280 REV. T. R. R. STEBBING ON STALK-EYED CRUSTACEA MALACOSTRACA 



shape of the carapace and on its rostral and antero-lateral spines, which in the 

 subrugosus form are more elongate than in gregarius. Dr Chilton, however, in 1909, 

 is still unconvinced, and propounds the theory that " the foliaceous maxillipeds of 

 Grimothea gregaria are associated with its pelagic habit," and that when it finds a 

 deeper dwelling-place successive moults enable it to assume shorter, less foliaceous, and 

 more infolded terminal joints to its external maxillipeds. He considers Grimothea 

 novsezelandise, Filhol, also a synonym of M. subrugosus. Making up for this loss to 

 the genus, Miss Rathbun in 1910 determines that Grimotea gregaria, Guerin, 

 1830-1831, is not the G. gregaria (Fabricius), but a distinct species, Munida coheri, 

 noticed by Doflein and Balss as M. cocheri. 



The Scotia obtained the cast skin of a large specimen, with well-pronounced 

 rostral and antero-lateral spines, which I am satisfied to call M. subrugosus.

Without venturing a decisive opinion on the controversy above considered, I can 

 affirm that several little specimens obtained by the Scotia belong to the juvenile 

 form described and figured by Mocquard as Munida gregaria (Fabricius). The 

 fourth joint of the third maxillipeds is not apically produced, and the two following 

 joints are distally dilated.
