hroad. Sporangia oval, frequently o f a golden colour,
usuallg solitary, hut sometimes binary ; cells next the sporangia
inflated.

This is a very distinct species, as also a very beautiful object
under the microscope. There can be no doubt about the
synonyme of M. Léon le Clerc.

Char. Filaments smaller than those o f V. pulchella, terminated
by long colourless cilia. Cells about three times as
long as broad. Sporangia oval, lodged in cells o f the same
form.

The presence of cilia on the extremities of the filaments
renders this a very remarkable species, and one hy Avhich it
may be readily recognized. There is an evident analogy
between the genera Vesiculifera and Bulboclmte, and through
V. ciliata there would appear to be an easy transition from
the one to the other.

Char. Filaments o f considerable diameter. Cells scarcely so
long as broad. Sporangia circular, contained in inflated
cells o f the same form, and which are usually solitary.

The above is a very beautiful species under the microscope:
it is to be distinguished from all others by the shortness of its
cells. In the Herbarium of Dr. Greville I find a specimen of
this species, not indeed in a state of reproduction, put up by
M. Chauvin, and marked with doubt as Conferva dissiliens
Lyngb. I t is certainly not the Conferva dissiliens, either of
Dillwyn’s work, or of “ Fnglish Botany,” th a t of the latter
work being probably identical with Desmidium mucosum.

Char. Filaments o f much less diameter than those o f V. pulchella.
Cells fiv e or six times as long as broad. Sporangia
circular, placed in much inflated cells, which may be compared
to a heart inform.

This species would appear to be an uncommon one, for I
have only twice met with it.
