Original description of Strombus dodoneus by Gardner, 1947:
- "Shell rather small for the genus, heavy, ovate-conic. Spire rather low. Nuclear whorls small, smooth, highly polished when perfectly preserved, acutely tapering, 4 to 5 in number; initial half turn slightly bulbous the 4 succeeding volutions rounded, trapezoidal, and increasing in size and inflation with a moderate degree of rapidity. Line between conch and protoconch marked by a slight thickening of the shell. Adult conch 9 or 10 times coiled. Earliest sculpture feeble and irregular, but before the end of the second conchal whorl there is a well-established ornamentation of approximately 22 sharply rounded axial costae, equisized except for. an occasional varix, equispaced, and uniform in prominence from suture to suture; spiral sculpture a little later in development and less uniform, usually about 12 low, flat, crowded lirae to a turn in the adolescent shell. First 4 to 6 whorls of conch laterally compressed with a tendency toward a peripheral bulge and regularly increasing in size; fifth or sixth whorl marked by abrupt development of an obtuse shoulder and by increased rapidity in growth. Sculpture much more variable after initiation of shoulder. Costals rapidly evanescing behind the periphery, less rapidly in front of it, and becoming gradually transformed into peripheral tubercles and on the body whorl into obtuse spines, of which the last 2 before the terminal tubercle are usually the most prominent; number of axial protuberances decreasing from 22 on the early whorls of the conch to about 9 on the body. Spirals irregular, varying in number and character, usually 7 to 9 sharp, V-shaped elevations upon the shoulders of the whorls with intercalated lirae or finer ridges, all of them finely crenulated in many individuals by the incrementals; sculpture in front of the periphery generally absent or concealed by the succeeding volution; spiral sculpture on body whorl unevenly developed, the primaries in the most strongly sculptured forms numbering 20 to 25, !irate or more frequently V-shaped, either low and rather wide or high, sharp, and narrow; intercalaries fortuitous; spirals commonly obsolete over the posterior two-thirds of the body, especially in the earlier half, strongest and most persistent near the anterior canal; siphonal fasciole obscurely lirate. Suture lines distinct, impressed, varying in the degree of appression, sometimes placed well in front of the peripheral tubercles or quite as often closely appressed to the summit of the tubercles on the shoulder of the preceding whorl and deeply sinuated by them. Aperture moderately wide, the margins subparallel. Outer lip thickened in the adult, irregularly lirate within, flaring away from the aperture, obtusely angulated at the shoulder, obliquely retreating before and behind it; basal constriction broad and not very deep. Labrum produced backward but not more than halfway across to the suture line. Posterior commissure obscurely sulcate. Labium straight, simple. Body callus extensive, moderately heavy. Siphonal fasciole well differentiated. Anterior canal recurved, broadly emarginate. Umbilicus closed by the reflected callus of the inner lip."
