The following is a full list of the Osrracop remains 
observed in the various lacustrine deposits referred to in 
the preceding notes. As considerable changes have quite 
recently been made in the nomenclature of the Ostracoda, 
and especially of the fresh and brackish water species, we 
have considered it advisable to add a synonomy sufficiently 
full to enable those not conversant with this group to more 
easily recognise the various forms referred to.
