* /. rolmsta, Kr., is omitted, because I am not aware that this widely 

 diffused pelagic Crustacean really inhabits the shores of Greenland. Kjoyer's 

 ipecimens were captured between Iceland and Greenland, in 60*^ lat. N. 



t Considering the known relations between Anceus and Praniza, it might 

 be presumed that these (43a and b) are but the two sexes of one species.
