Procymbuliidae, 1913

This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family was originally called Procymbuliidae Tesch, 1913 and then called Peraclididae by Wenz in 1938.[2] The name Peraclidae takes precedence.

Peracle is the type genus of the family Peraclidae.

Description

The left-coiled shell resembles the shell of most snails. The columella is somewhat elongated into a curved rostrum. There is an operculum and a gill.

Species within the genus Peracle Forbes, 1844 include:

  • † Peracle charlotteae Janssen & Little, 2010[3]
  • Peracle depressa Meisenheimer, 1906 - Distribution: Cuba, Brazil, Argentina, Oceanic, Equatorial Atlantic.
  • Peracle diversa (Monterosato, 1875) - synonyms: Peracle apicifulva Meisenheimer, 1906,
  • Peracle bispinosa Pelseneer, 1888, Two-spine pteropod. Distribution: Florida, Bermuda, Cuba, Argentina, Mediterranean. Length: 4 mm.

gollark: I once made traffic lights which shot anything moving too fast with lasers, but didn't exempt lasers from being lased, that was fun.
gollark: > The frickin' laser beam fires a bolt of superheated plasma, a softnose laser, or some other handwavey science. This powerful projectile can deal incredible damage to mobs and blocks alike.So apparently it does lampshade it, yes.
gollark: Is that really a *wiki* though?
gollark: Well, apparently the wiki.cc.cc search doesn't work.
gollark: If science™ mattered lasers would be actual beams which travelled at light speed and without the weird range limits.
