Velutina prolongata
From Natural History of Southeast Alaska
Smooth velvet shell (Velutina prolongata): This species differs from Spiral velvet snail (Velutina velutina) by having a smoother shell, a more oblong, less round opening, and, when alive, a yellow-lined mantle. It is usually found on solitary Ascidians, such as the Corellidae Transparent tunicate (Corella willmeriana) and Disc-top tunicate (Chelyosoma productum). It has been found on Marine vomit (Didemnum vexillum), but was not observed feeding on it. In one case, a specimen was found that was overgrown by Marine vomit (Didemnum vexillum) to such an extent that it could no longer move.
