The holotype of Ondina hendersoni  (Figure 3a, b) matches the general features of the genus Ondina  , being however, larger with more globose whorls. The typical spiral lines of the genus are very numerous in the figured holotype and especially evident on the lower half of the teleoconch whorls.

This species was recorded from Texas by Odé (1994) as Amoura cf. hendersoni  but the drawing of the shell ( Odé 1994: 48, fig. 4) exhibits a slender shell, with few spiral lines above suture, which resembles O. stocki  (see below).
