Summary

A sub-epithelial collagenous layer and pits in the skin have been described inOxychilus spp. The collagen is especially developed beneath the skin on the right side of the body inO. helveticus. It seems to arise from pore cells which previous authors have described in other molluscs. The pits inO. helveticus are lined by cells which together exhibit a gradation of electron densities. This probably represents an accumulation of secretory material and a macroapocrine secretory process has been observed.

Zusammenfassung

Bei denOxychilus-Arten wurden eine sub-epitheliale Kollagenschicht und Vertiefungen in der Haut beschrieben. Das Kollagen ist besonders ausgebildet unter der HautoberflÄche der rechten Körperseite inO. helveticus. Dies scheint aus den „pore cells“ hervorzugehen, was auch von früheren Autoren in anderen Mollusken beobachtet wurde. Die Vertiefungen inO. helveticus sind umgeben von Zellen, die zusammen eine Abstufung von Elektronendichte zeigen. Wahrscheinlich representiert dies eine Ansammlung von Sekret-Material; ein macroapokriner Sekretionsvorgang wurde beobachtet.
