The Fascia Dentata. 
By Dr. G. Extiot Smiru, University of Sydney. 
With 5 Figures. 
The interpretation of the hippocampal region has more than an 
intrinsic interest and importance, for it has such a wide bearing upon 
the problem of the evolution of the cortex cerebri, that it might almost 
be said without exaggeration that the proper understanding of its 
morphology and peculiar phylogenetic history gives one the key to 
interpret the morphogenesis of the whole cortex. That part of the 
hippocampus, which Tarin has called „Fascia dentata‘“ has, from its 
peculiar position and histological features in the higher mammalia, 
always attracted considerable attention, and has been invested with 
a considerable degree of mystery. So that, ever since its recognition 
as a definite region of the brain, there have not been wanting hypo- 
theses, as varied as many of them are ingenious, to explain its mor- 
phology. These hypotheses have been based upon the examination of 
the organ in the adult Eutherian cerebrum, with occasional reference 
to more or less imperfect embryological studies. The most recent at-
