564, Prasinocladus subsalsus Davis.

Euglenopsis subsalsa Davis, Annals of Botany, Vol. VIII, p. 378, PI.
XIX, 1894.

Salt marshes of the Charles River, Cambridge, Massachusetts,
growing very densely, forming a green velvet on marsh grass, etc., near
the surface of the water. Autumn, 1894.

B. M. DAVIS.

In December, 1894, were published descriptions of two new genera,
evidently similar if not identical organisms; Prasinocladus lubricus Kuckuck,
Biologische Anstalt auf Helgoland, Vol. I, p. 261; and Euglenopsis subsalsa
Davis, Annals of Botany, 1. c.

It now appears that the name Euglenopsis was used by Klebs, Zeitschrift
fuer Wisseuschaftliche Zoologie, Vol. LV, p. 367, 1892, for an organism
resembling Euglena.

The author of Euglenopsis subsalsa accepts this as a sufficient reason
for accepting Prasinocladus, without raising the question of the animal
nature of the organism described by Klebs , but is inclined to think that P.
subsalsus and P. lubricus should be kept as distinct species ; although it is
possible that Kuckuck’s form, growing under more natural conditions than
those described by him, might prove to be identical with P. subsalsus.
