to this genus by Newberry, we are struck with the range of 
variability, not only within each species as defined by him, 
but in the whole group, and the thought forces itself upon us 
that perhaps it would be an advantage to cut down the total 
number of species. Newberry has described seven species 
from the Woodbridge horizon alone and only one from the 
higher beds at South Amboy. The occurrence of a variety 
of Aralia-like leaves in the Matawan shows that the imper- 
fection of the record is probably responsible for their absence 
in the intervening beds: and it seems rather incredible that 
each form represents an ancient species that flourished on the 
New Jersey coast in Cretaceous days. 
The leaves before us, while not uniform, seem to more 
nearly represent Avalia palmata than any other known form. 
Our “7. 5 may be compared with Newberry’s 7 6. While it 
is about one sixth smaller, other fragments from Cliffwood 
indicate a somewhat larger size; the lobes are a trifle more 
slender and the main sinuses somewhat deeper. The lower 
margins were sometimes undulate and the latero-basal lobes 
short. The lobation was, however, somewhat variable, as it 
was also in Newberry’s leaves. Our / 6 might be compared 
with a variety of forms, such as Ficus (?) Alaskana Newb. 
(Later Ext. Fl. ff. 57. f. 2) and Hedera obligua Newb. or 
Hedera primordialis Newb. of the Amboy Clays. It has 
the secondaries straighter than is usually the case in this 
genus; in its tertiary venation it agrees with Newberry’s # 3 
of Arata paimata. The secondaries were distant and were 
joined at their tip by widely arching loops. 
Other species with which our leaves may be compared are 
Cissites ingens Lesq. and Liguidambar integrifolium Lesq. 
(Cret. and Tert. Fl. 7. 74. f. 3).
