8), _Echinospora_, Leger, and _Diaspora_,
Leger; most of these forms are from Myriapods.

Genus _Adelea_, Schn. Dizoic spores; sporocysts round or oval, plain.
Several species are included in this well-known genus, among them
being _A. ovata_, _A. mesnili_, _A. dimidiata_; most of them are
parasitic in Insects or Myriapods.

Genus _Minchinia_, Labbe. Dizoic spores; the sporocysts are produced
at each pole into a long filament. _M. chitonis_, from the liver of
_Chiton_ (Mollusca).

Genus _Klossia_, Schn. The spores are tetrazoic (or perhaps polyzoic).
_K. helicina_ from the kidney of various land-snails is the best-known
form. Usually said to have 5 to 6 spores, but Mesnil considers that
the normal number is 4, as is the case in another species, _K. soror_.

Genus _Caryotropha_, Siedlecki. Many spherical spores (about 20) each
with 12 sporozoites. _C. mesnilii_, unique species, from the
spermatogonial (testis) cells of _Polymnia_ (a Polychaete). An
interesting point in the schizogony is the formation of schizontocytes
(see above).

A Coccidian parasitic in the kidneys of the mouse has been described
by Smith and Johnson (1902) and named by them _Klossiella_, on the
ground that it possessed many spores, each with about 20 sporozoites.
Woodcock has shown, however, that the authors were in all probability
dealing with a similar modification of schizogony to that which
obtains in _Caryotropha_. The sporogony of this form (and hence its
systematic position) remains at present, therefore, quite unknown.

There are several doubtful or insufficiently known genera, e.g.
_Bananella_, _Goussia_, _Hyaloklossia_, _Gonobia_, _Pfeifferella_ and
_Rhabdospora_, many of which probably represent only schizogonous
generations of other forms. (For information concerning these see
Labbe, 1897.)

Lastly it remains to mention the extremely interesting forms parasitic
in Cephalopods. For some years these have provided a fruitful source
of discussion to systematists. Here it may be stated simply that their
systematic position and nomenclature were thought to have been finally
settled by the researches of Jacquemet (1903) and Luhe (1902) in the
following terms:--

Genus _Eucoccidium_. Luhe (syn. _Legerina_ Jacq.), Coccidia possessing
polysporous oocysts and lacking schizogony, parasitic in Cephalopods.
Two well-known species: _E. eberthi_ (Labbe), (=_Benedenia_ se
