Front with a distinct rostral projection. Ocular peduncles scarcely so massive as 

 those of Pagurus, the basal scales of moderate size and separated by a wide interval. 

 Antennal acicle elongated and slender, the flagellum long and naked. Chelipedes rarely 

 subequal, the right usually larger ; the fingers moving in a horizontal plane, and 

 calcareous at the tips. Penultimate pair of legs subchelate.
