The present investigation was undertaken to examine the nonsiliceous ultra-structure of diatoms (BacilIariophyta) by means of freeze fracture electron microscopy. Freeze fracture procedures are complicated by the difficulties encountered in fracturing silica-based components and the removal of these materials subsequent to replica casting. Supplementary data was obtained through conventional thin section methodologies. This report is a prelim¬inary account of observations made on selected nonsiliceous, cellular con¬stituents of Thalassiosira antarctica Comber, a planktonic, marine diatom.
