nodular and on opening shows some mural fibroids and 
a thick brown mucilaginous material in the lumen. 
3824. Hairy-rumped Agouti (Dasyprocta prymnolopha) . 
Dystocia. An apparently normal fetus occupies the left 
uterine horn. The nose has engaged in the pelvis and has 
been moulded in a curve pointing to the right. The fetus 
measures — bitemporal 30 mm., cervical coronal 31 mm., 
length of fetus 17 mm. Pelvic inlet in the fresh state 
measures 18 mm. transversely and about 17 mm. anterio- 
posteriorly. The umbilical cord is 10 cm. long and appears 
normal as do the membranes. Placenta presents as a 
spherical mass of hard dense consistency, 35 mm. in diam- 
eter, and with apparently normal placental tissue oc- 
cupying the lower border of this spherical mass. On 
section the mass shows areas of alternating soft red tissue 
separated by communicating trabeculse of dense white 
fibrous tissue. This mass is distinctly encapsulated, but 
the nature of the enclosing membrane is indeterminate. 
The pelvis in dry state shows evidences of malformation 
due to trauma. The right ileum is pushed forward and 
inward carrying the acetabulum a short distance inward 
and backward. There is a marked thickening about the 
right acetabulum. At the upper portion of symphysis 
there is marked bending backward toward the sacrum 
with thickening of the bone. The last sacral vertebra 
is sharply bent and anchylosed, forming an angle of 
60°. The pelvic measurements in the dry state — at 
superior strait transverse 24 mm., right oblique 23 mm., 
left oblique 26 mm., true conjugate 22 mm., outlet 17 mm. 
between the ischiatic spines. This is obviously a 
traumatic malformation and forms a relatively contracted 
pelvis. The delivery of an adult fetus is impossible. 
3834. 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 being smooth and flat, 
and in others showing clear cysts with yellowish fluid 
contents. The upper part of the vagina shows a peduncu-
