Abstract
1. Pontigulasia vas will not reproduce unless shell materials are present in the cultures. 2. The shell materials are collected for a period of approximately four hours immediately before division. 3. There are no changes in the nucleus until almost all the shell materials are collected. Nuclear changes are begun, however, before the formation of the new shell.This publication has 0 references indexed in Scilit:
