apex. They form a wide angle with the axis, sometimes they are quite perpendi- 
cular to it. They are retreciated at the base, and are attached sometimes only 
by the very middle of the pinnule, sometimes by a somewhat broader base. The 
lamina is dissected in 4 — 6 obtuse lobes, which are divided to at least the half of 
the distance between the margin and the midrib, often to very near the midrib. 
The lobes are mostly entire; sometimes, however, they are sinuate or faintly crenate. 
The midrib of the pinnules is distinct; it gives off fine and indistinct branches, one 
to each lobe. There is no trace of a fructification to be seen in any of the spe- 
cimens. 
The resemblance of the Antarctic specimens to Oldham’S species is so great 
that there cannot be much doubt as to their specific identity. To judge from the 
illustrations in the “Palæontologia Indica”, the only difference appears to be that in 
the Indian specimens the pinnules are, on an average, a little longer. This is not
