are the terminal attenuations of large rays, or belong to a species of 
feather of fan palm, can not be conclusively determined. Similar 
broken rays in the muds of estuaries and coastal lagoons are frequent 
in warm latitudes at the present time. 
Occurrence.—Isthmian railroad ? km. north of Palomares on Sa- 
ravia estate, State of Oaxaca. 
Holotype.—Cat. No. 36813, U.S. N. M. 
Class DICOTYLEDONAE. 
Order URTICALES. 
Family MORACEAE. 
Genus COUSSAPOA Aublet. 
COUSSAPOA VERACRUZIANA, new species. 
Plate 2. 
Leaves of large size, broadly ovate in general outline, widest 
medianly, with a bluntly pointed tip and a wide cordate base. Mar- 
gins entire, slightly undulate. Texture coriaceous. Length about 
15cm. Maximum width about 13 cm. Petiole stout, prominent on 
the under surface of the leaf. Secondaries eight or nine subopposite 
to alternate pairs, diverging from the midrib at irregular intervals 
and varying angles ranging from 90° at the base to 20° in the tip of 
the leaf; they are stout and prominent, and relatively straight in 
their courses; the basals are short and camptodrome; the next pair 
likewise camptodrome, are short and give off on their outer sides 
three or four camptodrome tertiaries; the third pair are long and 
ascending and suggest incipient lateral primaries, giving off twoor 
three stout camptodrome branches from their outer sides; the remain- 
ing secondaries give off stout lateral branches two-thirds of the dis- 
tance above their bases. The internal tertiaries are relatively stout 
and well marked on the lower surface of the leaf; they are very 
closely spaced and largely percurrent at right angles to the seconda- 
ries; they frequently anastomose, especially toward the periphery 
of the leaf, in which region they are slightly more openly spaced. The 
nervilles are prevailingly at right angles to the tertiaries, are rather 
well marked, and anastomose to form a very fine mesh. 
The present species is exceedingly well marked and also exceed- 
ingly like the existing Central American species Coussapoa ruizit 
Klotsch and Coussapoa villosa Poeppig and Endlicher. It is also 
very similar to Coussapoa villosoides Berry* of the Miocene of
