Ur. R. H. Traquair on Fossil Fishes 
any other fish-bearing schist with which I am acquainted, 
and to observe that they were finding their way into collec- 
tions, even in London, though without the precise locality 
being indicated. In the autumn of 1889 Achanarras w r as 
visited by the officers of the Geological Survey of Scotland, 
and I have received the kind permission of the Director- 
General to exatnine a collection of fishes from it, presented 
to the Survey by the Thurso Flagstone Quarrying Company, 
W'ho are the lessees of the quarry. It was not, however, until 
the month of August of the present year that I had myself 
the opportunity of visiting the spot. On this occasion, when 
on a visit to Mr. Gunn and his family at Dale, which is 
about two miles from Achanarras, I spent several days 
exploring the debris of the quarry, and, besides many speci- 
mens of the u baby Coccosteus 99 ( Palceospondylus Gunnii ), 
Mr. Gunn and I discovered three examples of Diplacanthus 
striatus , a species rare in the Caithness beds, besides several 
specimens ot a species of Mesacanthus and other fishes. Shortly 
afterwards I received, for the Natural History Department of 
the Museum of Science and Art, a large donation of Achan- 
arras fishes from the Thurso Flagstone Quarrying Company. 
I must also acknowledge my indebtedness for material to 
Mr. James Reid, of Allan House, Blairgowrie, who for some 
years back has greatly interested himself in collecting the 
fossil fishes and plants of the Old Red Sandstone, and to 
Mr. Munro, of Achanarras Farm ; and I have carefully looked 
through the collection made by Mr. Edwards, of Leigh, near 
Manchester, at present deposited in the museum at Owens 
College.
