of the oviducts of the adult female, with uterine segments of moderate size. 
There were four openings into the cloaca. 
The following hurried notes were made when the condition was first 
noticed, and were handed to me together with the specimen. “Terminal 
portions of oviducts distended with eggs ready to be laid. There were eggs 
also in the middle portions of the oviducts. These were extracted and 
among them was a considerable number of empty spheres of albumen, 
v.€. the albumen envelope was present but egg not contained therein. The 
proportion of these empty spheres was about one-fifth, at a rough estimate.” 
On section, the right gonad proved to be entirely ovarian in structure. 
It contained ova in all stages of development, but the connective tissue was 
everywhere hyperplastic, and a considerable number of the ova showed signs 
of degeneration. Polygonal masses of pigment were present apart from ova in 
great numbers, and the thickened wall of the ovary encroached upon its cavity. 
The left gonad consisted mainly of tissues similar to those of the right, 
but the hyperplasia of the connective tissue, the presence of the piginent in 
excess, and the degeneration of the ova, were more pronounced. ‘The three 
nodules upon the inner border had the structure of normal functional testis, 
and though in close and intimate contact with, yet were discrete from, the 
pathological ovarian tissues. The line of junction between the two tissues 
was very irregular, so that the ovarian pigment seemed to invade the 
spermatic tissues along the lines of the intertubular connective tissue. . 
Perfectly normal spermatozoa were seen to be aggregated at one point in 
a dilation of a vas cffcvrens in connection with the middle lobule of testis- 
substance (Fig. 6). Vasa efferentia connected the right ovary to its kidney. 
The uterine segment contained only spurious ova with nuclei of granular 
debris. The peritoneum about the suspensory ligaments of the gonads bore 
ciliated epithelium upon the surface. There was nothing unusual about the 
pituitary or suprarenal bodies. Further dissection showed that the bones 
of the fore-limb were of the male pattern, though of but moderate 
development.

Right gonad, measuring 15 x 7 x 7 mm., consisted of two distinct portions. 
The inner and larger portion had the appearance of normal testis, and its
