_ VOL. XIV. (2) RHATIC ROCKS hg 
the remanié-bed and the planorbis strata to the Keuper 
Marls could not be accurately ascertained: it suggests a 
fault. The remanié-bed attains a thickness of 5 inches, 
one portion is a fissile argillaceous limestone, the other is 
mainly composed of shell debris. The former in its lithic 
structure resembles the Pseudomonotis-bed, and contains 
that lamellibranch; the latter yields Modiola minima, 
Ostrea Sp. Pseudomonotis decussata, and scales of 
Gyrolepis : there are also angular to subangular inclusions 
of a brownish rock. On the whole, the specimens of 
Pseudomonotis appear to be too well preserved to be 
remanie. . 
A detailed examination of the area between the latter 
section and Hasfield revealed no definite section: all the 
lanes which traversed the escarpment were examined, but 
the results obtained demonstrated only a remarkable 
proximity of the Upper Keuper to the Lower Lias. In 
the escarpment near the house known as “‘ Foscomb,” and 
in the numerous trenches passing through Corse Wood 
and draining the summit of the hill of that name, there is 
evidence of the greyish-green marls of the Upper Keuper. 
At the same localities, but at a slightly higher contour, 
portions of a blue shelly rock, apparently containing 
fragments of a brown limestone were found. One piece 
contained small fragments of a green rock (Upper Keuper 
marl ?), Ostrea, Pseudomonotis decussata, fish scales and 
a coral were recognised. The shelly limestone resembles 
the remani¢ bed of Lassington. The only useful exposure 
in this district is in a road-cutting near “The Hill,” 
Hasfield. Doubtless it is the one referred to by the Rev. 
P. B. Brodie. Concerning it he observed’ “ There appear 
to be two beds of ‘Tnsect-limestone’ lying within a few 
feet of each other, which present a large assemblage of
