sinistral

At the beginning of the last decade it was not uncommon for Harte to be praised as a sinistral David Beckham.

The same, mutatis mutandis, may occur in sinistral shells.

Shell helicoidally coiled, dextral or sinistral, the last whorl generally uncoiled.

This is carried outward in a sinistral spiral to the noded shoulder.

There are, for instance, nearly half a score of subgenera of Helix whose headquarters are Chinese, while among these, forms with sinistral shells are relatively common.
