Taxonomy:
S. cylindrica has been used in the Palaeogene, but mostly for specimens markedly taller than in the original description so an alternative identification such as S. columella might be more appropriate
Distinguishing features: Squat, parallel sided, wide opening, almost square in profile, usually with weak flaring collar
