More Hawaian shells

[paul monfils]

1  Pecten (Haumea) juddi

2-3  Isognomon californicum

4-5  Definitely not a Glycymeris!  I was misled by the external view, which made the shell look round in outline and bilaterally symmetrical. The interior view clearly shows that it is neither.  This is a Ctena species, in the family Lucinidae, probably Ctena bella.

6  Pretty beach worn, but based on the general shape, low spire, and suggestion of nodularity on the shoulder, and assuming it's a mature shell, not a juvenile of a larger species, and considering what is found in Hawaii, my best guess would be Conus abbreviatus.

7  Yes, looks to me like another Hipponix pilosus. When alive these are covered with a very dense bristly periostracum, hence the name "pilosus", meaning "hairy".  <span class="petit">--Last edited by Paul Monfils on 2010-04-19 00:50:25 --</span>
