This fauna, says Prof. Traquair, resembles tbut of the Russian De- 
vonian beds in Livonia. 
The Upper Old Red beds of Elgin have yielded tlie following species: 
Elasmobranchii. 
Selac}i a. 
Psammosteus taylori Trcj. Cosmacanthus malcolinsoni Ag. 
OSTRACODERMI. 
AiitiaivJia. 
Bothriolepis major Ag. Phyllolepis concentrica Ag. 
" eristata, sp. n. Conchodus ostreiformis McCoy. 
Teleostomi. 
Crossopteryyii. 
Holoptychius nobilissimus Ag. Polyplocodus sp V 
" giganteus Ag. Glyptopomus minor x\g. 
Dr. Traquair very justly remarks that the above fauna shows mani- 
fest indication of being later than that from Nairn. 
The overlying sandstones, which many years ago yielded the well 
known Telerpeton elgineiise, which was then and therefore supposed to 
be of Devonian age, are now assigned to the Trias in spite of their con- 
formity and the absence of clear evidence of a time-gap between them. 
These beds have now yielded thirteen traces of Reptilia, but no Bra- 
trachians. Besides the Telerpeton alluded to above, the most remarkable 
of these is the extraordinary Elginia mirabilis. "Nothing of this crea- 
ture is known as yet but the skull, and a most bizarre-looking skull it 
is, reminding us, as Mr. Newton observes, of the head of the American 
'horned' toad on a large scale." The paper is illustrated with nine ex- 
cellent plates of the fossils described. e. w. c.
