1889-90.] Dr Traquair on Fossil Dipnoi and Ganoidei. 385 
List of the Fossil Dipnoi and Ganoidei of Fife and the 
Lothians. By R. H. Traquair, M.D., F.R.S. 
(Read July 21, 1890.) 
No district of Great Britain is so rich in genera and species of 
Carboniferous Dipnoi and Ganoidei as that of Fife and the Lothians, 
and in the frequency of entire specimens of these fishes it is only 
approached by North Staffordshire. 
Another feature of the greatest geological interest is the abund- 
ance of fish remains in estuarine strata below the horizon of the 
Millstone grit, whereby a means of comparing the Ganoid fish 
faunae of the Upper and Lower divisions of the Carboniferous for- 
mation is afforded. Lower Carboniferous Ganoids and Dipnoans 
occur, it is true, in the western part of the great central Scottish 
carboniferous area, and a very remarkable assemblage of fishes of 
that period was discovered not many years ago in the district of 
Eskdale and Liddesdale in the south. But in England and Ireland 
and in other parts of the world generally, the Lower Carboniferous 
fish remains known to us are mainly those of marine Selachii, so 
that an especial interest attaches to the Carboniferous fish-fauna of 
Scotland, and particularly to that of the district with which the 
present list has to deal. 
A list of the fossil fishes of the Edinburgh district, compiled by 
the late Mr Salter, is given in the Memoir of the Geological Survey, 
explanatory of Sheet 32 (Scotland), and published in 1861. Since 
the appearance of this Memoir, now nearly thirty years ago, no 
collective list of the fossil fishes of this part of the country 
has been drawn up, though the amount of material amassed by the 
labours of many collectors has enormously increased during those 
years. Among those who have contributed, by their work in the 
field, to an augmentation of the material for a new and expanded 
list of the fossil fishes of this district, I may mention, besides Messrs 
Bennie and Macconochie, collectors to the Geological Survey of 
I Scotland, Mr W. Tait Kinnear, Mr W. Anderson, now of the Geo- 
logical Survey of New South Wales, Mr T. Stock, Mr James Kirkby, 
and the late Mr Robert Walker of St Andrews ; while I myself, 
during the past sixteen years, have been able to procure both for
