ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 665 



Bceckellopsis Mraz. possesses only the species B. bergi (Rich.) from 

 Buenos Aires and S. Patagonia. 



Parabceckella Mraz. is made up of P. brevicaudata (Brad.) from Kergue- 

 len and Punta Arenas. 



This distribution is so remarkable, including only S. America, S. Georgia, 

 Kerguelen, Australia and New Zealand, that this group of genera, which 

 are no doubt closely related to one another, clearly is to be classed with 

 those freshwater and land animals that point to a former connection of 

 these regions. 1 Under the same head comes also Lepidurus hatcheri Ortm., 

 of which we have demonstrated above, that it is most closely allied to 

 L. angasi Baird of South Australia.
