Natica, sp. 



G. 9580. Imperfect examples of a species having a thick 

 posterior callosity on the inner margin of the aperture, and the 

 umbilicus filled with callus ; allied to JY. solida, Sowerby. From 

 the Miocene, Upper Redcliffe beds, Eed Cliff, Eakaia river, 

 Canterbury, New Zealand. Sir James Hector Coll. 



G. 9607. Large species probably identical with the last- 

 mentioned, the posterior callosity being enormous, filling thei 

 umbilicus and extending anteriorly. Fi-om the Eocene, TrelissickJ 

 New Zealand. Sir James Hector Coll.

Shell naticiform ; umbilicus without a funiculus, open or closed 

 by callosity; aperture large; outer margin sinuous, produced at 

 the middle ; umbilical region limited by a spiral rib or limb more 

 or less developed ; columellar border curved, typically S-shaped. 



The writer cannot find that the name Ampullina (so commonly 

 applied to fossil naticiform shells of the Tertiary of North-Western 

 Europe) was properly established before Desor and Agassiz had 

 proposed the term Euspira. Defrance, who is generally credited 

 with having introduced Ampullina {op. supra cit.) does so in the 

 vernacular as "Ampulline," and even if that could be admitted 

 as proper establishment we are left in difficulty as to the meaning 

 of the term. "Ampulline" is not diagnosed, nor is it stated in 

 what way we are to distinguish it from Ampullaria as described by 

 Defrance.
