title: A comparison of the periodic substructure of the trichocysts of the Cryptophyceae and Prasinophyceae.
abstract: A study of the trichocysts of the Cryptophyceae and Prasinophyceae has confirmed the general concept of their structures as advanced by Hovasse, Mignot, and Joyon (1967) and Manton (1968) respectively. In Cryptomonas 58 a staining method using ruthenium red reveals a uniform and regular substructure within the fabric of the trichocyst ribbon. A finer and less regular substructure was observed in the trichocyst of Pyramimonas parkeae.
