under the name G. elegans, which, in the characters of the midrib 

 and nervation generally, offers a close comparison with the Indian 

 species under consideration. It is, however, impossible, on such 

 imperfect evidence, to arrive at any conclusion as to the identity of 

 these two fronds, and for the present G. elegans can hardly rank as 

 a well-defined species. With these species may be also compared 

 Feistruantel's G. gatigamopteroides (see p. 53) from New South 

 Wales. 



The Indian specimens figured by Feistmantel 1 as Sagenopteris (?) 

 Stoliczhma are undoubtedly Glossopteris fronds, and very possibly 

 leaves of G. decipiens. 



Glossopteris decipiens is known only from the Karharbari Series of 

 the Talchir division of India. 



Not represented in the British Museum collection.

 Suppl., p. 53, pi. xxxi, figs. 1, 3. 



Type. Nos. 5084 and 5086, Mus. Geol. Surv. India, Calcutta. 



Frond oblong-oval, with a long petiole. Midrib distinct in the 

 lower part of the frond, but evanescent above. Secondary nervation 

 arising at a sub-acute angle, forming somewhat broad, oblong 

 meshes. 



This frond is only known from the Karharbari Series in India. 

 Its chief distinguishing characters appear to be the long petiole, and 

 impersistent midrib. 



Not represented in the British Museum collection.
