4 8 DISCOVERY REPORTS 



a careful analysis of the horizontal and vertical distribution of all the species of Eucopia and the present 

 collections do not add materially to his findings. 



I have added a fifth species, E. linguicaudata, to the genus. Unfortunately there is only one specimen 

 of this interesting form, but the shape and armature of the telson are so distinctive, that it cannot be 

 referred to any of the known species.
