II. External maxillipeds sabpediforni, the antero-external angle of the 

 menis being: dilated. Dactylus of last pair of legs about half as 

 long as its propodite and opposed to a tubercle on the posterior 

 border or proximal end of the latter joint. Basal joint of eyestalk 

 not entirely hidden : — 



1. Carapace not depressed, its hepatic spine some distance 



behind the level of the supra-orbital spine ... ... HoMOLi. 



2. Carapace depressed, its hepatic spine almost on the same 



level as the supra-orbital spine ... ... ... Paromolopsis. 



None of the eiglit Indian species of Eomolidse are likely to fall in the way 

 of ordinary collectors, since five of them inhabit depths between 100 and 1000 

 fathoms, and of the other three only one has, so far, been taken in less than 50 

 fathoms of water.

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 eyestalks, and 

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

 carapace. The eyestalks are long and the slender basal joint is slightly longer 

 than the terminal joint. 



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

 expiratory canals are very well defined. The external maxilHpeds are subpedi- 

 form. 



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

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

 but have the propodite dilated near the basal end and never twice the length of 

 the dactylus. 



The abdomen of both sexes consists of seven separate segments and is rather 

 broad. 



Distribution : West Indies and Atlantic coasts of North America, Azores 

 and Atlantic coasts of Europe, Mediterranean, East Indian Seas from Cape 

 Comorin to the Philippines : commonly at considerable depths up to nearly 

 500 fathoms.
