No. 195, specimens sent by Dr. Gilchrist from East London 

 (shore) and from Three Anchor Bay. 

 1907. P. chabrus, Eathbun, Smithson. Misc. Coll., vol. xlix., p. 122, 

 correction in footnote of Stimpson's P. tomentosa. 



Stimpson says: " White refers this species, perhaps ustly, 

 to the Cancer chabrus of Linnaeus. But the identification does 

 not appear to rest upon comparison of the original specimens, 

 and until this is made we prefer to use a name to which we 

 can refer with certainty. It is rather common about the rocks 

 at half-tide in Simon's Bay, Cape of Good Hope." 



Though now accepting the name P. chabrus, in deference to 

 better authority than my own, I may refer to the arguments 

 I have previously used in favour of P. capensis, which is of 

 older date than P. tomentosa.
