makes it impossible to determine the character of the nucleus, I feel 
that the most probable relationship of the type is with the Caricel- 
ling. The presence in the Chilean tertiaries of what seems like a 
more normal relative in Voluta alta Sowerby is also significant.

This genus is the degenerate descendant in one line, as Maculo- 
peplum is a normal descendant in another, from the Eocene Cart- 
cella. Its most prominent feature is the enfeebled plaits of the 
pillar, usually of diminished number as well as size, its thin shell 
and prominent caricella-nucleus. The absence of the radula it 
shares with Maculopeplum, though Halia, evidently a close relative, 
and even more degenerate as regards the shell, has retained the 
radula. 
V olutifusus Conrad, founded on V. mutabilis, to which he after- 
ward added V. dubia, is an absolute synonym of Aurinia.
