son. Rosa suggests that the duct leading from the sac also 
corresponds, and that it will be found to open in Eudrilus, as 
it does in Teleudrilus, into the receptaculum ovorum. It 
must be admitted that this suggestion, based upon the very im- 
perfect description which I was able to give of this part of 
the reproductive system, is not unreasonable. 
I am, however, now able to state that the duct in question 
has no relations with the receptaculum of segment x1v, but 
opens into the spermatheca just opposite to the 
opening of the oviduct of segment xiv, and is lined 
throughout with a cubical epithelium, quite continu- 
ous with that which forms the inner layer of the 
spermathecal duct. 
I now pass to the consideration of the organ in the fourteenth 
segment which I have termed “ ovary,” but which Rosa con- 
siders to be nothing more than a receptaculum ovorum homo- 
logous with that of other Earthworms. 
Rosa found that the oviducts of Teleudrilus open sepa- 
rately from the spermatheca on a line with the dorsal pair of 
sete ; the spermathece open into an atrium, which itself opens 
on to the median ventral line of the body; the oviducts, how- 
ever, agree with those of Eudrilus in having a thick muscular 
layer and in their continuity with the receptaculum ; it appears, 
however, from the figure which Rosa gives (388, pl. ix, fig. 5) that 
the oviduct opens by a funnel into the ccelomic sac which con- 
nects the ovary and the receptaculum, and only just enters the 
Jatter; its relations to the receptaculum are, in fact, much like 
those of Lumbricus, except that the greater part of the funnel, 
which in Lumbricus depends freely into the interior of seg- 
ment xu, is here enclosed by the forward extension of the 
receptaculum. This receptaculum has its cavity subdivided 
by numerous trabeculz, a condition which is also met with in 
the receptacula of other Earthworms. The contents of the 
receptaculum consisted of mature ova and numerous smaller 
cells probably serving for their nutrition. Rosa suggests that 
this may also be the case with Eudrilus, that the “ developing 
ova” described by myself in that worm might be merely such
