A Marginella of simple huild, allied to other Gibberuhe, e.g. maza- 

 gonica, Shoplandi, etc., from the same seas, but differing in several 

 points. Firstlj' in form, the present species being roundly oval 

 elliptic ; secomilj- in tlie strong plication, extended over the greater 

 portion of the frontal surface in an oblique direction ; thirdly in the 

 multideuticulate inner edge of the outer lip. M. replicata is, so far, 

 rare, but few examples having occurred, and these dead and pierced 

 by carnivorous molluscs in every instance. The figure is taken from 

 a combination of two or three examples, each perfect (or imperfect) 

 in some particular.
