other section of the marine fauna. Among the Amphipoda the 



genera Cijiiroidia and leilius, are perhaps the most remarkable, 



and both must be regarded as occupying positions separated by 



considerable intervals from all other described forms ; but almost 



equally characteristic are such as Amaryllis, Glycera, XenocJieira, 



Polyclieria, and W^yvillea ; though these find near allies among 



genera from other regions. Among the Isopoda of Australia, 



there are probably, almost as many peculiar and aberrant forms 



as among the Amphipoda, though the variety of species and the
