Note
Heterosquilla armata (Smith) is an uncommon species of mantis shrimp in the family Lysiosquillidae which was originally described in 1881 from material obtained primarily by the U.S. Fish Commission Steamer "FISH HAWK" off the coast of New England (see Manning, 1969: 52 ). In spite of numerous collections by many agencies in the waters off the northeastern United States and elsewhere along the eastern seaboard, apparently only one additional specimen has been taken.
