Specimens of various sizes which I refer to this species were 
taken by Mr. Vallentin Jan. 28, 1899 (at the surface), Dec. 4, 
1901, in Roy Cove, Feb. 1, 1910, and in Whales Bay, March 11

Dr. Chilton discusses the question of the specific identity of 
M. subrugosus and M. gregarius, 11 which he definitely inclines to 
believe, though still adopting the later name for the species. As 
to the generic name, Grimothea Leach, 1820, seems to have page 
precedence over J/unida, but I forbear the dangerous task of 
arbitrating between the rival nymphs. 
Mr. Vallentin took MW. subrugosus at a depth of 4 fathoms in 
Whales Bay, 6 fathoms in Roy Cove, and Dec. 12, 1909, in 
““8 fathoms creek.” All these specimens were adult, and all but 
one of rather large size.
