clerably increased. In the fossil state many Eulimai are 

 met with, even in the older formations. 



The animal of Eidhna was first made known by 

 Philippi. It has since been examined and described by 

 several malacologists. Yet, strange to say, by more than 

 one recent writer it has been treated as amongst those im- 

 perfectly understood groups of which only the shell has as 

 yet been made known.

The chief character by which the shells of this genus 

 are distinguishable from each other is the proportion of 

 their parts. For all the species are alike lustrous, smooth, 

 and flat-surfaced, and very few of the known species 

 arc otherwise than snowy white. Hence considerable
