PAGURUS FORBESII. 187 



compressed, the fourth joint spinous on the upper edge ; 

 the terminal joint hairy, spinous beneath. 



The whole of the legs with numerous small reddish 

 brown spots. 



This curious species differs obviously from every other 

 inhabiting our coasts. I discovered it amongst some 

 small Paguri, which I received through the kindness of 

 Mr. Corks, of Falmouth, and which consisted of no less 

 than four species, all obtained by him on that coast. The 

 other species with which it was associated, were P. Bern- 

 hardus, Prideauxii, and lavis. Of the present new one 

 there was but a single specimen. 



I have named this species after my distinguished friend 

 and colleague, Professor Edward Forbes, to whom I am 

 indebted for several interesting additions to the objects of 

 this work.
