" distinguisbed by the upper three or four whorls being 



invariably longitudinally ribbed, the ribs being not at all pro- 

 minent and slightly but distinctly arcuate ; quite young specimens 

 show the ribbing throughout, the ribs only becoming obsolete on 

 the lower portion of the last whorl. Generally but slightly 

 decollate, eight whorls remaining ; covered with a rust-brown 

 coating, beneath whicli the shell is light green, irregularly and 

 very slightly spotted with brown below the suture ; throughout 

 spirally striated ; a single specimen only has this spiral sculpture 

 obsolete on the central portion of the last two to three -whorls. 

 The majority ef specimens are smaller than type-figure of 

 M. nevilli, and have the last two whorls increasing much more 

 rapidly in breadth "
