Identificaciones de snailboy

Part of a 55 yr old collection. Item used to help Cawthron Inst identify predators.
This one has been attacked by a weka, the snail's only non-introduced natural enemy. Typical bird and rat attack is executed at this point, which is the most vulnerable point for shell's occupant and most rewarding for attacker.

This is NOT the tagged sp Powelliphanta 'Lodestone' and appears to belong to the P hochstetteri aggregate.

Another pale shell form.

Thank you for the description of P. 'Lodestone'. These are from the same mountain but do not match the description provided below.

Typical examples on this end of the range [assuming Flora saddle may create an altitudinal hiatus] are quite pale and sparsely striated above, but usually have a band of fine striations on the underside which sometimes extend right into the umbilical area.
