description
DESCRIPTION Type B planispiral and partially immersed protoconch. Teleoconch of three flat whorls; sculpture consists of inconspicuous orthocline growth lines; sutures impressed. Last whorl angular; umbilicus small and narrow, aperture oval, outer lip missing.
discussion
REMARKS The shell is short and conical; all specimens have a type B protoconch with an arch-shaped suture (Peñas & Rolán 2010). The apex of the protoconch forms a concavity to the suture between protoconch and first teleoconch whorl, which is a feature, observed in some specimens with type B partially immersed protoconchs in the genus Eulimastoma. Nevertheless, the present specimen lacks other characters that could place it in the latter genus (inflated suprasutural band, sculpture of the base of the shell).
