in Eminodrilus.! The gizzard lies in Somite vi. There 
are no calciferous glands, no typhlosole, nor intestinal czca. 
The tubular intestine is slightly dilated in Somites vi1, viz, 
and enters the sacculated intestine in Somite xv. 
Lateral hearts occur in Somites x1, x11, x111, xiv, the first 
three being moniliform. 
In accordance with the variations in positions of their pores, 
the nephridia lie latero-ventrally or latero-dorsally (figs. 4, 5), 
and exhibit slight differences in the mode of convolution of 
the tube and in other points. The inner (ventral) nephridium 
has a large cecal portion to the bladder directed dorsally, while 
that of the dorsal nephridium is but feebly developed, the 
nephridiopore being placed near the end of the bladder (fig. 5). 
There is no nephridial network nor communication between 
the nephridia. 
Tue GENITAL System. 
The testes and ovaries have the usual position. There are 
three pairs of sperm-sacs in Somites x, x1, x11, that of the left 
side in Somite x11 being much smaller than the right one 
(fig. 3). 
The prostates are enormous, and there is but one pair of 
them. Each consists of two parts (figs.8 and 6),—a soft, more 
or less cylindrical portion, which is white, glandular, con- 
stricted, and convoluted (prst.) ; and a short, narrow, shining 
duct (pe. d.). The latter opens externally in Somite xvir, and 
passes backwards into Somite xrx, where it joins the glandular 
region ; this passes still further back to the 24th somite, and 
then bends forwards on itself, its free end (a) lying in Somite 
xvil, at the side of the duct.? 
Lying above the prostate is a sac containing a bundle of 
penial cheetz (pe. s.) nearly as long as the prostate—that 
is about a quarter of an inch (figs. 6,7). This penial sac opens

the prostate.
