This species was procured from trawl refuse which had been 
taken near the Eddystone Lighthouse. 
These two species may be only male and female. In general 
form they are not very dissimilar, but there is a considerable 
variation in the microscopical structure of the dermal tissues. 
The former species W. cwcula is undoubtedly a female, having 
been taken with ova. The latter we have not determined. 
Genus, Acanthonotus. — Owen.

equal. Hands feeble, subchelate. Telson single, cleft to the 
apex.

This species is pretty generally distributed from the Shetland 
to the coast of Oornwafl, it has been dredged at Falmouth, and 
found in trawl refuse brought in from the Channel off the Cornish 
coast. But all the specimens were taken from the back and gill 
chamfers of the Corwich crab [Maia squinado). They appear to 
live among the thick fur on the back of this spider crab, as if it 
was their natural habitat, their prehensile legs being pecu- 
liarly adapted for lioldiug tliemselves on that animal.
