1. biologyThe segment next to the flagellum of the antennae of crustaceans.

   Merocerite or second joint also furnished with a few yellow hairs, like the carpocerite; terminal filament or procerite a little shorter than the carapace, multiarticulate and provided with long yellow verticilated hairs.

   1881, Hermann Schlegel, Notes from the Leyden Museum - Volumes 3-4, page 133

   In this genus, the basicerite, ischiocerite, and merocerite are much thicker and stronger than the corresponding joints of any of the other appendages; and in the closely allied Scyllarus, the facial region of which is, on the whole, similarly constructed, these joints become extremely expanded and flattened, and are succeeded by no procerite.

   1888, Thomas Henry Huxley, A Manual of the Anatomy of Invertebrated Animals

   There is a large tuft of tactile setæ at the base of the procerite, and a few are continued from that point down the outer margin of the carpocerite; but all the setæ below that point on the upper surface are fringing setæ, as that part is covered by the antennules and the squame.
