JDefrancia and Mangelia. Jeffreys introduces the form of the apex as a 
new systematic character for the small Pleurotoma-WkQ European shells. He 
unites those in which it is somewhat stiliform, as in Ceritliiopsis, finely 
pointed, and minutely reticulated, into a genus, Defrancia, whilst those in 
which the apex is regular and blunt are reunited by him into the old genus 
Pleurotoma, the notch in the outer lip being in some of them, as P. nivalis 
(Lov^n), as deep as in the typical exotic species. All the species of Defrancia 
in this sense are without operculum ; among the Pleurotomce there are some 
with and others without operculum. The British species are arranged by the 
author in the following manner (Brit. Conch, iv. pp. 360-399)
