2. Valves not both the same size.<br />
OC) The epivalve is larger than the hypovalve. Both halves<br />
are broadly and regularly rounded. Gl. Berp;hii 8.<br />
p) Cells are oblong ovoid. The epivalve is smaller than<br />
H. Chromatophores absent.<br />
the hypovalve, more angustate, hemispherical to trunea<br />
tedly conical. The hypovalve is convexo-conical, broader<br />
than the epivalve. Gl. Dangeardii 9.<br />
(a) Cells are roundish; the epivalve is larger than the hypovalve,<br />
and truncatedly conical; the hypovalve is rounded*<br />
Gl. edax 10.<br />
(b) Cells are elongated; the epivalve is cuspidate in the shape<br />
of a long cone, and on the end it is .reunded or drawn out<br />
in a bulbous fashion. The hypovalve is hemispherical.<br />
B. StruCtura of covering known.<br />
Gl. apiculatum 11.<br />
I. Panelling formula: 5'1a7"5"2". Cells are conical, epivalve as<br />
large as or smaller than hypovalve. With apical pore. Epivalve<br />
panelling pattern (apex) is always asymmetrical; panels are<br />
smooth, panelling pattern varying 'greatly. Daughter cells are<br />
freeswimming for a long time, theWattach themselves to Dinobryon<br />
colonies. Cell measures 251t(. No stigma. Gl. dinobryonis 12.<br />
H. Panelling formula: 4 1 2a6n5"2".<br />
Cells are oval, somewhat flattened. Valves both the saine size.<br />
Coverings are occupied by rows of small papillae. Measuring 30-40/t,<br />
No stigma. Gl. Dybowskii 13.
