Geinitz (Quadersandst., p. 158,) following Reviss, &o., identifies L. lens and Reichii, Romer, L. mrculari.t 

 and V. parva, Gein., with the present species; in most cases this would appear to be correct, but not being iu 

 possession of authentic specimens, or of the originals, it would be a vain task to speculate on this point.

It is scarcely necessary to add anything to the dcscrii^tion of this well known 

 species. The shell varies a little in form, but it is always more or less orbicular, 

 sometimes with an indication of a quadrangular shape. Some specimens are 

 much compressed, others somewhat convex, and these variations are equally 

 observable in ou.r Indian specimens as in the typical ones from Aachen, of which 

 I had very good examples for comparison, obtained from Dr. Bosquet. 



Localities. — East of Anapaudy, north of Serdamungalum, and near Olapaudy, 

 mostly in a brownish sandstone ; not rare. 



Formation. — Trichiuopoly group. In Europe the species appears to occur all 

 through the upper cretaceous (Plsener) beds of Germany.
