8 Rose—Valley-Deposits of the Nar. 
I conclude from such evidence as has hitherto been submitted 
to me, and for which I heartily thank Mr. Lee, that the An- 
thrakerpeton from the Welsh Coal belonged to that low, pro- 
bably primitive, air-breathing type, which, with developmental 
conditions of the bones like those in some Fishes, and very 
common in Devonian Fishes, showed forms of the skeleton more 
resembling those in Saurian Reptiles than are attained by any of 
the more specialized Batrachian air-breathers of the present day. 
I propose, in reference to the characteristic density and 
thickness of the walls of almost all the long bones hitherto ob- 
tained of this air-breather, to name it_Anthrakerpeton crassosteum. 
EXPLANATION OF THE PLATES.

scutules. 
. Portion of Coal-shale with portions of two ribs. 
. Portion of Coal-shale with part of the cranium and of a long and 
slender bone. 
. Smaller portion of a similar bone on the opposite side of the shale. 
. Portion of shale with parts of two slender, straight, and pointed 
benes. 
. Portion of a symmetrical, grooved, flat bone; gw. from naso-palatine 
cavity ?

Pruare II, 
. Transverse section of a long bone; magnified 50 diameters. 
. Section of part of the bone in the direction of the long axis of the 
bone-cells ; magnified 222 diameters. 
. Section of part of the bone near the central cavity, taken transversely 
to the long axis of the bone-cells. 
These sections were prepared, and the drawings of them made on stone, 
by Jonn Epwarp Luz, Hsq., F.G.S., the discoverer of this extinct Coal 
Reptile.

aN POST-TERTIARY deposit, under the above denomina- 
tion, hes upon the ‘ Drift’ in the valley through which 
the River Nar takes its course towards its junction with the 
Ouse at Lynn; the united streams terminating in the Wash, 
an estuary bounded by the shores of Norfolk and Lincolnshire. 
This Post-tertiary deposit I have traced along the valley 
from Narford to Watlington, a distance of about nine miles,
