The writer has in press (1911b) a paper on the telencephalon of 
ganoids and teleosts, dealing especially with certain important features 
not heretofore considered. Among these are certain furrows or sulci 
which seem to me fundamental. The recent paper in this Journal by

Fig. 1. Medial view of the forebrain of Acipenser of 30 em length. The broken 
line s.J. marks the ventricular border of a zona limitans in the brain wall separating 
histologically the primordium hippocampi above from the basal olfactory centers. b.o.

KAPPERS (1911) suggests the present comment on these sulci. Upon 
the ventricular surface of the “lobi anteriores” of ganoids and teleosts 
two furrows are constantly present both in larval and adult life (Fig. 1). 
One of these runs from the preoptic recess dorso-rostrally and bends 
rostrally over the anterior commissure toward the interventricular
