Igdlokunguak, Greenland, except that the basal primary 

 forks a considerable distance from its base. I was at first 

 disposed to refer them \.o Aralta Tozuneri 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 TozvncriWiH^ a palmately five-lobed leaf with 

 a decurrent base and obtuse lanceolate lobes. Aralia Rav- 

 niana 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 Aralia 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 //. SJ,/. i (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. Toivneri 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 Aralia in our collections from near Cliff- 

 wood and in comparing them with the Raritan forms referred
