There are two specimens in the Colonial Museum from Kapiti, Cook 

 Strait, which were considered by Captain Hutton to be Chiton sulcatus, 

 Quoy & Gaim. The specimens are not in a very good condition, one 

 is partly broken, and their original colour is gone. A close exami- 

 nation of them, as far as this was possible, proved them to be C. limans, 

 the scales being mucronated. These are the only specimens known to 

 have ])een found in New Zealand waters.
