226 ANNALS OF SCOTTISH NATURAL HISTORY 



ever brought together of the fossils from the " Eurypterid- 

 bearing " beds of Gutterford Burn, near Carlops, whose re- 

 markably fossiliferous character was first discovered by Mr. 

 John Henderson, a well-known Edinburgh geologist. And 

 it was from specimens obtained by the Museum from Mr. 

 Henderson that Professor Malcolm Laurie, a few years ago, 

 described five new species and one new genus of the 

 interesting extinct group of Eurypterida. 



Mr. Hardie was an enthusiastic collector, and devoted 

 much patient work to bringing together this important 

 collection, which is now the property of the nation. It 

 consists of 866 specimens in all, mostly from Gutterford 

 Burn, though a certain number are from the North Esk. 



Naturally the most interesting of the Gutterford fossils 

 are the Eurypterida, represented by 237 specimens, both 

 entire and fragmentary, of species of Eurypterus, Stylonunis, 

 and Drepanopterus. Here there is material for a considerable 

 extension of our knowledge of the details of the species 

 concerned. Of the remaining fossils from this locality, the 

 most numerous are Echinoderms, though Trilobites, Mollusca, 

 Brachiopoda, and Graptolites are also represented. 



Only 132 specimens are from the North Esk beds, and 

 these are chiefly remarkable for the fine series of the sponges 

 Plectoderma scitnlwn and AmpJiispongia oblonga which they 

 contain. An interesting series of sections of the limestone 

 pebbles of Silurian age, and containing corals, which occur in 

 the Lower Devonian Conglomerate of the Pentland Hills also 

 forms part of the collection.
