caudally toward the fore brain (usually 
near the cavity), and give off collaterals 
which rise toward the glomerular zone. 
The neurites are varicose and sinuous, ~ 
of medium thickness and not very uni- 
form. The collaterals are slender and 
smooth. 
4) Stellate cells of the glomerular 
zone. — These appear as stellate or fusi- 
form cells in sections tangential to the 
surface. They are situated in the inner 
part of the glomerular zone and have 
their dendrites parallel with the surface. 
The cell bodies measure 12—16 by 
12—32 u, and the dendrites usually have 
a wide expansion, sometimes exceeding 
one millimeter (Fig. P). The branches 
of the dendrites present characteristic 
varicosities or nodosities and enter into 
the formation of numerous glomeruli. 
In the few cases in which I have found 
the neurites they are directed centrally 
or caudally. 
5) Spindle cells of the granular 
zone (Fig. Q). — These are spindle
