20 MR. NEWELL ARBER ON THE CLARKE COLLECTION _[Feb. 1902, 
figures and descriptions with the Cambridge specimens, I regard 
them as identical. In the specimens from the Altai and Pechora- 
land, the nerves seem to be somewhat closer and finer, but in 
those from the Lower Tunguska the nervation agrees very exactly, 
while the contour of some of the leaves is almost identical. Another 
specimen, figured some years later by the same author! from the 
Altai, also agrees clesely. I propose, therefore, to adopt the name 
Noeggerathiopsis Goepperti (Schmal.) for the Cambridge specimens 
from Mulubimba. : 
As regards the identity of VV. Hislop: (Bunb.), the representative 
of this genus in India, South Africa, South America, and also pro- 
bably in Australia, with VV. Goeppertz,’ I have not been able to arrive 
at a definite conclusion. There is a great similarity of habit and 
detail between them. | 
Unfortunately, the specimens of this plant in the Clarke Collection 
do not add anything to our knowledge of the affinities of Noeggerathi- 
opsis. Feistmantel* has recently so judiciously summed up this 
question, that it needs no further discussion here. One of his 
conclusions, that the Noeggerathiopsidee may eventually be found 
to be the Indian and Australian representatives of the European and 
American Cordaitez is noteworthy. In many respects the Cambridge 
fossils present points of similarity to the leaves of Cordattes, 
especially in the nervation, which in some members of that group 
(the sub-group Dorycordaites) consists of nerves of the same size. 
It is interesting, in this connection, to recall the fact that Schmal- 
hausen * has recorded both NV. Goeppert:, and species of Cordaites, 
from the Permian of Russia.
