The Eurypterid-bearing Deposits of the Pentland Hills. — Report of 

 the GoTtimittee, consisting of Dr. R. H. Traquair (Chairman),. 

 Professor T. Eupert Jones, and Mr. Malcolm Laurie {Secretary), 

 {Drawn up by Mr. M. Laurie.) 



In pursuance of the object for which the Committee were appointed Mr. 

 Laurie spent three weeks in the Pentland Hills superintending the ex- 

 cavations necessary to expose the fossiliferous beds. Three men were 

 employed on this work, and the grant was more than expended on wages 

 alone. Considerable difiBculty was experienced in clearing the beds 

 owing to the constant falling in of the superincumbent rocks, which are 

 much shattered. The fossiliferous beds were removed in as large masses 

 as their highly-jointed condition would allow ; and it seemed best to 

 convey the material to some place where it could be examined at leisure. 

 Part of the material (about one and a half ton) lies at present at Mr. 

 Laurie's home in Duddingston, and the rest is safely deposited at Carlops, 

 not far from the spot where it was procured. 



Owing to considerable delay and difiiculty in obtaining permission 

 from the proprietor to make the excavations in question, Mr. Laurie has 

 not had time to examine more than a very small quantity of the material 

 procured. 



The results, so far as they go, are promising, some half-dozen good 

 specimens — including a large Hurypterus ? sp., Stylonurus ornatus, Dre- 

 panoptems Pentlandius, &c. — having been found, together with a large 

 number of fragments of various forms. 



Tour Committee desire to be reappointed, and request that a further 

 sum of 101. be granted to provide assistance in developing the material 

 which has been procured from the excavations.
