and Rliiptozamites to form a separate section of plants, which eventually may 
represent, in Asia and Australia, the Cordaitese of Europe and America ; but 
as long as the real attachment of the leaves and leaflets, the inflorescence, and 
fructification are unknown, it is as correct to place the Noggerathiopsideac 
with the Cycadeaceae as with the Cordaitese. But one question would 
remain — which of the two names, Rliiptozamites or Nagger a i hiops is, should 
he retained in case such a transfer from the Cycadeaceae to the Cordaiteae 
should he effected? Not regarding the question of priority — which it is 
rather difficult to decide, as both names appear to have been given simul- 
taneously, but independently — it appears to me that Noggerathiopsis is the 
better name. Both the Indian and Siberian leaves were formerly called 
Noggerathia. Recognising that they do not belong to Noggerathia, I called 
the Indian and Australian leaves Noggerathiopsis, which thus reminds one of 
the previous name, without having special reference to any family. Prof. 
Schmalhausen, however, being at first convinced of the Cycadaceous nature 
of his leaves, called them Rliiptozamites, a name which has no reference to 
the previous denomination, hut which is a closely defined name, indicating 
not only the class Cycadeaceae, but also the family Zamiese, in which the 
genus was intended to be placed. If now, as Mr. Schmalhausen thinks, 
these leaves would rather belong to the Cordaiteae, then it would follow that 
Rliiptozamites would rather be a misplaced name in that family, which pro- 
bably is more allied to the Coniferao. Thus I think it is much more natural 
to retain the name Noggerathiopsis, in the family N oggerathiopsidete, 
including Rliiptozamites, and being perhaps more closely allied with Cyca- 
deaceae. 
Erom Australia there are several species of Noggerathiopsis, Eeistm. 
known, and this in the Lower Coal Measures (Carboniferous) and Upper Coal 
Measures (Permian ?). In India the same genus appears at first in the 
Talcliir Shales (Permian), and passes up into the highest Damuda beds, 
Raniganj -ICamthi Group (Trias).
