Based on the results, it has found that six distinct layers can be identified from lateral to medial in the olfactory bulbs, and the adults have more cells than the subadults. Ventricles of the adults take up larger vacuity, have richer choroids plexus, and primordial pallium and primordial hippocampus of them are more developed than the subadults, in which the primordial piriform is well-developed. Ventral to the primordial hippocampus, there is a septal area which can not be divided into medial and lateral parts in both adults and subadults, nor there is lateral limiting sulcus to separate the primordial piriform and the corpus striatum, but only in the subadults, a medial limiting sulcus can be clearly identified to separate the primordial hippocampus and the septal area. Besides, the corpus striatum of Onychodactylus fischeri is paleostriatum. The cell group that located at two sides of the third ventricle is amygdale, and shape and size of neurons within the telencephalon are poorly differentiation.
