Abstract
Acanthocephalus jacksoni and Echinorhynchus gadi acanthors have four enveloping membranes. A literature review indicates many inconsistencies concerning the description and number of acanthor membranes even within a single species. The greatest variation observed in the membranes is in the "fibrillar coat." The membranes are more easily observed in fresh, unfixed smears of eggs. It is recommended that the traditional citing of three membranes as the typical description be reviewed with the suggestion that four membranes are typical for the acanthor stage.
