Stromboidea
Original description of Pugnellus tumidus by Gabb, 1860:
- "Shell heavy, scalariform, spire elevated, five whorls, which are angular at the upper part, and marked by a series of small nodes on the angle; body whorl large, mouth expanded, superior sinus very deep, outer lip very much thickened, especially the extreme outer portion or callosity, which is nearly as thick as long. The thickening of the superior and lateral edges of the outer lip, produces a deep fosset on the posterior portion of the body whorl, immediately behind the expansion of the lip; the inner lip is reflected over a portion of the spire; canal long and curved anteriorly."
