THE CRUSTACEA OF NEW JERSEY. 179 



lobes small. Eyes either distinct or imperfectly developed. 

 Superior antennas provided with an accessoiy appendage, longer 

 than inferior. Latter more strongly built in male than in female, 

 in former with very movable articulation between penultimate 

 and antepenultimate joint of peduncle, flagellum multiarticulate. 

 Mandibular palps, well developed, triarticulate. Maxillipeds 

 with masticatory lobes short and broad, armed inside with strong 

 flattened spines. Gnathopoda rather unequal, anterior ones much 

 stronger than posterior, and somewhat differing in male, pro- 

 podus long and broad, subcheliform. Peraeopoda comparatively 

 slender, three posterior pairs successively increasing in length, 

 and with basal joint more or less expanded. Pleopoda normally 

 developed. Last pair of uropoda very small, with basal joint 

 expanded inside. Telson comparatively large, lamellar, rounded. 

 Differs from CoropJiuim in the presence of a distinct acces- 

 sory appendage to superior antennas and in structure of gnatho- 

 poda. Species few.
