Unidentified Pleurobranchid #3
|Maximum size: about 28 mm.|
is a pale-peach animal that may appear white in ambient light. It has a
weakly pustulate notum and may be distinguished from Berthella pellucida by its lack of translucent-white reticulation. It has prominent acid glands in its notum.
pleurobranchid #3 is
known from two animals found in caves at 6-8 m (20-25 ft).
Perhaps, this is a third Berthellina sp.? (Note 1) Alternatively, there's a chance that it might turn out to be a very pale Berthelina delicata. It was first recorded in Hawaii at "Kei Kei Caverns," Kohala Coast, Big
Island by David Rafalovich on Aug. 1, 2013.

Observations and comments:
1: The pleurobranchid shells listed as "un. sp. #2" could turn out to be from this species. However, with multiple candidates, that will require further work for confirmation.
