The distinguishing character of the larvae of the two genera is the palp of the first maxilla—not the second as given by Lebour (1930)— which is composed of one segment in Mnnida and of two in Galathea. The aciculate form of the antennal scale, as figured by Gurney and Lebour, cannot, therefore, be looked upon as a generic feature, and it would seem probable that the two genera merge one into the other in this respect. The rostrum and the postero-lateral spines of the carapace are not as long in the Falkland larvae as in M. banffica larvae, characters showing an approach to the larvae of Galathea. The telson remains the same as in the northern species, having seven spines.
