- Title
THE MARINE IDATOM <em>ETHMODISCUS REX</em>: ITS MORPHOLOGY AND OCCURRENCE IN THE PLANKTON OF THE SARGASSO SEA.

- Abstract
Living cells of the diatom Ethmodiscus rex (Rattray) Wiseman & Hendey 1953 were found in the plankton of the southern Sargasso Sea. Apparently, this is the first report of E. rex from the plankton of the Atlantic Ocean. Scanning electron microscopy of peroxide-cleaned frustless revealed some new morphological features for this species. When viewed from inside the frustule, the puncta appear as rimmed pits. From outside the frustule, they appear to be shallow depressions with a small opening at the bottom. The so-called mucous tubules in the center of the valve were seen from the outside to be elongate slits and from the inside as obliquely directed flattened cylinders which cap the tubes.
