I had this genus in some of my samples and they totally stumped me. After consulting a few refs and websites, including LTS, I found the specimens I had look exactly like this, but identified them as M. cuneiformis based on Abbott's (1974) description.

M. striata has a more elongate, pear-shaped shell and a rounded callum over the foot gape. Here are some other online refs that I use when identifying my molluscs in addition to LTS.

I have much more material now than I did in 2008, including specimens of both species. esalewsk is quite correct, the shell I illustrated as M. striata is M. cuneiformis. I have revised the presentation accordingly.

Sincerest appreciation to esalewsk, as we want LTS to be as accurate as possible.
