Taxonomy

The history of the name Nassa is rather confused, because the name was allocated twice:

  • Nassa Röding, 1798 for mainly muricid species with the type species : Nassa picta Röding, 1798 (= Nassa serta (Bruguière, 1798).
  • Nassa Lamarck, 1799 : established for the species Buccinum mutabile Linnaeus, 1758, which is now classified as a synonym of Nassarius Duméril, 1805 in the family Nassariidae.

In the 19th and much of the 20th century, all species that were added to the genus Nassa were Nassa mud snails belonging to the family Nassariidae. After the rediscovery of Röding's catalogue of his collection Museum Boltenianum sive catalogus cimeliorum e tribus regnis naturæ quæ olim collegerat Joa. Fried Bolten, M. D. p. d. per XL. annos proto physicus Hamburgensis. Pars secunda continens conchylia sive testacea univalvia, bivalvia & multivalvia, the muricid genus Nassa Röding, 1798 was given priority over the genus Nassa named by Lamarck.

Nassa Lamarck was then synonymized with its oldest synonym Nassarius Duméril, 1806 by a ruling of the ICZN Op. 96, Direction 48 (21 Nov 1956)[2] and then to Nassarius (Sphaeronassa) Locard, 1886.[3]

Description

(Described as Iopas) The shell is ovate and rugose. The body whorl is large. The spire is acuminate. The aperture is moderate, emarginate and channelled in front. The inner lip is covered with a thin enamel, and with a prominent plait-like callosity at the hind part. The columella is rounded and subtruncate anteriorly. The outer lip is sinuous and crenate internally. [4]
