Invasion Description

1st Record: 'Sandwich Islands'/HI/Pacific Ocean (Reeves 1859, cited by Carlton and Eldredge 2009)

'We suggest that this brackish-water jingle shell, although described from the Hawaiian Islands, is an early ship-fouling introduction from the Indo-West Pacific Ocean. Its specific geographic origin remains unknown at this time. It has not yet apparently been reported as a fossil in the Islands. It is unlikely to have been missed in collections of some two or three decades prior to the 1850s [for example, Conrad’s (1837), description of shallow-water endemic Hawaiian brackish water mytilids]. It may thus be another example of a species being first described from the site of introduction. Genetic studies of this species would be especially compelling.' (Carltton and Eldredge 2009)
