V. DECUSSATA. _Cha._ testa ovata, decussatim striata.

"Sæpe" and "minimus" are the sole printed additions.

Probably the _V. Phryne_ of the 'Systema' was designed by the following

unpublished description:--

CUN. VENOSUS. C. subcordatus lævis lateribus rugosis. Testa cinerea,

nuce coryli major, gibba, glabra, antice et postice transversim sulcata.

Margo exterius tantum denticulatus, non vero apex externus, aut margines

laterales.

The _V. macrodon_ answers fairly enough to this definition.
