at all, it should in our opinion be in the sense in which it has 

 been employed by carcinologists up to the present time. To 

 use it instead of Platophium would be unjust towards the 

 author of that genus, and its altered use would lead to endless 

 confusion. The right course appears to be to let the name of 

 the insufficiently described Podocerus variegatus henceforth 

 sink into oblivion. Moreover, it seems very desirable 

 that a law of nomenclature should be enacted whereby a 

 generic name which has been employed in one sense for, say, 

 fifty years, should not be transferred to an entirely different 

 genus. In this particular case no delicacy need be felt 

 towards Leach, for perhaps no other author so wilfully 

 renamed species which were already described, and with 

 brazen face quietly placed below his own name the rejected 

 earlier name as a synonym.
