But these Rajmahal species approach on one hand pretty nearly the 

 Rhcetic Macrot. gigantea, Schenk,* on the other hand those forms from 

 the Kamthis which I have lately briefly described as Macrot. Feddeni 

 Fstm.,f and wbich are all to a certain degree related to that Permian 

 Taeniopt. abnormis, G-ubb., of which I have already spoken. 



These species are all based chiefly upon the different distances apart, 

 the formation, the direction, and the thickness, of the veins, and if we 

 compare all together, then we have the following table : — 



1. Macrotceniopteris danaeoides, McClelL, with the most distant veins, 

 nearly straight. 



2. Macrotaeniopteris gigantea, Schenk., and the Rajmahal species, 

 Macrot. lata, O. M. and Macrot. musaefolia, 0. M., with veins almost 

 equally distant. 



3. Macrot. Feddeni, Fstm., with pretty close veins, a little oblique. 



4. Taeniopt. (Macrotaeniopt) abnormis, Gatb., with very close and 

 almost straight veins. 



For us it is a great satisfaction to find the genus Macrotaeniopt eris 

 so frequently represented, as Mr. Oldham to the last maintained that 

 no Taeniopteris are in the Damudas,J and in a letter to Mr. "W. B. 

 Clarke, which this latter gentleman has published in his ' Remarks on the 

 Sedimentary formations in New South Wales,' 3rd Edition, 1875, p. 29, § 

 Mr. Oldham maintains that in the Panchet group also no Taeniopteris 

 has been found, although it occurs. 



Amongst all the numerous specimens not one occurred which showed 

 any trace of fructification, so that it cannot be decided with certainty 

 to which living genus the species should be referred, but as far as can be 

 judged from the form of the leaf and from the veins I would refer it to 

 some form of Acrostichum, for example, Acrosticlmm hybridum, Bory. 

 Its fossil allies have been already indicated. 



Maceot^istiopteeis sp. 



Another specimen of Macrotaeniopteris occurred ; but it unfortunately 

 is so badly preserved that it cannot be figured nor any exact descrip- 

 tion of it given. It is only a portion of a leaf- surface, no rhachis being 

 preserved.
