Supposed formerly to have been the young of the Shad ‡, but clearly proved by Mr. Yarrell to be a distinct species. Found only in the Thames, which river it ascends in April, sometimes as early as the end of March. Abundant throughout the Summer about Greenwich and Blackwall, but never found higher up the river than the locality last mentioned. Supposed to deposit its spawn during Winter. Swims near the surface. Food minute shrimps.
