present as a small tubercle with a passage in the center but 
the sex is indeterminate. There is a transverse scar 
evidently the result of decidual attachment.
