pearas three, they continue to do so till they unite and per- 
haps even after this. The cells of the sac are most developed, 
. about the middle of the cellular part, they are not formed 
from the inner surface of the wall itself, but between this 
and the inner tubes, no nuclei were visible. 
Above the cellular part of the perfect sac, are nucellar ag- 
gregations and in the same there is alike tendency below, no 
cells developed in the sheath. 
The inner tubes are articulate towards the apex of the 
cellular part, and probably also once or twice in this part.
