The function of the flared lip remains enigmatic. In strombids it may help to support the relatively heavy shell on soft sediments. However, most eulimids are parasites on echinoderms. Whether

Habitat information was obtained from M. Severns (pers. comm. 12/2015): “The area the specimens came from is pretty much defined by its depth as far as the sediment and habitat is concerned. It is shallow by

standards, which made it very interesting right from the beginning. The bottom is a series of rounded hills that were surely islands just 10,000 years ago with several relatively flat “bays” between them as well as “channels”. Near the upper slopes we found fossil corals and avoided the summits of the hills due to rock so most collecting was done on the lower slopes, in the channels and on the flat sand and silt bottom pockets between the hills which had only occasional hard substrate. A couple deeper areas with large flat expanses must have been bays at one time. Three are very obvious on Google Earth. If I remember correctly the samples came from one of those flat areas which had numerous calcareous red algae “balls” which quickly filled the dredge.”

The justification for erecting the new taxa is borrowed from statistics: strong, highly consistent differences permit to show significance with few data points. The species is as distinct from any existing genus, as member of existing species are from each other. Accordingly, it is better to introduce a new genus rather than to force it into an existing genus where it does not fit.</paragraph>
