This is the common soldier-crab of our seas. It inhabits almost all of the univalves that 
are found on our coasts. The right claw is generally but not always the largest, as I have 
seen a specimen in which the contrary was the case. 
It is generally placed in British collections as Cancer Bernhardus of Linné, but I cannot 
venture to affix any synonym to it, as the descriptions of authors are too general, and many 
species agreeing with their characters are found in the European Ocean. 
The twisted claws distinguish this from all the other species which I haye yet seen. 
PAGURUS PRIDEAUX. 
Fie. 5 et 6. 
P. manibus granulatis; carpis angulo interno spinosis; brachiis apice spinulosis; pedibus 
secundis et tertiis obscuré submuricatis ; unguibus tenuibus, supra subserratis. 
Fig. 5, Pagurus Prideaux. 6, in Scaphandre lignario. 
Pagurus Prideaux inhabits the sea on the southern coast of Devon, and is most common 
in the Sound of Plymouth. 
It is named after C. Prideaux, Esq. by whose friendly assistance in sending me a good 
series of specimens I am enabled to ascertain that itis distinct from the preceding species. 
Mr. Prideaux has observed it in a vast variety of habitations, even in the tubes of the 
Dentalia, and in the shell of Scaphander lignarius.
