fronds. He could assure Mr. Edwards that in India the dis- 

 covery of petrified remains of these plants, which Avould give 

 some insight into the structure, had long been desired ; but the 

 search had, so far, been without success, in those beds which 

 yielded Glossopteris. 



Mr. Thomas thanked the Fellows for their recejDtion of his 

 paper, and expressed the opinion that it might prove possible to 

 obtain cuticular preparations from some of the specimens of 

 Numimil ospermum figured by Dr. Walkom, although in the case 

 of Ottokaria the plant-tissue had undergone a more complete 

 change, and little trace of the outside surface was left. In reply 

 to Dr. Da vies, he said that the seeds which Ottolxciria perhaps 

 produced might jDOSsibly have been similar in form to those 

 described as Nummul.ospermum\ but the two structures differed 

 considerably in size. He thought that knowledge of both forms 

 was still so incomplete as to render any conclusions regarding their 

 relation to Glossopteris xevy speculative. The main value of these 

 communications was to draw attention to the various reproductive 

 structures of doubtful affinities found with the Glossopteris flora, 

 in the hope that further work and collections would show whether 

 they belonged to Glossopteris, Gangamopferis, or to one of the 

 other genera in this flora.
