described species. Remains are fragmentary, but indicate a 
simple ovate-lanceolate leaf 7-10 cm. long by about 2.25 
cm. wide, with ascending eamptodrome secondaries and 
transverse tertiaries.

The Cliffwood forms are identical with the smaller of 
Lesquereux’s leaves. Recorded by Hollick from the Ma- 
tawan formation; not found by me. 
Pauiurus Mill. Gard. Dict., ed. 7. 1759. 
There are only two existing species, one confined to 
southern China and Japan, and the other to southern Europe 
and western Asia. The fossil species are numerous, some 
sixteen occurring on this continent; it is pertinent to remark, 
however, that in the absence of fruit Palurus is practically 
indistinguishable from Zizyphus or Ceanothus.

PALIURUS INTEGRIFOLIUS Hollick (?). 
Patliurus integrifolius Hollick, Bull. Torrey Club, 21: 57.

This reference of a fragment from near Cliffwood was only 
provisional. The specimen represents the basal fragment of 
a leaf which is rather large for Paliwrus and lacks the lat- 
eral branches of the primaries which ought to be present in 
the left hand portion of the specimen. It might well represent 
the basal portion of some of the leaves from the Raritan 
formation which Newberry referred to Crss7tes formosus Heer. 
Not found by me.
