THE VOYAGE OF H.M.S. CHALLENGER. 
species procured at each Station a reference is added, by corresponding letters, to the 
other regions in which the same species occurred, so that its geographical distribution 
might be seen at a glance, and at the same time it will be observed that the extent of geo- 
graphical distribution is to a considerable degree correlative with the bathymetrical, 
the wider distribution being in most instances coincident with the shallower depths ; though 
to this there are some striking exceptions.
