The Uurypterid-bearing BeposiU of the Pentland Hills. — Second Report 

 of the Committee, consisting of Dr. E. H. Traquair (Chairman), 

 Professor T. Rupert Jones, and Mr. Malcolm Laurie (Secretary). 

 (Drawn up by the Secretary.) 



During the past year a considerable amount of time has been spent in 

 developing the material already acquired. The grant of money was chiefly 

 expended in securing the assistance of Mr. Henderson, the original dis- 

 coverer of these fossil beds. Thanks to his able assistance a considerable 

 part of the material has been worked over with very satisfactory results, 

 thougli much yet remains to be examined. 



The specimens already obtained include five species of Eurypteric'oe
