that is similar in its markings and tubercles to Lamellaria sp. #1.
shell has a noticeably higher apex than the shell of that species. It
also differs from it in its soft (almost gelatinous)
texture and in having a foot that extends well behind the margin of the
mantle when it crawls. (Note 1)
is known from at least three animals found in Halimeda kanaloana
beds at 6-9 m (20-30 ft). It sometimes jerks rhythmically while crawling.
recorded in Hawaii from Maalaea Bay, Maui by PF on May 5, 2008.
Considering the differences in shell and texture there's some question
whether it will ultimately be placed in Lamellaria.

Observations and comments:
1: The 2008 animal died before it could
be photographed. When found, we thought it was a variant of Lamellaria sp. #1 but the shell
proved to be different when extracted. The size, general color,
texture and habitat of the 2014 animal match our recollection of the
previous one. However, it will take extraction of another shell to make
the match completely certain.
