Diagnosis
ReferenceDiagnosis
J. Gründel and A. Nützel 2012The shell is egg-shaped and broadly oval. The spire is somewhat (e.g. in type genus) to distinctly elevated. The whorls embrace distinctly below the suture. A ramp is absent in modern Bullina but present in some fossil genera. The ramp may be demarcated from whorl face by a spiral furrow. The whorls are more or less convex. The teleoconch of the modern type genus Bullina and most fossil representatives is covered with spiral grooves. Spiral grooves are at least present on the base. The spiral grooves are separated in somewhat displaced portions (punctured) by strengthened growth lines. The aperture is elongated, drop-shaped, widened and rounded anteriorly and acute posteriorly; it may have a weak anterior outlet and lacks columellar folds. The parietal lip is convex, the columellar lip straight. The outer lip is convex. The inner lip may be somewhat broadened or forms a ledge which covers the umbilicus. We are not aware of report of the protoconch of the modern genus Bullina. Jurassic representatives have protoconchs which are mostly coaxial and rarely medioaxial. They are sharply demarcated from the teleoconch.
