Extract

The observations here recorded were made as a result of a suggestion by Professor Orton. While examining material of Psammechinus miliaris he noted the presence of C-shaped spicules in the gonad. He kindly passed the material on to me, suggesting that an examination of other common Echinoids might prove interesting.
