384 THE FOSSILIFEROUS 
quarry near Dunse, he recognized his Irish Cyclopterus. As 
Mr. Stewart found the Scotch specimen associated with plates 
of Pterichthys major and scales of Holoptychius Nobilissimus,— 
two of the most characteristic ichthyolites of the Upper forma- 
tion, — there can be no hesitation in assigning to it its place in 
the scale ; and, of course, its position as an Upper Old Red 
fossil in Scotland may be held to determine that of the inter- 
esting group to which it is found to belong on the Irish side of 
the channel. 
With respect to the true place of that deposit of pale quart- 
zose sandstone which overlies the Upper Old Red in Moray, and 
has become famous in geology for its reptilian foot-tracks, its 
unique Sfagonolepis, and its well-marked curious little reptile 
the Zelerpeton Elginense, we are not yet provided with any 
determining evidence. No species common to the Upper Old 
Red and this rock has yet been discovered in either deposit. 
Mr. Patrick Duff, to whose labors we owe both the Stagono- 
lepis and the Telerpeton, is in possession (with the exception of 
the reptilian foot-prints detected by Captain Brickendon) of all 
the few fossils found in the superior rock, and of a very ample 
collection of those of the underlying one; but I have seen 
nothing in the two sets in the least resembling each other. 
The late Dr. Mantell supposed, indeed, he had traced a con- 
siderable resemblance between the scales of Stagonolepis and 
those of a ganoid of Dura Den,—the Glyptopomus. They bear, 
however, a much closer resemblance to the scales of the JZys- 
triosaurus Muenstere, a reptile of the Lias of Munich, ef which 
I exhibited a good print to this Society about three years 
ago, the use of which I owed to the kindness of Sir Charles 
Lyell. When visiting a quarry in this northern deposit sev- 
eral years since, I was informed by the workmen that they 
frequently came upon foot-tracks like those found by Captain 
Brickendon. The only other remains of the deposit is that of
