Cystiscus sandwicensis (Pease, 1860)
 
Cystiscus sandwicensis
Maximum size:  2.5 mm shell length (Kay, 1979).

Identification:  This is a tiny species with a transparent shell and obscure sutures. Variable orange and brown reticulations on a white ground show through the shell. The body and foot are translucent-white with orange patches and opaque-white bands. The eyes are black.

Natural history:  Cystiscus sandwicensis is a common species found in rocky habitats at moderately protected to moderately exposed sites.

Distribution:  Big Island, Maui and Oahu: widely distributed in the Indo-Pacific.

Taxonomic notes:  It's listed in Kay, 1979, as Granula sandwicensis. There's some chance that very pale animals might be a distinct species.
