Norton there is a very similar nodular limestone bed 
above 7, and it is nearer to that bed than to 5 b, which is 
presumably the equivalent of a similarly distinguished 
stratum at Wainlode. At Coomb Hill there is no bed 
such as might represent 5 b above the nodular limestone, the 
next limestone stratum being the “stherza-bed. Vegetation 
has now almost obscured the Upper Rheetic strata, so that 
I have to accept Strickland’s measurements of the argilla- 
ceous deposits. Pieces of all the limestone bands were, 
however, procurable, and a considerable quantity of 
material has been examined. The /stherza-bed, according 
to Strickland, rests upon 14 feet of brown clay, the lower 
portion of which I was able to examine by a little excava- 
ting. The lowest portion—32 inches in thickness— 
is a black, coarsely laminated, slightly calcareous shale, 
with an intermittent sandstone band, the whole replete 
with lamellibranchs. The remaining 11 feet 4 inches of 
deposit, are pale greenish-yellow shales, coarsely laminated 
and marly. 
The pieces of the stheria-bed procured here were 
non-nodular, and had an irregular fracture. A portion of 
the bed showed Vazadita remains to be present, and 
associated with them were clusters of Astherz@—the latter 
not well preserved." Five feet of yellow clay are stated 
to separate the sthevza-and Pseudomonotis-beds. Numer- 
ous pieces of the light-grey fissile, Pseudomonotzs-bed, 
were found, and it proved to be considerably more fossili- 
ferous here than at Wainlode, especially as regards insect 
remains. Small specimens of JZodiola minima are com- 
mon ; Pseudomonotis decussata being of rarer occurrence. 
“Yellow clay” is the superincumbent deposit, and is 
doubtless the equivalent of the brown and grey shales of 
Wainlode, Westbury, etc. The thickness of the Upper 
t An excellent piece of this bed crowded with Zs¢he/7e is preserved in the Worcester 
Museum,
