690 DR RAMSAY H. TRAQUAIR ON THE DISTRIBUTION OF FOSSIL FISH-REMAINS 



the Edge Coal Series above. The specimen was found by the late Dr MacBain, and 

 by him presented to the Edinburgh Museum. 



Wardie Shales. — Here we are first introduced to the richness in fish-remains of the 

 Carboniferous rocks of the Edinburgh district. These shales directly overlie the 

 Granton and Craigleith Sandstones, and are estuarine in character, though containing 

 some marine bands with Myalina, Schizodus, Lingula, etc., but no hinged Brachiopods. 

 They are extensively exposed on the shore between Granton Quarry and Wardie, 

 the last-named locality being that from which Lord Greenock collected the fishes 

 described and figured by Agassiz, and which has since that time afforded to other 

 collectors, myself included, much fine additional material. 



Most of the fishes which have been collected at this locality (Wardie) are contained 

 in hard clay-ironstone nodules, of which a great quantity may be seen on the beach, 

 both in situ and detached from the shaly matrix. Coprolites form, however, the nuclei 

 of the immense majority of these nodules, so that the expenditure of much time and 

 patience is necessary towards obtaining specimens of fishes. 



The list from Wardie beach, brought up to date, is as follows : — 



Pleur acanthus, sp. Rhadinichthys omatissimus (Ag.). 

 Acanthodes sulcatus, Ag. „ carinatus (Ag.). 



Megalichthys, sp. „ brevis, Traq. 



Rhizodus Hibberti (Ag.). „ fcrox, Traq. 



Gonatodus punctatus (Ag.). Nematoptychius Greenocki (Ag.). 



Elonichthys Robisoni (Hibb.). Eurynotus crenatus, Ag. 



„ striatus (Ag.). Wardichthys cyclosoma, Traq. 



Notes on Agassiz's species. — Amblypterus nemopterus, Ag., is included in Elonichthys Robisoni 

 (Hibb.) ; Eurynotus fimbriatus, Ag., is a synonym of E. crenatus, Ag. 



In shales exposed in the banks of the Water of Leith at Woodhall, close above the 

 marine band (Schizodus -bed) belonging to the Wardie Shale horizon, Tristychius 

 arcuatns, Ag., Elonichthys Robisoni, and Eurynotus crenatus were collected by the late 

 Mr John Henderson. The last-named fish has also occurred in the shale immediately 

 overlying the sandstone at Craigleith Quarry. 



Hailes and Redhall Sandstones and Shales. — The Wardie beds are succeeded in 

 Midlothian by the Hailes and Eedhall Sandstones with associated shales. At Hailes 

 Quarry, shale overlying the sandstone contains clay-ironstone nodules which have 

 yielded Acanthodes sulcatus, Tristychius arcuatus, and Diplodus, sp. Shales seen in 

 the bed of the Water of Leith between Slateford and Colinton, and reckoned to this 

 group, have also yielded RhadinichtJiys carinatus, Rh. omatissimus, and Eurynotus 

 crenatus. 



Pumpherston Shales. — The next fish-bearing horizon in ascending order with which 

 I am acquainted in the Edinburgh district is that of the Oil Shales, which in Linlithgow-
