1911] Teller, Fossils from the Palceozoic Formations. 181 



Volume after volume has been gone through without any results 

 whatever especially where we might look for good results ; and 

 then good results were obtained where little or nothing was ex- 

 pected until at the present time we have about completed our task 

 and while we do not claim absolute accuracy as to all of the species 

 being enumerated we have reasons to believe that it is practically 

 complete. In almost every case the types with few exceptions 

 have been located, thus covering the ground up to the present time. 

 As previously stated, in the near future there are to be a number 

 of new species added to the list by the publication of a report which 

 is now ready to go to press. These we do not feel that we can 

 properly include in our list at this time as it would be to trespass 

 upon the rights of priority of the author. 



It is rather amazing the number of synonyms that have been 

 introduced into the description of the fossil remains that have been 

 collected in the state, made in many instances by the most able 

 describers of such objects; and the elimination of such species 

 should take place as soon as fully determined so that the 

 science may not be burdened with a long list of useless terms. In 

 many cases we find from two to three or more such instances 

 where a single genus has been given different generic names ; the 

 same applies to many of the species. 



In making up our list of types described from the state all 

 synonyms have been worked out and while retained as a matter of 

 reference they have been referred to their proper equivalent ; they 

 have made the work more laborious than expected and have been 

 the one chief stimulus to urge on the completion of our task and 

 to make every effort to have the list of types as complete as pos- 

 sible. As now worked out the list contains of the known valid 

 species.
