NEOCENE MOIvIvUSCA OF TEXAS, 

 Or, 



Fossils from the Deep Well at Galveston.* 



By 



Gilbert D, Harris. ' 



In a recent article by the present writer, published in the Phila- 

 delphia Acadeni3^'s Proceedings, reference is made to a monograph 

 on the Tertiary Mollusca of Texas, which, owing to the lack of 

 funds at the disposal of the State Geological Survey, had re- 

 mained for some time unpublished. 



That the reader maj^ have a clear idea as to what part of that 

 monograph the Academy published and what part we purpose to 

 bring out in this Bulletin, a summary of its contents is here given 

 just as it was when completed, December 23, 1893.
