This is a common species in the harbor of New-York, but they do not appear to be as 
numerous now as they were twenty years ago, when they were caught from the wharves and 
sold for bait. They are known under the names of Anchovies and Sand Smelts. 'They are 
esteemed a savory food. ‘Their present ascertained geographical range extends from South- 
Carolina to Cape Cod in Massachusetts. We are at a loss to know why Cuvier and Valen- 
ciennes changed the prior and appropriate name given to this species by Dr. Mitchill.
