 1909. Epicarides, Gilson, Bull. Sci. France-Belgique, vol. xliii., p. 78. 



The bibliography of this tribe given by Dr Gilson extends from 1722 to 1909 and 

 contains 279 references. 



Miss Eichardson gives Bopyroidea as an alternative name for the tribe, less significant 

 than that proposed by Latreille, which alludes to the circumstance that the members of 

 it are parasitic on other crustaceans, though with the disadvantage that eventually fresh 

 members may be found on non-crustacean hosts, and that actually many crustaceans 

 parasitic on other crustaceans do not belong to the Epicaridea.

To this family, in which the genera are already rather perplexingly numerous, I have 

 felt it necessary to add a new one, containing two new species. Three species are added 

 to older genera. Some notes are offered on Trapezicepon amicorum (Giard and Bonnier), 

 the specimen being derived from a different host from that on which the typical example 

 occurred. The new specimen is further worthy of note for containing, in place of eggs, 

 an obscure but remarkable parasite apparently of the same tribe. A very small species of 

 the genus Cancricepon is left unnamed for reasons assigned further on. 



In 1906 the late Professor Giard was able to announce that after prolonged efforts 

 M. Edm. Bordage at Beunion had discovered the host of Kepon typus, Duvernoy, in the 

 agile crab Ghrapsua striyosus (Herbst). For some reason unexplained in place of 

 Duvernoy's generic name Kepon Giard adopts the name Gmpsicepon, previously regarded 

 as distinct. He promises a much needed revision of Duvernoy's statements, but this 

 promise his lamented death has prevented him from keeping, thus leaving this particular 

 branch of the subject for the moment in some confusion.
