determination of the specific name of the last I am indebted to Dr. Gunther, to whom 
I sent a skin for identification, as I had not in Edinburgh sufficient materials for com- 
parison. Two of my pupils from Madagascar, Andrianaly and Kajaonai-i, to whom I 
have shown the skins, have very kindly given me the native names with their English 
equivalents. Indris is called “ Simpona,” or the short-tailed ; Propitliecus is “ Varika,” 
or the spotted; and Lemur rufipes is named “Amboan’ala,” or dog of the forest. 
As Propithecus is the genus which is more especially described by M. Milne-Ed wards, 
I shall in the first instance relate what I have seen in that animal. 
Gravid Uterus of Propithecus diadema. 
The uterus of the gravid Propithecus was pear-shaped, with the fundus directed for- 
wards in the abdominal cavity. Its length was 4 inches, its greatest breadth 2J inches. 
A pair of slender Fallopian tubes extended outwards from the side of the uterus ; but 
whilst the left tube was 1^ inch from the free rounded border of the fundus, the right 
was 2 inches, so that the uterus was not symmetrical. Close to the mouth of each tube 
was a pavilion for the lodgment of the ovary, and this gland was attached to the uterus 
by a distinct ligament. The right ovary was about the size of a common pea ; the left 
was double the size, and contained a corpus luteum. A well-marked round ligament 
sprang from the uterus close to the origin of each Fallopian tube, and two broad liga- 
ments, enclosing blood-vessels between their folds, were attached to the sides of the 
uterus. The vagina, 1-^-inch long, was continuous with the wall of the uterus. 
When examined externally, the uterus, though not quite symmetrical, yet seemed as 
if single ; but when the cavity was opened into by a longitudinal incision along the 
posterior wall, it was seen to consist of a corpus uteri and two cornua. The uterus con- 
tained a single foetus, which occupied the corpus uteri and left cornu, which together 
formed the great bulk of the uterus. The right cornu was no bigger than could con- 
tain a hazel-nut, and was so blended with the wall of the enlarged left horn that the 
demarcation between them was not visible externally. The two cornua freely communi- 
cated with the corpus uteri, and a septal fold, half an inch deep, covered on each 
surface with mucous membrane, marked the plane of demarcation between the two 
horns. 
The free surface of the mucous membrane lining the anterior and middle thirds of the 
cavity of the corpus uteri and left cornu was thrown, over the greater part of its extent, 
into numerous shallow convoluted folds, separated by intermediate sulci, constituting 
“une multitude d’anfractuosites irregulieres,” as described by M. A. Milne-Edwards*. 
These folds gave to the mucosa a spongy succulent character. Multitudes of crypt-like 
recesses were situated on the summits and sides of the folds, as well as at the bottom of 
the intermediate sulci. Scattered amidst these folds were upwards of twenty irregularly 
elongated areas of the mucosa, in which the folds and crypts were either absent alto- 
gether or much diminished in size and relative numbers. The largest of these areas was
