are alike in having a pair of snow-flake rings, but eximia has flat 

 whorls and a straight or concave spire, whereas peroniana has a 

 convex profile and rounded whorls. P. peroniana has a peculiar 

 epidermis frilled in thin radial lamella?, at the rate of about forty 

 to a whorl. Columbella nycteis Chenu,* a smaller form, rather dif- 

 ferently coloured, from an unknown locality, makes a near ap- 

 proach to the Sydney shell. P. peroniana extends to Lord Howe 

 Island. As the species proves to be distinct, and the name to have 

 been pre-occupied by Gould, the choice of a new name becomes a 

 necessity.

Reeve replaced Menke's name by another, on the ground that it 

 was preoccupied. But this was not the case, and Menke's prior 

 name should be restored.
