594 PLIOCENE MOTJ.USCA. 



Sprcijic CJi<ii'arfers. — Shell minute, turreted, sniootli ; wliorls 8, convex, the 

 last considerably enlarged, obtusely angulate at the periphery, about one-half the 

 total length and excavated at the base; spire elongate, gradually diminishing 

 upwards to a small, compressed and acute apex ; suture well marked ; mouth 

 short, ovate, acutely angulate above, rounded below ; outer lip expanded, gently 

 rounded. 



Dimriislons.- — L. 2*5 mm. B. 1 mm. 



Diatribntion. — Not known living. 

 Fosnl: St. Erth. 



Renin rlrs. — The specimen here figured was ol)tained by Mr. A. Bell at St. Erth 

 and described by him in 1893 as a new species. At first he referred it to the 

 Arlis of Loven,but it appeal's to belong rather to an allied genus, Hemhiclis, proposed 

 bv Prof. G. O. Sars for a small gr()U[) of Norwegian shells without spiral sculpture. 

 At present our fossil seems to be unique.

Sprrijic Cliiiracters. — Shell miiuite, smooth, delicate, elongato-conical ; whorls 

 7 — 8, l)ut little convex, the last less than half the total length : spire regularly 

 diminishing in size upwards; somewhat attenuate near the apex; apex acute; 

 suture well marked, Ijut not dec]); mouth small, angulate above, rounded below, 

 laterally expanded ; peristome continuous.

liciiKirlrs. — The specimen here figured belongs to the York Museum, having 

 been olttained from tlie Coralline Crag of Sutton. It bears the name of Alcania 

 {? Aiiis) siipniniftila. It does not agree with tliat species., however, either in form 

 or sculpture, the latter being distinctly striated s])irally. The nearest thing I can 

 find to it is the Aclis atteimans of Jeffreys — a Mediterranean species, to which I 

 refer it provisionally.
