PARTE IX. 



Riguardo ai Cyrsotrema del Bartonìano di Gassino, cioè: C. gassinense , C. eoartricidatum, 

 C. Rovasendae e C. eovaricosiim , debbo aggiungere come e.<si costituiscano 

 quasi un passaggio nlle Crassiscala DE BOURY, ma non sembrami clie pos- 

 sansi coiLsiderare come vere Crassiscala ; se ne potrebbe forse costituire un 

 nuovo sottogenere Cyrsocrassiscala SACCO 1891. 



Eemiacirsa lanceolata (Br.) var. dertoBrocchii SACC. — Distinguitur a var. Braccìni Pant. 

 anfractibus ad snturam non depressis. — Tortoniano : Stazzano (rara). 



E, lanceolata (Br.) var. pUoBrocchii SACC. — Distinguitur a var. Brocchii PANT., suturi» 

 profundis; anfractibus ad suturam non depressis, costis longitudinalibus nu- 

 merosioribus. — Piacenziano: Bacedasco nel Piacentino (rara). 



E. lanceolata (Br.) var. costulata (BORS.), 1823 — Tu7->-iteUa costulata BORS. — BORSON, 

 Oritt. piem. , p. 181 (313). — Astigiana. — Dall'esame dell'esemplare tipico 

 risultami essere afflnissima questa forma alla var. prys7natica.
