APORRHAIS UTTINGKRIANUS. 435 



Remarks. — The Coralline Crag specimen from Boyton figured under this name 

 corresponds, with one from the Miocene of the Vienna basin given by Homes and 

 with a Pliocene fossil from the Rhone valley by Fontannes. It seems to be a 

 dwarf form of A. pes-pelicani dating back to the Miocene period, being also 

 reported by Prof. Sacco from deposits of that age at Cuneo in Piedmont and from 

 the Astian and Piacenzian of the Ligurian coast, ns well as from the Faluns of 

 Touraine by MM. Dollfus and Dautzenberg, and as recent by the same authority 

 from Roussillon. 



Prof. Sacco regards this variety as characteristic of somewhat deeper water 

 conditions than those of the type form.

Specific Characters. — Shell turreted, generally smaller than A. pes-pelicani ; spire 

 short and wide, conical, at the apex forming an angle of about 45°; whorls 7-8, the 

 upper ones rounded, the lower angnlated with fine or nearly obsolete denticula- 

 tion ; mouth oblique, ending in a narrow canal, turning to the left. 



Dimensions. — L. 25 — 33 mm. B. 8 — 12 mm. 



Distribution. — Not known living. 



Fossil : Scaldisien : Antwerp. 



Miocene: north Germany, Vienna basin, Italy (Tortoniano, Elveziano). 



Lower Pliocene : Biot, Piedmont, Tuscany. Rhone valley, Roussillon and 

 elsewhere in southern France. 



Upper Pliocene : Monte Mario, Bologna, Orciano, Altavilla, Caltabiano, Gerace. 



Pleistocene : Taranto, Castroreale, Gravina, Girgenti, Nizzeti. 



Remarks. — This species, only known as fossil and exceedingly abundant in the 

 Piacenziano of northern Italy, ranges from the Miocene to the Sicilian Pleistocene. 

 I have a small specimen in my collection from the Scaldisien of Antwerp which I
