M. Cossmann has recently renamed this group Strombocolumbus, 
under the impression that the name S¢trombina had been pre- 
occupied by Bronn; had he, however, consulted the original 
reference, he would have seen that Bronn used this name to denote 
the group of genera forming the family Strombide, and not in 
a generic sense at all. The name Sfrombina may therefore be 
retained with perfect propriety for the well-marked group of 
Columbellide which is typified by C. gibberula, Sby. This group 
will certainly prove worthy of generic rank.
