space. Very large eyes are also found in M. patagonica and M. anomala, but in these species the 

 armature of the telson is too distinctive for them to be confused with M. macrops. 



Distribution. This species has been taken at thirteen stations around the Falkland Islands and at 

 two in Cumberland Bay, South Georgia. It would appear to be quite abundant in suitable localities.
