other known form. It seems to be a somewhat older type, since
it has been recognized in the consideraNy older deposits of the
Patapsco formation in Virginia. It would be interesting to
know from what horizori or horizons ir_ the Raritarl it had been
collected, bu_ PrM. Newberry failed to indicate the locality in
connection with any of his several specimens, and it has not
been collected since his day.

Descrlptlo_.--Leaves unknown. Species based on fruits
(samara) which resemble greatly those of the modern red maple
of this latitude. They are somewhat varigble in appearance, in
the size of the carpel and in the outline of the wing, but these
are interpreted as examples of variability such as may readily
be seen in examining a series of fruits of the modern species.
The carpel proper varies in diameter from 3 ram. by 2 ram., to
7 mm_ by 3 mm., the latter probably being nearer the normal
form:. The wing varies in length from I cm. to 1.7 cm., probably
averaging' about i. 5 cm. and in breadth from 5 ram. to 9 mm.
The lower margin is thickened and cnrved (straight in one
specimen) with the characteristic paralleI, curving, occasioilally
forked veins.
'Although these remains are fairly common and seem clearly
allied to Acer, no leaves of this genus have been discovered in
