This monograph describes the results of studies of fossil
and recent Silicotlagellates of the Indian Ocean along with
some from the Arabian Sea and the South Pacific. The publication
describes structure, biostratigraphy, and taxonomy of
the Silicoflagellates.
Numerous electron micrographs, line-drawings,
and diagrams illustrate the text.
