It is true that some of these species also bear a very close resemblance to 
plants recorded from a somewhat lower horizon. Species of Tceniopteris are 
usually unsatisfactory as criteria of age owing to the close resemblance between 
leaves of this type from rocks ranging from rhaetic to wealden ; but the 
narrow type, T. Daintreei, is an uncommon form, which occurs also in India in 
strata included in the Rajmahal and in the Kota-maleri series ; that is, in 
beds usually regarded as liassic and lower oolite respectively. Lycopodites 
Victor ice is very similar to the plant named by Oldham and Morris Arau- 
carites gracilis from the Rajmahal Hills, and SpJienopteris Hislopi from the 
same beds may be identical with SpJienopteris ampla of Gippsland. 
The genus Thinnfeldia , to which I have referred a few of the Australian 
specimens, is in some forms characteristic of rhaetic strata, but the fragments 
from Gippsland do not exhibit much resemblance to the more typical older 
forms, and in themselves they do not afford an argument against a jurassic age. 
On the whole, it would seem probable that these fragmentary relics of a 
mesozoic vegetation may be regarded as representatives of a jurassic flora, 
approximately of the same age as the inferior oolite flora of England, or with 
that of the Rajmahal series of India.
