Description. — Crassipaucicostate, with nearly quadrate whorls, periphery sub- 

 tabulate. 



Distinction. — From G. toar dense, the stouter whorls, broader periphery, coarser 

 costation.

173 (pars). 

 1902. — Janensch, Abh. Geol. Spez-Karte Elsass-Lothr., 



N. F., Heft v, PL iii, fig. 2. 



Distinction. — A less robust form than G. audax, with smaller, more numerous, 

 costas, and a narrow though flattish periphery. 



Remarks. — Beyond the diameter of the specimen depicted in Plate XXVIII, 

 figs. 7, 8, the periphery becomes more and more fastigate, though the ribs tend to 

 gain more of the distant character of those in G. audax. 



The largest specimens which I have obtained are, from Coaley Wood, 140 mm. 

 in diameter, from Wotton-under-Edge, 127 mm. in diameter.

 1902. penesteiatultjm, Emend. Amm. Nom., p. 3. 



Description. — Subparvicostate, periphery fastigate. 



Distinction. — From G. striatulum, coarser, less numerous costse.

 not necessarily of G. striatulum.
