292 Part III.—Twenty-fourth Annual Report 
only one case was the hermaphrodite organ symmetrical—that was a case 
described by Weber, in which a testis was attached to the posterior end 
of each ovary. In no case was the united organ composed equally of one 
testis and one ovary. The connection of the vas deferens with the ovary 
was similar in Howe’s, Masterman’s, and the present instance, except 
that in Howe’s a well-marked valve structure prevented the back passage 
of ova into the vas deferens. A somewhat similar arrangement appeared 
in Masterman’s specimen. 
Kylet describes a case of hermaphroditism in the ling (Molva vulgaris). 
The testis was in four parts ; a very large part much larger than the ovary 
was attached to the anterior end of each ovary, and a smaller part was 
connected with the hind end of each ovary, that connected to the right 
ovary being very small. A small portion of the left ovary was separated 
from the ovary posteriorly. Anteriorly each testis opened into the ovary 
by a small aperture guarded against the issue of the eggs by a valve-like 
fold of fibrous tissue. Posteriorly the left testis opened by its vas deferens 
into the oviduct. In this specimen, then, we have a combination of the 
two conditions described above— viz., (1) the ovary functioning as a vas 
deferens, and (2) the common use of the oviduct for the issue of both 
eggs and sperms. The eggs were nearly ripe, and the testis was well 
developed. The specimen was secured in May.
