While engaged in the revision of the nomenclature of the 

 species of these genera for the Report on the Brachyura of the 

 1 Challenger ' collection, now in course of preparation, I have 

 recognized some errors of determination into which I have 

 been led, in common with other students of the group ; and 

 having now subjected the whole of the material in the British 

 Museum and ' Challenger ' collections to a careful reexami- 

 nation, I think it useful to publish the results of my study of 

 the group, to redescribe the species, and present a synopsis of 

 their arrangement, which will be found to differ in some 

 important particulars from that given by Dr. R. Kossmann in 

 his work on the Malacostraea of the Red Sea*, and to include 

 references to some species and varieties described since it 

 appeared.
