A REEXAMINATION OF SOME SPECIES OF AMPELISCA (CRUSTACEA: AMPHIPODA) FROM THE EAST COAST OF NORTH AMERICA
Ampelisca verrilli n. sp. occurs from the intertidal to 50 m from southern Cape Cod to at least North Carolina. Individuals from North Carolina are small and slightly divergent in morphology from those from Massachusetts. A. macrocephala Liljeborg, with which A. verrilli has been confused for many y...
