100 RECORDS OF THE AUSTRALIAN MUSEUM. 



When alive the shell is entirely covered by a dense buff epi- 

 dermis, which peels off dry specimens. An example of the 

 animal which I purchased at Mapoon, from an aboriginal who 

 proposed to eat it, served my friend Mr. H. L. Kesteven as a 

 subject for anatomical study. ^* 



In previous articles I have discussed the synonomy and egg 

 capsules of the species.'* 



Add. — Since the above has been in print the South-western 

 range has been extended by the receipt from Mr. J. M. Sheridan 

 of an egg-case of M. aruamis, collected on Carnac Island, seven 

 miles South-west of Fremantle, W.A. The eastern-most record 

 is a dead shell I observed on the beach at Masthead Island, 

 Capricorn Group, Queensland.
