Verconella koruahinensis n. sp. (Figs. 59 and 60).
Species of moderate size near V. adusta (Phil.). Only one specimen known. Fairly large, fusiform shell, with conical spire half the height of aperture and canal. Body-whorl with rounded shoulder-angle bearing rather distant rounded nodules present also on spire-whorls. Nodules regularly increasing and almost spinose on body-whorl; without the connecting carina present in adusta. Axial costae only faintly developed.
Aperture, columella, inner lip, and anterior canal as in adusta; columella broken below. Outer lip thin, not crenulate as in adusta, owing to finer sculpture. Posterior canal narrow, as shoulder of body-whorl is appressed towards suture. Suture appressed, somewhat deep; undulating on account of position immediately below nodular carina.
Ornamentation of numerous spiral lirae (very much finer than in adusta) with intervening still finer secondary threads, varying in number from 1 to 5—generally 1 on spire whorls and 4 or 5 on body-whorl.
Dimensions of holotype: Height (apex broken), 71.4 mm.; approximate breadth, 36.5 mm.
