DR RAMSAY H. TRAQUAIR ON FOSSIL FISHES COLLECTED BY 



result of a comparison of this fish-fauna with that of other localities in Scotland in 

 which estuarine fishes of Lower Carboniferous age occur. 



First of all, we may give a complete list of the fishes which have hitherto been 

 found at this locality, indicating also the respective beds in which they have 

 occurred.

Here I may first draw attention to the fact that the list contains no representative 

 of the Elasmobranchii, with the exception of the peculiar group of Acanthodei. 



Theij I need hardly point out that the assemblage is one of Lower Carboniferous 

 estuarine forms. Not one of the named species can be noted as indicating an Upper 

 Carboniferous horizon. 



Among those named species we are struck with the presence of one rare form — 

 Wardiehthys cyclosoma — hitherto found with certainty only in one locality, and that 

 locality is Wardie, near Granton, from, which a division of the Calciferous Sandstone 

 series of the Edinburgh district, namely, the Wardie Shales, takes its name. 



In my paper " On the Distribution of Fossil Fish-remains in the Carboniferous 

 Rocks of the Edinburgh District," * I have given a list of the fossil fishes of Wardie 

 beach, which I reproduce here : — 



Pleuracanthus, sp. 

 Acanthodes sulcatus. 

 Megalicldhys, sp. 

 Rhizodus Hibberti. 

 Gonatodus punctatus. 

 Elonichthys Robisoni. 

 striatus. 



Rh adinichthys ornatissimus. 



,, carinatus. 



,, brevis. 



ferox. 

 Nematoptychius Greenocki. 

 Eurynotus crenatus. 

 Wardiehthys cyclosoma. 



Here we find that, in this list of fourteen species, eight out of the thirteen from
