■ My examination of these well-authenticated examples 

 leaves no room for doubt that they belong to one species; 

 indeed, there is little individual variation among them. 

 "E. callista'^ must, therefore, become a synonym of E. 

 marife. I am indebted to Major M. Connolly, who has 

 kindly examined the types in the British Museum for me, 

 for the following confirmation of my views: "In E. mar if© 

 the trace of a cusp on the upper part of the labral tooth is 

 slightly more prominent than in E. callista. The rest of 

 the dentition, together with the form and sculpture, is similar 

 in both types, and the shells are undoubtedly conspecific." 



He also furnishes me with the following revised dimensions 

 of the types as taken by him : 



"Type of E. marine, height 3*00, width 1*35 mm. 

 „ „ E. callista, height 2-80, width 1-30 mm."
