three branches of the alimentary canal give off lateral diverticula. 
None of them appear to be ciliated. There are a few other 
points in the section referred to (cf. text-figs.) which deserve to

which are so very abundant in the section near the anterior end. 
But farther back, where the underside is divided into three 
distinct areas, a number of large glands are seen to open on the 
surface towards the sides of the body. These are roughly indi- 
cated on the transverse section (text-fig. 1, g/). They are what 
von Graff described as ‘“‘ Kantendrisen,” and are strictly localized 
to that particular portion of the body. They are deeply stained 
by hematoxylin like the other glands, and their ducts have de- 
formed the epithelial cells between which the glands conduct 
their secretions to the exterior. 
In one important respect these epithelial cells differ from all 
those described by von Graff, namely, in size. He remarks
