Diagnosis
ReferenceDiagnosis
E. L. Packard 1922Shell medium sized, spire high; whorls six or seven; spire whorls
convex, regularly curved above and below; suture rather shallow; body whorl large, probably with a short canal; outer lip broadly expanded; marginb concave below, terminating in a blunt point at the end of a ridge which originates at the middle of the body whorl. Upper margin of lip extends in an even concave curve nearly to the top of the spire; outer posterior margin of the lip is thickened along the margin of the spire; Whorls of the spire ornamented by 8 to 12 transverse ribs and by fine spiral lines; these ribs extend only to the body whorl,
which appears to be unornanmented except for the angulation that terminates at the apex of the lip. Length of type, 28+ mm.; diameter of body whorl, 15 mm.; length from the middle of the body whorl, 18 mm.
L. R. Saul 1998An Alarimella with the outer lip expanded into a broad triangle.
