The differences between Lucas’ and Walker’s species appear to be 
so slight that there seems to be no necessity for keeping them separate. 
Much importance cannot be attached to the absence in Walker’s 
description and figures (except 2nd enathopod of ?) of the distal 
lobe on the 2nd joint of the 1st and 2nd gnathopods; it is easily 
overlooked unless the limb be examined exactly in profile. Chevreux 
figures it in both gnathopods of both sexes of his specimens, which he 
assigns to intermedia, from the Gambier Archipelago. Nor can the 
length of the flagellum of the 2nd antenna of ¢ be counted as a
