medial wall described by His as the fissura prima. 
Fig. 41 Through the tela chorioidea telencephali medii. The primordial 
hippocampus is bounded by the sulcus limitans hippocampi ventrally, and by the 
neopallium dorsally. The lamination of the neopallial cortex is easily dis- 
cernible. Ventral to the sulcus limitans hippocampi is the septum ependymale. 
Emerging from the matrix a narrow marginal velum is seen.
