rising at the same time, and finally join into a single median 
duet, the glandular canal. The oviduct is characterized by the 
possession of ciliated epithelial cells, beneath which comes a thin 
muscular coating, and between which open numerous glands 
for some little distance before forming a common duct. 
The glandular canal pursues a course obliquely forwards and 
downwards, and finally opens into the vestibulum at a point 
on the right side, after receiving in its course a short duct from

above, which stands in communication with one of the intestinal 
coeca, so that there is, as in the Heterocotylean Trematodes, 
a genito-intestinal canal. This is similar to that deseribed by 
Geba (11)im Am. tristriata andAm. mediostriata. 
The canals are constructed in the same manner as the oviduct, 
and are lhned with an epithelium composed of ciliated columnar 
cells ; outside this is a thin muscular layer.
