A REVIEW OP THE VOLUTIDAE 



Mlcrovoluta cuvierensls Plnlay 

 (Unfigured) 



1950 



Mlcrovoluta cuvierensls Finlay, Trans. New 

 Zeal. Inst., vol. 59, P- 242, I93O. 

 Powell, Shellfish of New Zeal., p. 8I, 

 sp. 1092, 1937. 



Alt. 6.5, dlam. 2.7 mm. 



Hab. New Zealand (Aupourian faunal prov- 

 ince in deep water). Type locality 38 

 fathoms off Cuvler Island. Also taken 

 In 10 fathoms off Snares Island and In 

 the Castlecllff Upper Pliocene deposit 

 of New Zealand. 



Shell differing at sight from bl~ 

 contca in its smooth appearance. Axials 

 and spirals are almost obsolete, but there 

 is generally a well-marked peripheral 

 groove on the body-whorl; the strong nod- 

 ules and spirals of biconlca are absent. 

 Shell more slender, with a leaner body 

 whorl. Sutural band quite different, in 

 biconlca there is a stout cord marginning 

 suture with a wide concave shoulder below 

 itj in cuvierensls there is a broad low 

 band with merely a narrow groove below it. 



This is quite distinct from bicon- 

 lca, one specimen of which was taken off 

 Cuvier Island with the holotype.
