species is excluded by the length of the last pair of 
walking legs, which in Cyllopus are rudimentary. 
This species was first taken by Kroyer, in Greenland, 
from whence it is also recorded by Milne Edwards. The 
specimen from which our description and figure are 
taken was sent to us from the Moray Frith by the Rev. 
Geo. Gordon, to whom we are indebted for the accom- 
panying sketch, taken by Miss Gordon from a scene on 
that Frith.
