ANNUAL REPORT OF THE 



killen, of Florence Court, Ireland, to Professor A. H. Worthen in 

 1865; it is accompanied by a complete list of specimens. The

 States. Lastly, some important material was acquired by the

 opportunities were enjoyed on this trip for the study of the 

 principal fossiliferous horizons, as well as public and private 

 collections.
