Bulla peasiana Pilsbry, 1893

Maximum size: 39 mm
(extrapolated from shell length).
Identification:
This species has a brown shell densely spotted with cream. Areas of
smaller and larger cream spots may form broad axial bands in some
cases. The animal is cream frosted with brown and flecked with white.
It may
be distinguished from Bulla vernicosa
by its slenderer, more lightly calcified shell as well as by the broad,
translucent areas around its eye spots.
Natural history:
Bulla peasiana is
a moderately rare species found in mixed habitats at moderately exposed
to highly exposed sites. Mature animals occur in depths of 5-15 m
(16-52 ft).
However, dead shells in sand samples suggest that it is more common in Halimeda kanaloana beds at greater
depths. Dredged shells
from the Bishop Museum extend the depth range to at least 73 m (239
ft). It is nocturnal and buries itself in sand during the day.
Distribution:
Big Island, Maui, Oahu, Kauai, French Frigate Shoals and Midway.
Taxonomic notes:
Kay, 1979 listed this species as a synonym of Bulla vernicosa but it is now
considered distinct (Malaquias & Reid, 2008). The photo in Kay,
1979 labeled Bulla vernicosa
is actually of this species. If was first reported from Hawaii in
Pease, 1860 (as Bulla marmorea).
