COi\CLUDIXG REMARKS. 



22; 



I cannot close this Monograph without expressing my sincere thanks to the 

 authorities of the Geological Survey, the j\Iuseum of Science and Art, and the 

 Royal College of Science for Ireland, for the loan of the fossils under their charge. 

 Their kindness and liberality in placing the necessarj' material freely at my 

 disposal, and also their indulgence to me in the matter of time, have greatly 

 facilitated the completion of my task. 



To the authorities of the British Museum (Natural History) I am equally 

 indebted for their courtesy in according me all possible facilities for the study and 

 illustration of the fossils contained in the Geological Department applicable to this 

 Monograph.
