The duct from the spermatotheea is small and ciliated. The 
spermatotheca itself is a large, spherical sac, lined with long 
dark-staining, columnar cells. These have large, oval nuclei 
just below the free surface and in the resting condition (in the 
one specimen where the female organs were dormant) appear 
covered with a brown cuticle. In all the other specimens the 
cells lining the spermatotheca were much elongated and pouring 
forth a secretion. The spermatotheca was much more expanded 
in the active than in the dormant specimen and the epithelium 
over part of the surface usually appeared to be more or less 
broken down, perhaps due to the excessive secretion. This 
would make it appear that the spermatotheca is more than a 
mere resting place for the spermatozoa, the function which is 
ascribed to it by Alder and Hancock. The duct from the 
external opening to the spermatotheca leaves very near the 
opening of the duct from the spermatotheca to the oviduct. 
This is at first small but becomes larger and more strongly 
ciliated, and ends close to the opening of the penis in a small 
cpening surrounded by a heavy ring of muscle fibres. 
The oviduct in the dormant specimen appears as a tortuous 
channel lined with short cilia, surrounded by a mass of connec- 
tive tissue, in which lie numerous branching glands. These are 
rather large sacs lined with dark-staining columnar epithe- 
lium, the nuclei of which le at the base of the cells. In the 
dormant state these glands do not differ much from each other, 
but in the active state they become very much changed in 
appearance and differentiate into two types. One becomes very 
much larger, the cells becoming full of a homogeneous secre- 
tion and swollen to a length of 120 microns or more, the cell 
outlines become very indistinct, and the whole mass stains very 
faintly, although the nuclei stain very deeply. The other gland 
is small and lies in the center of the mass, and farther from the 
external opening than the other. It consists of branching tubes 
lined with columnar cells about 80 microns long and with rather 
a large lumen. These cells are sharply differentiated from 
those of the other gland by the fact that they stain deeply 
and the secretion is granular and is poured out into the lumen
