1 Possibly this is the variety of T. punctata described as T. subcellifera by Dr. U. Schloembach in bis 

 'Eisenstein des mittl. Lias,' p. 548 (' Zeitschr. d. d. geol.Ges. in 1863,' Bnd. xv, Hft. 3). If this is the 

 case his name should of course be adopted, but as I have not seen either figures or specimens, I am not 

 quite certain if is identical.
