| In the genus Pseudodaphnella this is generally paucispiral and papilliform with more or less orthocline axial riblets and weak spiral threads. |
| Beu and Climo discussed the matter further in relation to the genus Danilia and confirmed that the Euchelus operculum is indeed paucispiral like that of Littorina. |
| The protoconch is paucispiral or multispiral, and is smooth except for a few axial riblets near the junction with the teleoconch. |
