 logle, 1883, p. 607. 



Genotype: Valuta murtcina Lamarck (Eocene, 

 common to the Anglo- Paris Ian basin).

p. 100, April, 1906 (figured pi, 12, 

 figs, 1 and l). 



Alt, 65 mm, 



Hab. Apparently from Grignon, Eocene of 

 France . 



"Shell nearly fusiform, the base 

 narrow and smooth; the upper part with lon- 

 gitudinal, subcostated, spinous plaits; 

 inner lip thickened, the last plait on the 

 pillar very thick, and separated from the 

 others, which are slender and nearly obso- 

 lete, by a deep groove." 



R. Bullen Newton states that the 

 other species of this genus are very numer- 

 ous both In the London Clay and in the 

 Calcaire irossler of Grignon. He also fig- 

 ures in his paper another species Voluti- 

 lithes pertnsa Swalnson (both copies of 

 Swainson 's figures), which in turn is iden- 

 tical v±th Voluta costata Sowerby (see "Min- 

 eral Conchology" 1821, vol. Ill, pi. ccxc, 

 figs, 2, 4).
