CONTRIBUTIONS TO THE ANATOMY OF EARTHWORMS, 475 
thodrilus which probably correspond to the ‘ pericardial 
glands” of Lumbriculus. These consist of a network of capil- 
laries with numerous spherical dilations crowded with cells ; 
the whole network forms a compact series of organs clothed 
with chloragogen cells; they are found in the anterior 
segments only, and exhibit a more or less perfectly metameric 
arrangement. 
(12) Description of a series of paired sacs attached to the 
septa of Acanthodrilus georgianus, which appear to be 
special glycogenic organs.
