diaphragms, although small, are not comparable in detailed structure 
with x\rber’s New Zealand sy)ecies, Phyllotheca nmmta,^^ unless it 
could be ])roved that these a])parent nodes of the branches differed 
from the nodes of the stem, to which x4rber's figured specimens seem 
to belong. 
Distfihulwn. Phyllotheca bidica Bunbury, has not before been 
recorded from Australian rocks. It is found in India in the Raniganj 
sub-stage of the Daniuda stage (Upper series of Lower (fondwana).

Observations. - From an examination of the type specimen in the 
xMuseum of the Geological Society of London, Prof. A. C. SewanP® 
was of the opinion that it is impossible to distinguish between P. 
indica and P. australis. So far as the present writer has been able to 
judge, from the Australian. exam])les and from the fuller drawings 
by Feistmantel of Phyllotheca indica, there are some notable points 
of difference between the two species, which were also remarked 
upon by Newell Arber.
