Comentários:

(Wollaston, 1878): “This is unquestionably the most remarkable addition to the living Pulmoniferous Gastropods of St. Helena which we made during our late six months’ sojourn in that island.

It was first obtained by Mrs. Wollaston (and subsequently by myself and Mr. P. Whitehead in the same locality) in a damp and precipitous, but practically dried-up, watercourse issuing from the northern flanks of the great central ridge, about midway between Action and Diana’s Peak; but as the specimens were invariably dead and mutilated (though, at the same time, recent and highly coloured), it was evident to me that they had been washed into that situation by the winter floods, and that their real home was in the densely wooded region immediately above the spot where we found them.“
