The following is a full list of the Ostracod 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.
