Description
The image displays an elongate-ovate, smooth, and highly glossy shell. It features a moderately tall, pointed spire and a long, narrow aperture that extends almost the full length of the body whorl. The columella is thickened and twisted at the base, exhibiting a distinct orange-brown color. The shell's surface is predominantly a pale brownish-cream to grayish-tan, adorned with irregular, wavy, darker brown axial streaks and blotches, particularly visible on the body whorl. The interior of the aperture also reflects the orange-brown hue of the columella.
