Fig. 8 Eupagurus pollicaris 



Asymmetric forms with abdomen large but its integument not 

 calcified. Abdominal appendages much reduced. Inhabit empty 

 gasteropod shells. 



In order to protect their soft abdomen, these forms ensconce them- 

 selves in empty gasteropod shells, and from this circumstance are 

 known as hermit crabs, having a fancied resemblance to a hermit 

 in his cell.
