Extract

The fine structure of the shell formed round developing zygotes of an acanthocephalan has been described and compared with the descriptions from light microscopy. The origin of layer 1 from globules in the ovum has been postulated and a sequence of elaboration of the three shell layers has been suggested. The layers of the shell should continue to be numbered rather than labelled with descriptive terms until their origin and chemical composition have been established.

I should like to thank the Avon and Dorset River Authority for collection of the fish.
