Original description of Pugnellus orientalis by Lees, 1928:
- "Shell consists of five smooth whorls; the body-whorl, occupying about four-fifths of the total height, is strongly inflated; the remaining whorls form a low spire. 'Whorls slightly convex, and separated by a shallow suture; aperture narrow and elongate, the outer lip being extended to form a triangular wing attached to the spire between the last whorl-suture and the last but one. From this point of attachment the margin of the wing is approximately parallel to the side of the spire as far as a well-defined corner, below which the outer margin is parallel to the aperture. Lower extremity of outer lip folded upwards to form a hook-like projection, on the outer side of which the anterior siphon probably passes. The upper margin of the wing has a strong sigmoidal fold, the outer margin is sharp and folded outwards; inner lip smooth."
