Volvatella pyriformis
Pease, 1868
 
no photo
available

Maximum size:  11 mm (Kay, 1979).

Identification:  This species has a thin, transparent shell that narrows into a spout posteriorly. The animal is pale orange flecked with darker orange. (Kay, 1979)

Natural history:  We've never found Volvatella pyriformis. Kay (1979) reports it from algal mats on solution benches and from the green alga Caulerpa.

Distribution:  Oahu.

Taxonomic notes:  It was first reported from Hawaii in Kay, 1961 (as Arthressa evansi). The shell on page 64 of Kay & Schoenberg-Dole, 1991 seems more strongly inflated with a more constricted apex than the shell of the live animal on page 65 suggesting that it may be from Volvatella vigourouxi, instead (or that it became greatly distorted, with drying). The drawing from the original Tahiti description of V. pyriformis can be seen on the Sea Slug Forum.
