Vellicola sp. #13
 
Vellicola sp. #13
Maximum size:  7 mm.

Identification:  This species has a thin, straw-colored shell with only a few faint, spiral stria on its apex and base. The animal is translucent-cream decorated with clusters of white flecks and short, randomly distributed brown lines. Older animals tend to be darker. It may be distinguished from Vellicola muscarius and Vellicola sp. #15 by its thinner shell and lack of prominent apical and basal striae.

Natural history:  Vellicola sp. #13 is a moderately common species found in rocky habitats from < 1 to 9 m (< 3 to 30 ft). It occurs at moderately protected to highly exposed sites and lays a spherical, cream egg mass that hatches in two to three days in the laboratory.

Distribution:  Big Island, Maui, Oahu, Kauai and French Frigate Shoals: widely distributed in the western & central Pacific.

Taxonomic notes:  Shells are present in various mixed lots at the Bishop Museum.
