Philippi's figure is unmistakeable, whereas Reeve's, fig. 93, is 

 very indifferent. The sculpture is very variable, occasionally 

 unusually developed. Mr. Smith, P. Zool., S. 1878, appears 

 to consider this Andaman form as L. ventricosa and compares 

 it with his L. melanacrne and L. novae-zelandice.

Long. 9, diam. [vix] 8 mil. This form, exactly represented 

 by Frauenfeld' s fig. c., of coarser sculpture than the type, is un- 

 doubtedly only a var. of L. ventricosa; if it prove to be Gray's 

 species, as I expect it will, this latter name will have priority. 

 The specimen, from the same province of Ceylon as the next 

 form, L. nova-zelandice, has induced me to believe the latter 

 a distinct species ? I can perceive, however, no difference 

 except that of sculpture, and the shorter, more ventricose form 

 of L. ventricosa and its var. subgranularis, both characters very 

 variable in this species.

I am convinced this species was never found in New Zealand. 

 Prof. F. W. Button in 1878 records that he had never seen 

 specimens. As to the localities of Reeve and von Frauenfeld
