r>ength ] 8 mm., breadth 9 mm. 



Station. ^On the under side or at the edge of insertion in the 

 sand of small smooth stones, in sheltered pools, at low tide. 



Habitat. — ^Lord Howe Island. 



Remarks. — This delicately tinted shell is rather common in the 

 pcjols of the fringing reef on the eastern side of the Island, whei'e 

 a quantity of smooth basalt shingle and waterworn coral rock has 

 accumulated. The animal is alert (as compared with other mem- 

 bers of the genus), and upon being removed from its position or 

 disturbed, quickly contracts and drops off, in this respect 

 resembling the Ischnochitons. It is not closely allied to any 

 other Australasian Chiton.
