Carapace deep, longer than broad, quadrilateral or urn-shaped, with deep 

 vertical sides, the gastric region well demarcated and occupying the anterior half 

 of the carapace, the linea anomurica distinct and dorsal. 



Front narrow, forming a rostrum, which is either entire or bifid at tip and 

 has a spine, often of large size, on either side of its base. 



The orbits are quite incomplete and do not even conceal the eye-stalks, and 

 the eyes, which project far outside them, are retractile against the sides of the 

 carapace. The eye-stalks are long and are composed of two joints, a slender 

 basal joint, and a swollen terminal joint that carries the eye. 



There are no antennulary fossas : the antennules are large and their basal 

 joint is subglobular. 



The antenna-peduncle is long slender and freely movable from its base, and 

 is inserted in almost the same plane as the antennules : it is composed of 4 

 joints, the basal one of which has a strong " auditory tubercle." The flagellum 

 is extremely long. 



The epistome is fairly or very distinctly marked off from the palate. The 

 buccal cavern is subquadrilateral, but broader in front than behind ; the expira- 

 tory canals are very well defined. The external maxillipeds are subpediform. 



The chelipeds are rather slender and generally somewhat spiny. The legs 

 are long and more or less compressed and spiny, the last pair are dorsal in 

 position, and are subcheliform, but have the propodite dilated near the basal 

 end and never twice the length of the dactylus. 



The abdomen of the male consists of seven separate segments and is rather 

 broad.
