Diagnosis
ReferenceDiagnosis
J.d.C. Sowerby 1827Ovate, elongated, pointed, smooth; volutions convex ; aperture elongated, pointed above, nearly half as long as the shell.
F. M'Coy 1844 (Macrocheilus curvilineus)Very elongate; volutions broad, slightly convex, obscurely striated ; spire twice the length of the aperture. This species has the body whorl very little larger than that which precedes it; the spire is very long, although of comparatively few turns, the width of each volution equalling the diameter of the shell at that part; the transverse stria; on the volutions are very oblique, and somewhat curved, whence the name. Length one inch five lines ; diameter seven lines.
