I have seen but one of this characteristic species : the aperture is 

 allied in form to that of Colvmhella PueUa, Sowerby, It may be 

 convenient to readers to state, that the species Col. Puella is by acci- 

 dent, in the index of the 'Thesaurus Conchyl.' of Sowerby, jun., 

 entered as Col. Nymphu.
