Sect. III. p. 139*

Hab.-In fossis, Atlantic States.

Four to six times longer than broad; from the front cylindrical,
not attenuate at the trunoately rounded ends; viewed laterally
fusiform, attenuated from the middle to the rounded ends; cytio-
derm striately punctate,

REMARKS.- The central constriction is more apparent in the lateral
than front view. When the frond is full of endoohrome the puno-
tae on the outer wall are not apparentt but when it is empty
they are seen to be small, and closely arranged in stria-like
rows. This species extends through all the Atlantic sea-board
States. Prof. Bailey has found it in South Carolina and Florida,
as well as in Rhode Island, I have collected it in Centre County,
of this State.
