Specific Characters. — Shell large, strong, subulate; whorls nearly flat, regu- 

 larly diminishing in size upwards ; coarsely ornamented by rather fine, rounded 

 spiral ridges, varying in number and thickness; spire slender, elongate; suture 

 slight ; base angular. 



Dimensions. — L. 80 — 100 mm. B. 15 — 25 mm. 



Distribution. — Not known living. 



Fossil: Coralline Crag: Sutton. Waltonian : Little Oakley. 

 Newbournian : Waldringfield. 



Miocene: northern Italy (Elveziano). 



Lower Pliocene : northern Italy, many localities, abundant in places. Biot. 



Upper Pliocene : Asti, Bologna, Monte Mario, Legoli, Siena, Caltabiano. 



Pleistocene : Valle Biaia. Monte Pellegrino. Naso, Barcellona-Castroreale. 



Remarks. — Turritella tornata is a characteristic species of the Italian Pliocene ; 

 it was in existence in southern seas in Miocene times, where it lingered on to the 

 Pleistocene period. The Crag fossil here figured belongs to the Ipswich Museum, 

 and was obtained from the Coralline Crag of Sutton. I have some imperfect 

 specimens of it from Oakley and there is another from Waldringfield in Major 

 Moore's collection which seems to be the same, though larger in size — 25 mm. 

 in breadth.
