Möller as intermediate between the Rhætic and Oolitic floras. A curious feature 
is that of the 9 identical species not less than 8 belong to the ferns, the remaining 
one being the cycadophyte Ptilophylluin pectinoides. Among the other Cycadophyta 
and Coniferce of Hope Bay, there are a few which show some resemblance to English 
Lower Oolite species, but not enough to warrant a specific identification. This ab- 
normal proportion of the number of identical Pteridophyta and Spermophyta may be 
quite accidental, but is certainly very strange, all the more so because the Spermo- 
phyta outnumber the Pteridophyta both in the Lower Oolite of England and in the 
plant-bearing beds of Hope Bay. The absence of the Ginkgoales in the Antarctic 
flora has some influence on this strange relation, but not enough to account for it. 
As will be seen next below, the proportion of both groups is just the reverse in 
relation to another of the more important Jurassic floras. 
The floras of the Upper Gondwanas of India are universally accepted as being 
of Jurassic age. Though they are held to belong to somewhat different horizons, 
ranging from the Liassic to the Lower Oolite, some species are common to them 
all, and the differences are on the whole not very great. For the purpose of a com- 
parison with the Hope Bay flora, it may be permissible to regard these Indian floras 
first as a whole. The species of the Antarctic flora enumerated below are found 
in one or more of the groups of the Upper Gondwanas of India. If the Ragava- 
puram shales and the plant-bearing beds of Sripermatur and Utatur are, with Feist- 
MANTEL (1879), regarded as contemporaneous and are provisionally designated the 
Madras Group, the distribution of the species on the different groups will be the 
following: 
Cladophlebis {Eboraciar) lobifolia (Phill.) — Jabalpur. 
Coniopteris i lobata (Oldh.) — Rajmahal. 
Otozamites Hislopi (Oldh.) — Madras, Jabalpur. 
» abbreviatus Feistm. — Rajmahal, Madras. 
Araucarites cutchcnsis Feistm. — Madras, Kach, Jabalpur. 
Pagiophylluin Feistmnnteli n. sp. [= Pachyphylliim peregrimtm FeiSTM., non (Lindl. 
& Hutt.)] — Madras. 
Elatocladus co 7 iferta (Oldh.) — Rajmahal, Madras. 
» jabalpurensis (Feistm.) — Madras, Jabalpur. 
It is curious that the number of identical Spermophyta is so much greater than 
that of the Pteridophyta^ the relation being the reverse of the one found in the 
comparison with the English Lower Oolite flora. In addition to these probably 
identical species, there are others which serve to accentuate the affinity of the Hope 
Bay flora to the floras of the Upper Gondwanas of India, by presenting a more or 
less marked resemblance to forms from that area. If, however, we consider only
