to the cavity of the glomerulus, in addition to being connected 
with the duct of the head kidney, was connected also by a tubule

diverticulum; d, central duct with a tubule just opening into it; gl., glomerulus; 
t, two tubules; the lower one opening by a nephrostome into the cavity containing 
the glomerulus, while the upper one is beginning to divide into two branches, both 
of which open into the cavity a few sections farther on. A tubule is seen lying 
freely in the venous diverticulum; farther on this divides into two branches, 
one of which opens into the pericardial cavity and the other into the cavity of 
the glomerulus. This is the only case of the kind met with.

may be found between the head kidney and the functional kidney, 
but connected wihh neither.
