As will be seen from the accompanying drawing (text-fig. 38), 
the spermatophore consists of a globular swelling followed by a 
long thin tube. The sperm, which appears blackish in glycerine 
preparations, is limited to the spherical or nearly spherical recep- 
tacle at the distal end of the case. The spermatophore, as will be 
Text-fig. 38. 
Spermatophore of Pareudrilus sp. 
also apparent from the figure referred to, is of an elegant form, 
not precisely corresponding to that of the spermatheca in which 
it lies. The swollen and globular receptacle of the sperm is not 
more than one-third of the length of the “ stalk,” which reaches 
down to the very mouth of the spermatheca. At its termination the 
walls of the spermatophore project in a ring-like fashion ; a state of 
affairs exactly recalling the spermatophores of the Tubificidee, and 
of the genus Stuhlmannia among the Eudrilide. No doubt the ~ 
shape is due to a moulding upon the walls of the spermatheca ; 
but the state of preservation of the specimens does not enable me 
to give details. The walls of the spermatophore appear to be firm 
and thick, and rather brittle in consistency. In teased prepara- 
tions the rupture of the stalk was invariably a clean fracture. 
The walls are fibrous in appearance, and of the usual pale brown 
colour that is generally associated with chitimous membranes. The 
extremity of the tube, 7. e. that which is nearest to the mouth of 
the spermatheca, is open; the other end is quite blind. The
