is still doubtfully distinct from the Botliriolepis ornata of Eu- 

 rope : the fragments of a Diplacanthus obtained by Mr. Foord 

 have apparently much the same characters as the D. striatus 

 of Agassiz, and the genus Plianeropleuron can now be shown to 

 occur in the Devonian rocks of Canada as well as in those of 

 Scotland. Eusthenopteron has at least some features in common 

 with Tristicliopterus : one species of Glyptolepis from Scaumenac 

 Bay seems to be identical with the G. microlepidotus of Agassiz, 

 from Lethen Bar, while the other bears a general resemblance 

 to the G. leptopterus of the same author ; and, lastly, the Cheiro- 

 lepis Canadensis here described is certainly closely allied to two 

 Scotch wspecies. 



The existence of fossil plants, as well as of fish remains, in 

 the Devonian shales and sandstones of Scaumenac Bay was no- 

 ticed by Dr. Gesner in 1842, and from these rocks Mr. Foord 

 also obtained a series of specimens of four species of ferns, 

 which will be found described on pages 8-11 of the present 

 number of this journal. 



These deposii:s may have been of fresh water or estuarine 

 origin, for no traces of any marine invertebrata have yet been 

 detected in them, and the fossil fishes which they contain are in- 

 variably found associated with land plants.
