IN THE CARBONIFEROUS ROCKS OF THE EDINBURGH DISTRICT. 703 



Upper Carboniferous. 



The list of fishes from the Upper Carboniferous strata of the Edinburgh district is as 

 yet short, seeing that it contains only nineteen species, but as not one of these can 

 safely be identified as occurring in the rocks below, we have evidently got into quite a 

 new ichthyological stage. 



This is, however, the same fish-fauna as that of the Upper Carboniferous of the rest 

 of Britain, as will clearly be seen by comparing the following lists. 



First, as to the West of Scotland, where the rocks of this division occupy a much 

 greater area than in the East, and are more extensively worked for coal. I extract the 

 following Upper Carboniferous species from my list of the Carboniferous Fishes of the 

 West of Scotland, published in the British Association Handbook, Glasgow, 1901. 



Diplodus gibbosus, Ag. Acanthodopsis Wardi, H. and Atth. 



Pleuracanthus Icevissimus, Ag. Megalichthys Hihbcrti, Ag. 



,, cylindricus (Ag.). „ coccolepis, Young. 



„ robustus, Duvis. „ vntermedivs i A. S. Woodward. 



,, alatvs, Davis. „ pygmceus, Traq. 



„ denticidatus, Davis. Rhizodopsis sauroides (Williamson). 



„ Thomsoni, Davis. Strepsodus sauroides (Binney). 



„ tenuis, Davis. „ sulcidens (Atthey). 



Janassa linguaiformis, Atthey. Ccelaca?ithus elegans, Newb. 



Ctenoptychius apicalis, Ag. Ctenodus cristatus, Ag. 



Callopristodus pectinatus (Ag.). Sagcnodus inequalis, Owen. 



Helodus simplex, Ag Elonichthys Egertoni (Egert.) 

 Pleuroplax Rankinci (Ag.) „ Aitkeni, Traq. 



„ Atthey i (Barkas). Acrolepis Hopkinsi (M'Coy). 



Sphenacanthus hybodoides (Egert.). Rhadinichthys Grossarti, Traq. 

 Euctenius unilateralis (Barkas). „ Monensis (Egert.). 



Lepraeanthus Colei, Owen. Cheirodus granulosus (Young). 



Gyracanthus formosus, Ag. Mesolepis, sp. 



Bertacanthus striatus, Traq. Platysomus parvulus, Young. 



„ tuberctdatus, Traq. „ Forsteri, H. and Atthey. 



Acanthodes Wardi, Egert. 



Here we have forty-one species, including every one of those which occur in the 

 Edinburgh district. 



Passing next to the English Upper Carboniferous, we first note the fish-remains 



from the roof-shale of the Low Main seam at Newsham, near Newcastle-on-Tyne, 



belonging to the Lower Coal Measures, and which yielded to the labours of the late 



Messrs Hancock and Atthey quite an unusual number of species to come from a single 



bed. The following list of the species in the Atthey collection, now in the Museum at 



Newcastle, was made by myself a few years ago with the permission of the late Mr 



Howse, then curator of that museum : — 



Pleuracanthus lazvissimus. Gyracanthus formosus. 



„ cylindricus. Sphenacanthus hybodoides. 



„ robustus. Janassa lingtiwformis. 



„ denticidatus. Callopristodus pectinatus. 



Diplodus gibbosus. Pleuroplax Rankinei.
