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, the terminal joint (with the eye) being nearly 
as long as the basal joint. 
The epistome is fairly or very distinctly marked off from the palate. 
The expiratory 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 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. 
The branchial formula is as follows :—

In my Account of the Investigator Deep Sea Brachyura, I have 
proposed the following subdivision of the genus Homola :— 
1. Homoa. Carapace square-cut, its broadest part being in front, 
across the middle of the gastric region: the linea anomurica rather
