teeth of Acrodus minimus, Saurichthys acuminatus, and of 
an actinoptergian fish, which Mr Montagu Browne, F.G.S., 
considers may be a Gyrolefis, are of the most frequent 
occurrence. The Rev W. S. Symonds’ mentioned that 
the teeth of Ceratodus had been procured from the Bone- 
bed at this locality, but the record seems to require further 
confirmation before it can be accepted.* Coprolites are 
not numerous, the largest I recorded was two inches long 
and half inch in diameter. It was embedded in a greenish, 
pyritic, sandstone matrix. The surface of the Bone-bed, 
and especially that of the sandstone-equivalent, often 
exhibits remarkable impressions, protuberances, tracks and 
ripple-marks. A thin, but continuous clayey deposit, of 
variable thickness separates the lowest and most ossiferous 
layer of the Bone-bed from a series of I to 4 grey sand- 
stone bands: the latter slightly calcareous, and collectively 
from I to 2 inches in thickness, constituting the upper 
part. The surfaces of these layers exhibit phenomena 
similar to the lower portion of the Bone-bed. The tracks 
may be due to annelids, but with the exception of these 
and the ripple-marks, of which there are two sets oblique 
to each other, the other phenomena are difficult of inter- 
pretation. Strickland noted four kinds of markings. 
Black shales, 9 to 12 inches thick, separate the Bone- 
bed from two hard, pyritic, micaceous, calcareous sand- 
stone bands, which are divided by a black clayey deposit. 
Sometimes more than two bands are present, and then 
the clay partings are thinner. In addition to an abundance 
of selenite crystals, the lower of these two bands is

. the railway cutting at Glover’s Hill, Ripple, in the Upper Keuper Sandstone. The 
specimen named Ceratodus euisstmus is in the British Museum. Vide “ Monograph of
