abundant in the Karharbari beds of India and not very rare in South 
Africa or Brasil and Argentina. These circumstances, taken in con- 
nection with a presumptive relationship, based on vegetative characters, 
with the Neuropterids of the Northern Permo-Carboniferous flora, led 
Seward (1) to question whether the Gondwana plant is not really 
Cycadofilicate. Seward’s suggestion of a relationship of our plant with 
Cardiopterts, from the Northern Lower Carboniferous, is, in my 
judgment, well founded, as also is the suggested comparison with 
Stur’s Archacopteris Dawsont. The Gondwana plant is equally com- 
parable, I believe, with the frond from the Lower Carboniferous of 
the Eastern United States described by Meek (2) as Cyclopteris virgi 
niana, 
The leaf of the latter species, which has never been adequately 
illustrated, presents some points of striking similarity to Newropteri- 
dium Plantianum. 
Both types, it seems to me, are to be regarded as probably 
Cycadofilicate. 
The question ot the congenerity of the Triassic Crematopteris and 
the lower Gordwana Neuropleridium is one appearing to deserve 
careful consideration.
