The telson bears a few setae in groups, and is divided 
dorsally into four lobes, with a small lozenge-shaped area m 
the middle ; the two terminal lobes are unequal, with a median 
cleft between them. The two anterior lobes have each an 
ear-shaped pit. 
The female has a large brood pouch. 
This littoral species is one of the largest and commonest 
hermit crabs of our coast, and varies much in size.

The animal is somewhat hairy, especially on the cheli- 
peds, the hairs there, however, not thick enough to hide the 
armature. 
The anterior portion of the carapace is rather flat above, 
sparingly pitted, rough or rugose towards the front and sides, 
with a depression behind the front, marked on eacn side by a 
short, slightly oblique ruga, then another small, depressed 
area lies beween this and the Hepatic region. The rostral 
tooth is very short, obtuse, and scarcely projecting farther 
than the prominences external to it ; these are rounded, and 
each is tipped with a very small denticle. The hepatic re- 
gions are rounded and slightly tuberculate ; they are sepa- 
rated from the other regions by a faintly marked, very ir- 
regular, longitudinal groove, which joins the cervical groove 
behind. The frontal margin is thickened. The portion of 
the carapace behind the cervical groove is thin, and shows 
some small disconnected areas of calcification. The branchial 
regions are moderately tumid and sparingly setose ; there is ^ 
tuft of setae on each side of the cardiac region. 
The ocular peduncles are moderately robust, not as long 
as the breadth of the anterior portion of the carapace, and 
somewhat constricted towards the middle. The basal scales 
are rather small, and bear five or six small red denticles on 
each. They are well separated from each other. 
The antennular peduncles reach nearly to the level of the 
eyes. 
The outer side of the first peduncular joint of the an- 
tennae bears one or two denticles. The second joint is hol- 
lowed above, its outer distal angle is produced, bearing four 
or five spinules, and there are one or two denticles at the 
inner angle. The acicle is moderately robust, quickly tapering
