Carapace longer than broad, linese anomuricx usually present. The eyes 

 are not retractile into orbits nor the antennules into pits. Basal antennular joint 

 subglobular. 



The slender basal joint of the eyestalk is almost always plainly visible, and 

 is sometimes of great length. 



The antennal flagella are, except in the Latreillidae, much longer than the 

 carapace. 



The interantennulary septum is a distinct vertical process, and is not formed 

 merely by the close apposition of the apex of the epistome to the front. 



The front forms a slender triangular prominent rostrum, which may be bifid 

 at tip and often has a spine on either side of its base. 



The division between the epistome and palate is distinct, but the vault of 

 the palate is shallow. 



External maxillipeds pediform or sub-operculiform. 



The chelipeds and legs are long and slender : the fingers are not channelled 

 en cuillere. Only the last pair of legs is dorsal and reduced in size. 



Sternum of the female broad, without any special longitudinal grooves. 



The abdomen of the male, and usually but not always of the female also, 

 consists of seven separate segments. There are no lateral platelets intercalated 

 between the 6th and 7th segments. 



The gills are phyllobranchijB, and the gill-plurpes vary in number from 

 14 to 8 on either side. 



The species are, for the most part, confined to deep water. 

 The Homolidea are divided into two families as follows : —
