of southern Mexico represents a southward restriction of descen- 
dants of these Eocene forms. It is also similar to Mespilodaphne 
hispaniolana Berry of the Miocene of the Island of Haiti*®. It is 
much like numerous existing species of Mespilodaphne. The genus 
contains numerous existing species confined to the American tropics. 
Occurrence.—Isthmian railroad 3? km. north of Palomares on the 
Saravia estate, State of Oaxaca.

Goeppertia tertiaria Berry, Proc. U. 8S. Nat. Mus., vol. 59, p. 176, pl. 25, fig. 1, 
1921. 
Leaves of medium size, elliptical oval in general outline, widest 
below the middle, with an acute tip and a rounded base. Margins 
entire, full and evenly rounded. Texture coriaceous. Length about 
12 cm. Maximum width about 5.75 cm. Petiole missing.  Pri- 
maries three, supra basilar, all prominent on the lower surface of 
the leaf, the midrib stoutest; the laterals diverge from the midrib 
about 5 mm. above its base, at acute angles of about 25°, curving 
upward. Secondaries comprise a few camptodrome pairs in the tip 
of the leaf, several broadly curved ascending ones from the outer 
sides of the lateral primaries, and an opposite pair from near the 
base of the midrib. The tertiaries are thin and percurrent, or in- 
osculate midway between the primaries or secondaries and primaries. 
Areolation a fine polygonal lauraceous mesh. 
This is a type commonly referred to Cinnamomum and I know of 
no certain characters for distinguishing certain species of Goeppertia 
and Oryptocarya from that genus, and am therefore inconsistent in 
not adhering to custom. The present species is very similar to several 
species of Goeppertia, a genus with numerous existing species con- 
fined to the American tropics, and I am also influenced by the large 
number of almost exclusively tropical American species of the tribe 
Oryptocaryeae that have leaves of the Cinnamomum type. The pres- 
ent species was described originally from the Miocene of Costa 
Rica and is represented by a single, slightly smaller fragment in the 
Mexican Miocene, which is certainly very closely allied to, if not 
identical with, the Costa Rican type.
