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

 alHed in form to that of Columbella Puella, 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. Nijmpka.
