label attached reads, ‘Footsteps of Labyrinthodon, Upper Keuper, 
Shrewley, presented by Hugh E. Strickland, Esq., F.G.S.’ The prints 
are, however, decidedly Rhynchosauroid in form. There do not seem to 
be quite similar prints on any of the other slabs from Shrewley.! 
The most common is another Rhynchosauroid form which is distin- 
guished from the foregoing by the absence of webbing and by the club- 
shaped digits, which show no trace of the presence of a nail. The digits 
are narrow at the proximal joint and gradually widen towards the distal 
end, where they are clearly rounded off. They are of the same propor- 
tional lengths as those of the other Rhynchosauroids, are moderately diver- 
gent, and the print of the fifth digit is only occasionally shown. In one 
case it is distinctly marked on both pes and manus. The other digits, 
I-IV., are usually fairly marked. This form will be referred to as D 6 ; 
it is a distinctly Shrewley form. Several examples are on small pieces of 
stone in one of the upright cases, and are described as Labyrinthodon on 
the labels. There are a pair of slabs, relief and impression, on the wall, 
with traces of two pairs of feet of this form on a rippled surface. These are 
also labelled as ‘ Labyrinthodon.’ (These are just to the left of the slab 
next to be described.) The slabs are about 8 inches across. 
Another, immediately to the left of the Murchison and Strickland 
slabs, measures about 15 inches and 13 inches, and shows a number of im- 
pressions on a rippied surface of fine white sandstone. It is labelled

There are portions of the surface of two layers, with footprints on 
each. The upper one is very thin, and the ripples are continuous on each. 
The ripples are much flattened, and it is doubtful if they are actual rippie 
marks, or if they may not have been due to other causes. They, however, 
do not interfere with the definition of the footprints, which apparently 
were made subsequently. 
The footprints are decidedly Rhynchosauroid, and are mostly D 1, 
Besides footprints there are what appear to be the tracks of Gasteropods, 
but might possibly be due to the tails of reptiles, though no connection 
with the footprints is apparent, as was the case in the slab described 
above. Altogether this slab is a most interesting one, and will repay 
further study and comparison with others of the same character in the 
collection. 
To the left of this is a large slab showing a series of prints of 
Cheirotheroid character. Unfortunately they are very imperfect, only 
the termination of three or four digits being recognisable on each foot. 
The breadth of the print is 6 inches; the length is not determinable. It 
is very uncertain whether very indistinct markings a little in advance of 
the more distinct prints represent the forefeet, but they possibly do. The 
Cheirotheroid prints usually are found in linear arrangement, the left 
' There is a slab of similar stone, in a very dark corner and clese to the ceiling, 
with imperfect impressions of somewhat the same form as the Murchison-Strickland 
slab, It hardly corresponds sufficiently to be the counterpart, which, moreover, in 
the original paper is said to have been deposited in the Museum of the Geological 
eet. The present position of this slab renders a careful examination very 
ifficult.
