LOWER LIAS: BARROW-ON-SOAR. 169 
the cutting .near Rotherby, north-east of Brooksby railway- 
station. 
The principal sections are those in the quarries near Barrow-on- 
Soar, where the beds shown are as follows : 
FT. IN. FT. IN. 
Blue and brown clay and pyritic shale, 
with Ammonites catenatus - -50tol50 
Thin layer of stone. Lima gigantea, Grypheea~\ 
Lower Lias. arcuatu - - > 15 
Zones of f Grey and blue shaly clay - J 
Ammonites \ Limestone " Roof Bed," known also as Rammell 
angulatus ] or Rummels, with Am. planorbis and Lima 
and A. gigantea - - - 1 
planorbis. Shale .... 4 
Six or seven even " floors " of limestone and clay - 10 
Shale - 70 
[ Limestone " White Hurls " - 1 
A few more " floors " are worked in places, sometimes in the open and 
sometimes by shafts and drifts carried beneath the Roof Bed. The depth from 
the Rammell to the White Stone (top of Rhaetic Beds) is said to be 29 feet, and 
the thickness of the stone-beds that are worked is from 21 to 25 feet, including 
shales. 
Some of the bands have been employed for paving and other purposes, but 
much of the stone is very shaly and after exposure it flakes up. It is mainly 
worked for the Blue Lias Lime and Cement, manufactured by John Ellis and 
Company. 
The beds shown belong mostly to the zone of Ammonites plan- 
orbis, but the top clays and shales, which in places attain a 
thickness of about 80 feet, have been designated by Mr. Quilter 
the zone or sub- zone of Ammonites catenatus* This Ammonite 
is locally found in some abundance ; it was however regarded by 
Prof. Juddf as a variety of A. angulatus, and is no doubt an 
intermediate form, sufficiently pronounced however to be worthy 
of local distinction. Mr. Quilter regards the form as intermediate 
between A. planorbis and A. angulatus. 
A, catenatus is recorded by Mr. J. D. PaulJ from beds near 
Scraptoft and Thurnby, and it has been found with A. Johnstoni 
at the Spinney Hills, Leicester. 
Beds belonging to the zone of A. angulatus have been observed 
near Sileby by Mr. Quilter, and also in the railway-cutting on the 
Uppingham road, near Leicester. 
A boring near Evingfcon proved 186 feet of Lower Lias, 
including the beds from the base up to the zone of A. Bucklandi. 
At Crown Hill, north-west of Evington, nearly 50 feet of 
limestones and clays belonging to the zone of A. Bucklandi have 
been opened up. Mr. Quilter records A. Charmassei and other 
fossils from this locality. || 
In an easterly direction the beds are represented mainly by 
blue clays, with numerous scattered specimens of Gryph&a
