The ovaries were not seen in this specimen, but I have 
found that they occupy the normal position in the 13th seg- 
ment. Apparently they are enclosed in a large sac which ex- 
tends from the septum bounding the 11thand12thsegments. This 
sac (see fig. 9) is somewhat pear-shaped; it gradually narrows 
to a fine tube which opens into the large spermatothecal sac. 
The latter opens on to the exterior between the Segments 
xtv/xv. The pear-shaped sac, which I believe involves the 
ovary, is the ‘ovarialblase”? of Michaelsen. A narrow and 
short tube leads from it to the egg-sac, which occupies the 
usual position attached to the anterior wall of the 14th seg- 
ment. From the egg-sac leads another tube, which appears to 
open into the ovarian sac. This tube, as 1 have ascertained 
from a continual series of sections through the entire appa- 
ratus, only lies within the ovarian sac; its lumen does not 
communicate with that of the ovarian sac; the tube soon issues 
again from the sac, and opens on to the exterior by the ovi- 
ducal pore. The first tube mentioned which connects the 
egg-sac with the ovarian sac is really a portion of the funnel 
of the oviduct—that portion which in other Oligocheta does 
not open into the egg-sac, but freely into the cavity of the 13th 
segment. As in the present species, there is a sac developed 
which involves the ovary; it must happen that the funnel 
partly communicates with the sac in question. As the latter 
grows a stretch is put upon the funnel which grows out in the 
way that we see. The spermatothecal sac is a large pouch 
which is somewhat bilobed at its free extremity. This region 
lies posteriorly to the end which opens on to the exterior. In 
sections it is seen to be lined by an epithelium which is 
columnar in form, and shows no signs of that proliferation so 
frequently seen in the spermatothecal sacs of these Annelids. 
Its interior is folded. 
The male organs of generation are as in many other 
Eudrilids. There are two pairs of testes situated in Segments 
x and x1; the sperm sacs are in Segments x1 and x11, and, like 
the testes, are attached to the front walls of their segments. 
The sperm-ducts retain their distinctness until their point of
