Geoffrey Smith (135, p. 108) recognizes, among the various names 

 given to the genus, only two certain species, P. yaguri and P. sulcahis. 

 Under the synonyms of the latter he records, as the hosts and dis- 

 tribution of the species : Pagurus cuanensis, chiracanthus and laevis, 

 from Danish and Norwegian Seas ; P. p)rideauxi and meticnlosus, from 

 Naples ; an unnamed host from French coasts ; Pagurus sp. ? from 

 Brazil ; and Ligella gracilis and affinis from Valparaiso. 



The species is recorded by Norman (130, p. 226) " on examples of 

 Pagurus cuanensis dredged in Teignmouth Bay." It was earlier re- 

 corded by him (127, p. 185), as "gregariously parasitic on Pagurus 

 laevis, off Sunderland. New to Britain."
