Comparison of specimens suggests that lincolniensis was 
based on a juvenile of the shell simultaneously named patruelis 
by Angas. The peculiar sculpture and form is the same, and the 
young shells of patruelis are inseparable from the so-called 
lincolniensis, 
Cox wrote ^'Two specimens from Flinders Island are of a 
smaller variety; but there can be no doubt as to specific identity, 
for one shows very plainly, not merely, in addition to similarity 
of sculpturing, etc., the pale patch on the lower surface, but also 
the spiral band below the suture.” 
Specimens from Thistle Island also belong to this species 
but whether subspecific differentiation has taken place cannot be 
determined from the material available.

Although Tate’s induta has been placed as a synonym the 
description does not seem to apply to this shell at all, so the 
type should be re-examined, Tate’s name is invalid, so a new 
name must be provided if the species needs reinstatement.
