in between them. The top-portion of the Clypeus-Gxii was 
very barren of fossils, and the conspicuous large oolite-granules 
were sparsely distributed (spec. 46). In the Upper Trigonia- 
Grit, between 6 ins. and 2 ft. from the top specimens of Tri- 
gonia costata J. Sow. (spec. 47) were abundant. Acanthothyris 
spinosa (Linn.) was found at 4 ins. from the bottom, above the 
shaly rock (476;) with pebbles. 
The Upper Trigonia-Gni rests directly on the Lower 
Freestone, the top-stratum of which was noticeably bored 
(Fig. i). The Lower Freestone is of very uniform texture 
and for the most part obliquely-bedded (spec. 48a). In the 
bottom I ft. 6 ins., however, remains of pentacrinoids were 
most abundant (spec. 48^). The Lower Freestone is thicker 
at Kemble than here — 43 ft. 6 ins., as against 19 ft. 
The Pea-Grit is of much the same thickness as at Kemble — 
36 ft. 10 ins., as against 35 ft. 6 ins. (at Kemble). 
The top 3 ft. of rock had the appearance of a bluish-grey 
mudstone, practically devoid of pisolites, but the rest of 
the rock — right down to the Lower Limestone — was crowded 
with pisolites and quite typical. Black shaly matter occurred 
here and there and represents the soft yellow shaly matter seen 
in quarry faces — for example, at Crickley Hill. 
The change from the pisolite to the oolitic limestone of 
the Lower Limestone was sudden, and therefore very noticeable. 
The Lower Limestone was a bluish-grey oolite with irregular, 
coarser-grained streaks, which, on closer inspection, proved to 
owe their character to innumerable fragments of isocrinoids. 
Sandy layers occur in the lower portion and suggest the in- 
coming of Sassww-Bed conditions, but the oolitic structure 
was predominant to the very base (spec. 50), and there was no 
evidence for Sczss^^m-Beds. 
At Kemble the Pea-Grit rests directly on the Cephalopoda- 
Bed ; here the Lower Limestone rests on that stratum. No 
Sc^'sswm-Beds intervene. 
Upper Lias. — The Cephalopoda-Bed here is a hard 
brownish limestone, with brown, often pyritic granules. It 
is a pretty rock, and very similar to that of layer b of the Red
