Dear Conch-L'ers,
A problem I have had in my studies of some North American polygyrid land
snails, for example, Neohelix, Triodopsis or Mesodon, is the accurate
measurement of the height. The shape of a poygyrid shell makes it difficult
to reproducibly position the shell between the jaws of calipers to measure
its height. I will appreciate your suggestions, comments, ideas to make such
measurements easier, while maintaining accuracy & reproducibility. Thanks.
