Geological axd Geographical Disteibutiox of Species. 



The geological and geographical distribution of the species obtained 

 from the Maryland Eocene has already been indicated in a general -way 

 in the discussion of the various stages, substages and zones. A much 

 more complete presentation of the distribution of all the forms is given 

 in the accompanying tables and in the chapter on systematic paleon- 

 tology with which the report closes. Any further attempt at a discus- 

 sion of the subject at this time would lead to much needless repetition.
