Abstract

The ciliated epithelial sensory cells of the tentacle papillae and of the concave epipodial sense organ (e.s.o.) surface of the trochids Margaretes helicinus, Gibbula cineraria, G. umbilicalis, Monodonta lineata, Diloma nigerrima and D. zealandica are primary sensory cells with intra-epithelial nuclei. The 5–7 cells of a single papilla bear many cilia. Each e.s.o. cell has one cilium surrounded by 8–9 specialized microvilli. Both kinds of sensory cell show structural similarities with known mechanoreceptors.
