specimens belong to the same group. In common with the 

 Indian species, the frond is bipinmt t ••. the pinuular attach- 

 ment is similar, the pinnules have a tendency to become 

 more obliquely inclined, margins sinuate or entire, never 

 denticulate. There is also a tendency in this fern for the 

 pinnules to be more closely set than in typical C. Roijlei, 1 

 The venation is very close to that of C. Roylei, but the 

 median nerve is relatively strong, secondaries acute, fre- 

 quently forking twiee. 



The Indian species is that originally described as Pecop- 

 teris LhuUeutum, lioyle, and removed to Alcthoptevis by 

 Schimper and Feistmantel. Alcthopteris Undleyana (?) 

 has been described from Mount Ksk in Queensland (Lower 

 Mesozoic) by Mr. Ktheridge. As will be seen by the figure 

 in the Queensland form, the pinnules are more elongate 

 and more acute than our species, and I have little doubt 

 that the two forms will be found to be different, on the 

 examination of larger series. Mr. Shirley's species from 

 Denmark Hill, Ipswich Coal Measures (Jurassic), is also 

 apparently different* 



In India Cladophlebis Roijlei is directly associated with 

 the Lower Gondwana Glossopteris Flora and also with 

 Si-It izoucuiui iimiriicancnsis, Feist m. It occurs in the 

 Raniganj Group, the upper portion of the Damudas. In 

 New South Wales no fossils of this type have been to the 

 present recorded from the Newcastle or Upper Coal 

 Measures, but I have recently seen a similar fern from the 

 Permo-Carboniferous Coal Measures of the Dawson River, 

 Queensland.
