(which, it may be noted, is the locality from which Busk's Hippuraria egertoni was obtained), 

 on Portunus depmrator\ and Sars' record from Christiania, on Geryon tridens. In 1895 Duerden 

 mentions the occurrence of the same species, from another Irish locality, on Gonoplax angulata, 

 in special abundance on the anten na e. The list which I have given above shows 

 that it is of common occurrence in more southern localities; and in particular on Gonoplax 

 from Portugal, Spain and Algoa Bay. The last locality suggests that an examination of the 

 Crabs and other Crustacea from the Malay region might be expected to result in the discovery 

 of specimens of Triticella. It may be noted that Annandale x ) has recorded T. korenii from 

 Squilla fasciata obtained off Japan. 



If Hippuraria is a synonym of Triticella, it follows that the species placed in the former 

 genus by previous authors must find a place elsewhere. I have cited H. verticillata Hincks, and 

 II. armata Osburn under Mimosella verticillata and Buskia setigera respectively. H. elotigata 

 Osburn (t. cit., p. 256) appears to be a Triticella.
