Lianophycus polyfrons, gen. nov. 
(Plate I. Reduced one-half. ) 
The simulation in life we find both in the present world’ 
and in the ancient, in living forms and in extinct forms; 
in the water and on the land. Thus in Lianophycus poly- 
frons we have a form from the ancient carboniferous ocean, 
that did its mission, like the Lianos as climbing plants in 
the forests of South America. I therefore created this 
Genus. This plant we find in twisted stems, some of them 
very delicate, reaching over from more robust seaweeds 
to others and climbing about and having hold wherever 
possible to sustain itself with its numerous fronds, and em- 
bellish a marine forest. The many dark brown spots over- 
lapping each other in a squamous way, I could not but think 
that they have been marine foliage, because all the fucoid 
stems on that slab are of the same brown color, while the 
sandstone slab, on which I have it, is of a light ash- 
gray. The fronds were small but multitudinous, and grow- 
ing in agglomerated bunches. — Carboniferous Sandstone..

inner punctate. Cells subcircular consisting of long fibrous:
