detached “ oviduct” and thence up to near the last left branchiped. 
The portion of the ovarial string passing through the genital seg- 
ments was slightly moved backward and forwards, apparently by 
some hyaline fibers of the intricate mass of muscles connectec 
with the “ oviduct.” 
A single elongate white ovum (ovum) could be observed in the 
ovarial string in the fourth pest-abdominal segment, near the third, 
during the entire time of observation. 
The cement-glands were’ irregularly distributed in clusters 
around the posterior and middle part of the oviduct, the larger of 
them being between the latter and the male organs. The glands 
were all of a dark-brown color, which did not change during the 
time of observation, and were slowly moved to and fro by the 
network of muscles. The exterior of the female side was com- 
paratively not as largely expanded as usual in normal individuals. 
The internal male organs were of their normal course, shape 
and position; the exterior of the same pre- 
sented, owing tothe pointed lateral protuberance, 
the peculiar figure indicated by drawing Fig. 2, 
dorsal view. The male side was voluminously 
swollen out anteriorly.
