Specific Characters.- — Shell fairly large, conical, oblique, smooth, whorls 5, the 

 last tumid, much the largest; spire short; suture slight; mouth large, semilunar; 

 xmibilicus more or less covered by the inner lip. 



Dimensions. — L. 25 — 30 mm. B. 20 — 22 mm. 



Distribution. — Not known living. 



Fossil : St. Erth. Coralline Crag : Ramsholt. Waltonian : 

 Little Oakley. Butleyan : Butley, otherwise not sufficiently worked out. 



Upper Pliocene (Scaldisien, Poederlien) : Belgium. Sicily — Altavilla. 



Remarks. — Wood has figured two specimens under this name, one in his 

 monograph of 1848 (op. cit.), showing the body-whorl as slightly depressed above, 

 and the umbilicus but partly covered by the callosity of the inner lip, the other, 

 which I distinguish by the varietal name Woodii (PI. LIV, figs. 9 and 10), that 

 represented in his 1st Supplement, 1872 (op. cit.), being more strictly conical in 

 form, with the outer lip not incurved. I have obtained both varieties at Oakley, 

 and one or the other may be found in our public collections at various localities 

 of the Red Crag. 



N. proxima is recorded by Belgian authorities from the Antwerp Crag, and 

 Seguenza includes it in his list of Upper Pliocene fossils from Altavilla, stating, 

 however, that the Sicilian shell is smaller than the Crag form. Whether these are 

 identical with ours I have no means of ascertaining. I am informed that 

 Seguenza's grand collections were destroyed by the tidal wave consequent on the 

 great earthquake of Messina. I was grieved to hear that his son, from whom I 

 received much kindness during my visit to Sicily, perished at the same time.
