Varietal Cliaracters. — Smaller and more delicately sculptured than the type, 

 the longitudinal costge being finer and more numerous ; the spire is generally 

 shorter, and the mouth narroAver and longer in proportion. 



Dimensions. — L. 10 mm. B. 4 mm. 



Distribution. — Recent: Mediterranean — Naples, Taranto (Monterosato). 

 Madeira and the Canaries (M'Andrew). 



Fossil : Waltonian Crag : Little Oakley. 



Upper Miocene: Stazzano (Bellardi). Lower Pliocene: Savona. Upper 

 Pliocene : Biot, Altavilla. Pleistocene : Valle Biaia, near Pisa. 



Bemai'JtS. — The present shell appears to be a southern form, unrecorded, as far 

 as I know, from British seas. I have found several well-marked specimens at 

 Oakley, associated with the type form of H. septangular is. It was originally 

 described by Philippi as distinct, but has been regarded by later writers as a 

 variety of the latter species. The Marchese di Monterosato, however, still con- 

 siders it worthy of specific rank. Neither H. septangularis nor the present variety 

 has been previously reported from the Crag. 



A somewhat similar shell, from the Miocene of Northern Italy, has been 

 identified by Prof. Sacco with the var. A of Bellardi.
