and the cells lining the spermatothecal sac. This specimen 
was remarkable for a plug of cells filling the lumen of the sac 
just where it narrows towards the pore. The plug of cells pro- 
jects a little way into the lumen, as shown in the figure (fig. 16), 
and is furthermore rendered obvious by its less staining and by 
a fibrous appearance with scattered nuclei. In the more 
mature worm I could distinguish no such plug. Underneath 
the epidermis the mass of cells forming this plug spreads out 
into a more extensive layer. 
One of the three individuals which I examined by longitudinal 
sections showed a difference from the typical structure of the 
genus in the presence of two pairs of sperm-duct funnels. To 
these corresponded two pairs of testes. The additional pair 
was in Segment x. This segment, like the following, was filled 
with a mass of developing sperm not contained in a sperm-sac 
or sperm reservoir. In other particulars I could detect no 
differences from other specimens. It should be stated, how- 
ever, that the penial setz could not be studied. These setz 
are, of course, frequently most useful in distinguishing species. 
It must, therefore, be left undecided as to whether this worm 
is a distinct species of Eudriloides or is only a variety of 
Eudriloides Cotterilli. 
Eudriloides brunneus, n. sp. (figs. 2, 10, 21—28). 
Of this new species of Eudriloides I have examined four 
examples; two were dissected and two examined by means of 
transverse sections. 
As compared with the first species of Eudriloides described 
in the present communication, this is large ; itis not, however, 
quite so large as Michaelsen’s Eudriloides gypsatus. 
The colour of the species was of a uniform greyish brown 
(after preservation in alcohol) ; the sete are exceedingly minute, 
so as to be quite invisible when the worm is examined by a 
hand lens alone. Michaelsen has commented upon the minute 
sete of Eudriloides gypsatus. 
The clitellum was not very distinct ; it appears to occupy 
the greater part of Segments xtv—xvu1; the clitellum is not
