This species differs from all other true Chitons of New Zealand in 

 its finely sculptured, comparatively smooth surface, resembling in 

 this respect the t '. magnificat of South America. It is a well known 

 New Zealand form, and has also been reported fr-nn Port -Jack.-oii, 

 Australia, by . \ii-a-, under the name /"<">; but I have not been 

 able to confirm this by the compari-on nf -pecimens from the latter 

 locality, which may safely l>e omitted until authoritatively con- 

 firmed.
