Subclass 1. .Flagella on one end of the cell;
no grooves present. Covering is
either a solid, firm membrane, or
develobed as armor. In the latter
case, it consists of two portions,
separated by a suture. These portions
are not composed of plates.

end of the cell; grooves (and flagella)
are visible during at least
one stage of the life cycle. The
transverse groove usually divides
the entire cell into an anterior
and a posterior section (called
"valves" in armored forms).
• II. Diniferae (P:100)
8 Lindemann (loc. cit.) designated the group,of the Peridineae
as a "division" and'accordingly designated
(Dinoflagellatae)
the three sub-groups as - "subdivisions". He subdivided the latter
1-nto "classes", which, in turn, are again subdivided into vfamilies".-
According to his classification, therefore, the i'eridinae are
represented by.3 classes,
w.nce tne feriainpae are regarded as a class throughout
the present volume, we shall follow a different method of .
designating the groups; this class is here divided into subclasses,
which are divided-into orders'and, further, into
families.
