Igdlokunguak, Greenland, except that the basal primary 
forks a considerable distance from its base. I was at first 
disposed to refer them to Aralia Towner? Lesq., particularly 
as Heer compared his leaves with that species and Les- 
quereux suggested * that the two were identical. 
While the occurrence of two such large-leaved species of 
Aralia in the Matawan formation may seem anomalous, 
especially as they had much in common, I fail to see their 
identity. Aralia Towner was a palmately five-lobed leaf with 
a decurrent base and obtuse lanceolate lobes. Arata Rav- 
nzana on the other hand was probably a six- or seven-lobed 
leaf of large size, for while in no case is the apex preserved, 
I cannot conceive that such a leaf as the discovered frag- 
ments evidently represent could have had an undivided 
terminal lobe. If they had, they would differ from all other 
species of Arafia in its size, and from lobed leaves in gen- 
eral. They would have had a lobe wider than long, with an 
area greater than the balance of the leaf, the deep lateral 
sinuses almost cutting it off from the rest of the blade. In 
the specimen figured at p/. 57, f. r (one fourth natural size) 
the midrib more than half way to the tip gives off a strong 
lateral branch which it seems reasonable to suppose formed 
the midrib of a lateral lobe. Furthermore, A. Ravniana 
differs from A. Townerz in having stouter primaries, nar- 
rower sinuses, more ovate lobes, the basal ones widely spread- 
ing, and the base but slightly or not at all decurrent. If we 
may judge from the obsolete venation, it was a more cori- 
aceous leaf.

It is easier perhaps to criticise others than to escape criti- 
cism oneself, at the same time in considering the leaves which 
seem referable to Araia in our collections from near Cliff- 
wood and in comparing them with the Raritan forms referred
