lanceatum and in which the descending and ascending steins of the [ 
uterus cover each other in such a way as to appear as a straight maic 
stem from which lateral ramifications are branching off As far as 
the branches of the intestine extend backwards, it is only exceptional 
to see one or the other uterine coil cross them towards the tnarp: 
of the body ; behind their blind ends the coils extend much nearer to 
the margin and the terminal small triangular appendage is. in perfectly 
mature specimens, almost completely filled with them. Anteriorly the I 
coils are limited by the testicles and the ventral sucker; the utens 
then passes between the latter and the right testicle (i.e. the testiefc I 
opposite the side of the ovary) and in front of this still forms sow I 
small convolutions before entering into the long and thin, but rathe I 
muscular vagina which accompanies the cirrus pouch while desorbing ( 
a number of narrow coils. 
I he eggs have a striking likeness to those of Dicrocoeliu* 
lanceatum ; they are slightly larger than these showing, on an 
average, a length of 0-05 mm. and a width of 0*034 mm.- but apart I 
from that, they present the same oval shape and the same thick shell 
of deep brown colour as these and contain, in addition, a miracidium 
" when fully developed, shows the same two enigmatical strongly , 
reraclive bodies which are peculiar to miracidia of Dicrocoeli** 
lanceatum.
