sponding to the line « in figure 2 is sketehed in figure 3a. One sees 
that at one side (in the figure to the right) the Lobulus bifureatus 
is already separated from the rest of the mass 
More backward this lobe assumes in the section the shape of a 
little hood, the two sides of which meet under an obtuse angle. The 
parietes become flat (figure 35) and whilst the connection between 
the two halves in the median-line becomes broader, an offshoot is 
formed from the foremost edge in a frontal direction. In order to 
understand this, one should compare the section figure 35 with the 
level indicated in figure 2 by line 4. We see that this line passes 
successively through this offshoot, the stem of the Lobulus bifurcatus 
and the foremost part of the Hypophysis vesicle. No lumen however 
is to be seen in any of these sections. 
Afterwards a combshaped protuberance develops itself from the 
concave superior plane of the vesiele, penetrating into the concavity 
of the Lobulus bifurcatus (figure 3c). In connection with this the last
