Colus

Colus (lat. colus, distaff) is a genus of sea snails, marine gastropod mollusks in the family Colidae, the true whelks and the like.

Evolution
Colus is related to the New Zealand genus Austrofusus.

Taxonomy
The name Colus is not available from Humphrey, 1797 (published in a work placed on the Official Index). Most recent authors use the name Colus Röding, 1798 for the genus instead of Sipho Bruguière, 1792. Iredale (1919b) mentioned: "This name cannot be defended by anyone" and was rejected by the ICZN (Op. 21). Also Tritonofusus Beck, 1874 cannot be used because of the rules of priority.
