Munida subrugosa is abundant in the Patagonian region ; it occurs also at the 

 Auckland Islands (White), in the New Zealand seas (Miers), and I am enabled to record 

 the species from the South Atlantic and a variety from South Australia. It may be said, 

 indeed, to represent Munida rugosa in the southern hemisphere. In the Catalogue of 

 New Zealand Crustacea, and subsequently in a more I'ecent work, Mr. E. J. Miers states 

 his conviction that the so-called Grimothea gregaria is merely an immature stage of 

 this species, a belief based on the facts that the two exhibit many points of similarity and 

 occur in the same localities. The Grimothea is moreover apparently pelagic in habit, and 

 it may be added that its general appearance favours the theory of immaturity. In spite 



1 Milne-EJwards regarded Guerin's figure as that of a distinct species, and applied tlie name Grimothea " Duperreii " 

 to it
