INTRODUCTION. 
I am indebted to the kindness of Professor Ramsay, Director-General, and 
of Professor GrIkiE, Director of the Scottish Branch of the Geological Survey 
of Great Britain, for the privilege of examining and describing a remarkable 
collection of fossil fish-remains from the Lower Carboniferous rocks (Calci- 
ferous Sandstone Series) of Eskdale and Liddesdale. Most of the specimens 
were collected by Mr Artuur. Macconocuig, one of the collectors attached to 
the Scottish Geological Survey ; and Mr Water Park of Brooklyn Cottage, 
Langholm, has also willingly co-operated in the search, so far as the district of 
Eskdale is concerned. I have myself also had the pleasure of twice visiting 
Eskdale, along with Mr Macconocuiz and Mr B. N. Peacu, and on these 
occasions I obtained a few specimens for my own collection. 
This collection is of the greatest possible interest, both from a geological 
and from a zoological point of view—both as opening up to us an almost 
entirely new Scottish Carboniferous fish-fauna, as well as from the purely 
zoological interest attaching to the structural peculiarities of many of the new 
forms themselves. My own business with these fossils is, of course, entirely as 
a zoologist. 
The fish-remains which have occurred in these strata are referable to the 
orders of Ganoidei, Dipnoi, and Selachii, of which only the first will be consi- 
dered in this instalment of the report, while a second part will be devoted to 
the enumeration and description of those belonging to the two remaining 
Orders. 
The following is a list of the genera and species of Ganoids which have
