Stromboidea
Original Description of Dimorphosoma kinclispira by Gardner, 1875, p. 396:
- "Shell elongated; apex obtuse; whorls 7 or 8, inflated and rounded, ornamented by numerous longitudinal oblique, flexuous ribs, extending to the sutures. the ribs vary in number and prominence, there being about twenty and fourteen respectively on the penultimate whorls of the two known specimens; they are crossed by numerous distinct, irregular raised spiral striae, which are seen with an inch power to be angulated. The upper side of the last whorl is destitute of ribs, but has a very salient median keel, and a second subordinate keel in front; one of the spiral lines between the keels is more distinct than the rest. THe canal appears to have been long; the margin of the outer lip in front of the wing is angulated; the wing is simple, strong and ridge-like, projected slightly downwards."
