Generic character. Superior antennas short, having a multi- 

 articulate flagellum and a secondary appendage. Inferior 

 antenna longer than the superior; very robust; flagellum 

 uniarticulate. Mandibles having an appendage. Third sia- 

 gonopodos unguiculate. Gnathopoda chelate, subequal. Perei- 

 opoda short, subequal. Ante- and penultimate pairs of 

 pleopoda biramous, and closely associated ; ultimate pair 

 unibranched. Telson single. 



IN this genus the eyes are round. The superior 

 antennae are shorter than the inferior; they terminate 

 in a multi-articulate flagellum, and bear a secondary 

 appendage. The inferior antennae are strong and have 

 a uni-articulate flagellum of great size and strength. 

 The mandibles are furnished with a three-jointed ap- 

 pendage. The maxillipedes terminate in a sharp finger. 

 The first two pairs of legs have chelate hands. The 

 coxae are short ; the legs are also short and strong. The 

 ante- and penultimate pairs of caudal appendages are 

 biramous, and closely associated in their position ; the 

 ultimate pair are single-branched, and the telson is single 

 and squamiform. 



This genus was first described by Philippi from speci- 

 mens which he procured from the dockyards of Trieste.
