The first antennae are made up of a peduncle of three segments, followed by a flagellum usually multiarticulate, and sometimes also by a secondary or accessory flagellum. The first joint of the peduncle is characteristically very stout in the Lysianassidce. The flagellum may be very short as in Orchestia. The accessory flagellum is lacking in the Ampeliscidae, Orchestiidse, Stenothoe, Sympleustes, Calliopius, Pontogeneia, Dexamine, Batea, Amphi- thoe, Ericthonius, Corophium, Siphonoscetes, and iPodoceropsis.
