Description
The living animal of Corona pfeifferi has coarse, orange tubercles on a whitish skin. The tentacles are greyish, with a blue hue near the tips.
The shell has 8 whorls.
The height of the shell of the type specimen is 59 mm. The width of the shell of the type specimen is 26 mm. The height of the aperture of the type specimen is 25 mm.
Reproductive system: The penis is proximally slender and subcylindrical, constricted at the base; median part is swollen, pear-shaped, tapering towards the distal part which is subcylindrical again. Transition to the epiphallus with a kink, thereafter gradually tapering; twisted. Vas deferens is adhering to and partially inside the penial complex. Flagellum has ca. 1/5 the total length of the penial complex. Internal structure of penial complex is with longitudinal folds in proximal part of penis, changing into a dense tubular network and a widened lumen in the distal part of the penis. The epiphallus has 3-4 longitudinal folds proximally, transversing into anatosmosing folds more distally. In the specimen dissected, a chitinous spermatophore was being formed with the shape of flagellum and epiphallus, its initial stage inside the flagellum and extending to the distal part of the penis.
