Carapace seldom broader than long, subquadrilateral or subovoid 

 (sometimes snb-circular, or urn-sliaped, or sub-pentagonal), often (as 

 also the appendages) pilose. Front narrow. 



Orbits and antennulary fossae may either be altogether wanting, or 

 there may be common orbito-antennulary fossae into which the eyes and 

 antennules are both retractile. 



The antennal peduncle consists of four separate joints, and the 

 antennal flagellum is long. 



The epistorae is triangular or truncate-triangular, and is well 

 delimited from the palate. 



Tlie buccal cavern is quadiilateral, but is usually broader in front 

 than behind. The external maxillipeds may be pediform, or sub-pedi- 

 form, or completely opercular. 



The last pair of legs are dorsal in position, and, with few exceptions, 

 are prehensile slender and reduced in size, or even sometimes rudiment- 

 ary. The penultimate pair sometimes resemble the last pair. 



The abdomen in both sexes is large, and usually consists of seven 

 separate segments: in the male it has the usual anterior two pairs of 

 modified copulatory appendages : in the female it has the usual four 

 pairs of ovigerous appendages and, in addition, a pair of smaller 

 uniramous appendages situated on the first segment. 



The genital ducts of the female open upon the bases of the 2nd pair 

 of legs (third pereiopods) : those of the male open on the bases of the 

 fourth pair of legs (5th pereiopods). 



The gills are usually phyllobranchia), but may be trichobranchia^,
