The shell at this stage appeared brownish and translucent, and measured around 600-800 μm in length. The shell beak was relatively less elongated compared to the earlier stage. A few beige-white spots were present on the body whorl. The columella and siphonal canal were well developed, and the operculum neatly fit in the columella opening.The foot was whitish and fairly muscular.
