THE LIAS MARLSTONE OF LEICESTERSHIRE. 
The encrinital bands are generally found above the “jacks,” 
but at Holwell and also at Knipton and Branston near Belvoir 
they occur at the base of the ferruginous series. The base of 
the Maidstone can always be fixed by the band of pliosphatic 
concretions above referred to. Ammonites acutus and the 
other ammonites, A. spinatus only excepted, are never found 
except at the top, but so far these ammonites have only been 
found at one place, viz., Tilton. I append a list of the organic 
remains already known to occur in the Maidstone Bock of the 
Leicestershire district. The species from Tilton are placed 
in a separate column, from which it appears that a greater 
number of fossil forms have been found at that place than at 
all the other localities put together. Further search, especially 
in fresh exposures, will no doubt appreciably extend the list 
here given. 
In drawing up this list I have received very material 
assistance from Mr. T. Beesley, F.C.S., of Banbury, and also 
from Mr. H. E. Quilter, of Leicester, who has very kindly 
placed a number of his fossils at my disposal. I wish also to 
acknowledge the valuable information that has been at different 
times given me by Mr. H. W. Sadler, resident engineer for 
the new Eaton and Eastwell branches of the Great Northern 
Kailway, as to the character of the rocks met with on those 
lines; and also by Mr. W. Ingram, of Belvoir; Mr. H. A. 
Allport, of Barnsley; Mr. B. Dalgliesli, of Holwell; and Mr. 
E. E. Coke, of Nottingham, as to the history of the Leicester¬ 
shire ironstone industry.
