Abstract
DURING an investigation of mucous secretion on the proboscis of Harrimania kupfferi1 ultra-thin sections were made of the epithelium of various parts of the body including proboscis, collar and the anterior parts of the trunk. In the epithelium of the ventral part of the trunk, immediately behind the collar, a distinct choanocyte type of cell was encountered.
