into the side-chambers of the pharyngeal pocket is attached to the 
walls of these chambers. Plate lll, Fig. 19 shows that the alimen- 
tary system has numerous branches, and also that the beadlike 
intestinal branches are densely gathered. These, moreover, send 
out projections both to the dorsal and the ventral sides. These 
partly separated sacs have above all an assimilatory function. Some 
oval dark bodies of quite a considerable size may be seen on 
Plate III, Fig. 20 (cb). These merely represent excremental masses 
that are stored in the lumina of the intestinal coeca (text-fig. 16). 
In order to accommodate these gatherings, the gut has expanded

enormously, and the intestinal epithelium is very low and shows 
neither secretory nor assimilative features. Otherwise the intestine 
indicates a most abundant intracellular digestion. 
Female genital organs: As in Cr. ivahlbergi, the ovaries 
lie dorsally. They are still. minute, as the oocytes as yet lack yolk- 
granules. The oviducts proceed from the dorsal side of the ovaries 
and form thick canals arranged somewhat like network. Although 
the ovaries are so immature, the oviducts possess a distinet lumen. 
Uteri are present in the form of two long coiling canals, which 
do not branch as in certain Stylochus-sptc'iQS. 
The female apparatus is principally similar to that of Cr. ivahl- 
bergi, thus equipped with ductus vaginalis lacking an outer opening 
of its own. A short antrum femininum leads direetly upwards from 
the female genital pore. This distinetly represents a dilatation. The 
vagina proceeds from its anterior wall, while ductus vaginalis issues 
from its upper end. The vagina runs straight forwards parallel 
to the ventral side of the animal, later approaches this side still 
more, then makes a sharp curve upwards and backwards. This 
ventral limb of the vagina is longer than that of Cr. wahlbergi. 
The lumen of the vagina changes its shape after the curve has 
been made. Its former tubular shape now becomes twisting. This
