Stromboidea
Original Description of Pugnellus goldmani by Gardner, 1916, p. 469:
- "Shell large for the genus and relatively thin, quite highly polished; outline exclusive of the alate outer lip, broadly and symmetrically lenticular, the maximum diameter falling near the median horizontal; whorls five in number, very closely appressed, regularly and rather rapidly increasing in size, those of the spire trapezoidal in outline, not constricted at the sutures so that the sides of the spire converge evenly and uninterrupted to the obtuse apex at an angle of approximately 35°; body whorl smoothly and gently rounded; external surface smooth, excepting for two or three incipient axial undulations upon the periphery of the final half turn, and for the faint incremental striations; sutures very closely appressed and indistinct; outline of aperture rudely and somewhat obliquely rectangular; outer lip alate, produced backward upon the penultima, thickened marginally, acutely angulated posteriorly at approximately 90°; labium oblique to feebly convex, roughly parallel to the lateral margin of the labrum; parietal wall free from wash; anterior extremity imperfect."
