Abstract
1. Test secretion and metamorphosis in Folliculina aculeata and Folliculina elegans are described. 2. These processes may be divided into the following six stages: a. The free-swimming stage. b. The stage of cement secretion. c. The secretion of the body of the test. d. The secretion of the neck of the test, during which process the animal puts forth a long, proboscis-like projection. This stage is, as far as is known, peculiar to F. aculeata, F. elegans and F. viridis and has not been described before in detail. e. The secretion of the collar of the test. f. Formation of the peristomeal lobes characteristic of the adult.This publication has 0 references indexed in Scilit:
