Summary

Cells filled with large inclusions and with processes abutting on the walls of an extensive system of blood sinuses in the brain of architeuthoid cephalopods appear to have a secretory function. The inclusions measure up to 2.1 μ in diameter and stain with paraldehydefuchsin. The characteristics in favour of the homology of the cells with large inclusions with the neurons of the “neurosecretory system of the vena cava” (Alexandrowicz, 1964, 1965) are presented.

Additional information

The tissue to be described here has first been noted in prepared sections belonging to Prof. J. Z. Young, F.R.S., during a stay at London under the sponsorship of the Deutsche Forschungsgemeinschaft. I am greatly indepted to Prof. Young for permission to study his collection of cephalopod brains. Fishing of living animals at Naples has been supported by grant NONR (2100) through the Anton and Reinhard Dohrn foundation. I would like to thank Prof. H. A. Bern and R. S. Nishioka for criticism of the manuscript.
