This species should stand undei' the name variegata 

 Anton, if both forms really belong to one and the same 

 species. Anton's species was described in 1839 and ^lenke's 

 about four years later. Krauss and ^Martens have united 

 them, but^ on the other hand^ Philippi decided to keep them 

 separate.

A beautifullittle species allied to E. foveolatus A Adams, 

 from Lord Hood Island. It is, however, much smaller than 

 that species, is more delicately sculptured, the spiral keels 

 being regular and simple, whereas in foveolatus they are 

 subspinose where the oblique lamellas join them. Besides the 

 six carinas mentioned above, a seventh is noticeable upon the 

 body-whorl close to the suture, and this may be traced upon 

 the penultimate volution also.
