A fresh look at figure 470E
in Bahamian Seashells

Figure 470E in Bahamian Seashells depicted a very beachworn sinistral shell that was identified as a species of Gibberula.

The figure is reproduced below (left) and reversed (right) to show what the shell would look like if dextral.

The shell is now considered to be a very poor example of an immature, sinistral  Prunum apicinum.
