The marine fish fauna of New York represents a highly diverse species assemblage, compose of both migratory and resident taxa that utilize a wide variety of habitats. Recently the New York State Museum took position of Dr. Howard Riesman’s personal ichthyology collection, which included many specimens from Shinnecock Bay, Long Island. Examinations of these specimens has provided evidence to suggest that an additional 4 species should be added to previously compiled lists of marine species known to occur in the vicinity of New York. The prior lack of recognition of the presence of these species in Shinnecock Bay is apparently attributable to a number of factors, including historical taxonomic confusion, actual range expansion, aquarium releases, and simple lack of historical documentation of rare or transient species.
