visible either. Later stages are shown in fig.494 B—D, where the gonimoblast has arisen 
as several outgrowths from the lower and lateral sides of the auxiliary cell. The 
long cell or cell-complex at the upper face of the auxiliary cell probably derives 
from the carpogonial branch. It must be admitted that the fertilisation and the 
connection of the auxiliary cell with the carpogonium has not been ascertained. As 
to the first point reference may, however, be made to fig. 491 A where a pit in the 
wall of the trichogyne is undoubtedly the trace of a fusion with a spermatium. 
Kyrın (1928, p. 54) has emphasized the accord- 
ance that exists in several respects between this 
species and Stenogramme interrupta; the develop- 
ment of the gonimoblast here pointed out is in 
good agreement with this conception. The carpo- 
gonium reminds one of that in Jridwa cordata
