The first of these papers contains an historical introduction to the study of
Infusoria, a short exposition and resume of their structure, and descriptions
of forty-two known species. In No. 2 twenty-eight marine species occurring
at Warberg are described, of which eleven are considered new by the author.
In No. 3 a list of thirty Infusoria is given as observed in the sea at Wisby,

GREEPF (I. c.) has made some most interesting observations
on the integumentary, digestive, and reproductive systems of

of these creatures certain pear-shaped or oval bodies, which he
considers to be true trichocysts, and thinks that the staff-shaped
bodies described as such in other Infusoria are neither trichocysts
nor touch-corpuscles, but skeletal organs. Greeff has also
observed in the same species an apparent distinction of sex,
hair-shaped bodies like spermatozoa becoming developed in the
