128 ; 
The following interesting Letter upon this subject I am indebted 
to Mr. Farey for permission to insert. 
“ Havine collected out and arranged my Notes and references 
to Authors, as to British Belemnites, with or without the Alveolé 
or series of cups belonging to their conical cavities, which Alveoli, 
when hitherto found separate, have been generally called Orihoce- 
ratites, by various Authors, (and are said by some recent Writers 
to characterize the Transition Rocks of Werner?) I find them 
referable to 20 different places in the British series of Strata; ex- 
tending from (1st) the London Clay above the Chalk, to (20th) 
the Limestone resting on Slate. 
“It is the 13th of these Eras, in which Belemnites existed during 
the deposition (and probably during the Creation also) of the 
Strata that now rise to the surface cr basset in the British Islands, 
that the very fine and perfect specimen lately found in Leicester- 
shire and Northamptonshire, by Mr. Benj. Bevan, the Engineer 
to the Grand Union Canal, of which specimens you lately shewed 
me drawings, are referable. 
“The Stratum to which I allude, is one of Blue Clay, situated 
in the upper part of what I have called the ‘‘Lias Clay,’ in my 
Derbyshire Report, vol. I, p. 114, or between the Northampton 
Freestone and the Blue Lias Limestone ; in the range of which Clay 
stratum across England, I have noted 9 localities of Belemnites, all 
probably of one species; the two first and most northern of these 
localities were known to Dr. Woodward, in the early part of the 
last century, as appears from his ‘Catalogue of the Fossils of 
England,” vol}. I, p. 108 and 110, and his specimens are yet pres 
served at Cambridge, I believe. 
“The 1st, from Ashby, E. N. E. of Market Harborough, North- 
amptonshire, is described as having two of the cups or chambers 
within the conic cavity of the Belemnite; the 2nd, from Great 
Bowden, N. E. of Market Harborough in Leicestershire, is men- 
tioned as having six cups within the Belemnite; 3rd, Mr. Bevan’s 
specimen, sent to Sir Joseph Banks in Dec. 1813, from Husband 
Bosworth Tunnel, N. W. of the village, in Leicestershire, at 12 
feet deep in the 5th shaft; several middling sized ones, in a layer 
in a lump of Clay, some of them crushed, and a large broken one 
containing six or seven cups; 4th, his fine specimen sent to Sir 
Joseph Banks in Feb. last, from 90 feet deep in Crick Tunnel, S. 
of the village, in Northamptonshire, (51 m. N. of Daventry), which 
you haye examined and drawn, and which is perhaps one of the most 
perfect specimens of the Belemnite and its Alveoli, that is known. 
“My 5th note relates to Belemnites found in this stratum near 
Cheltenham Town, Gloucestershire, which were in the possession 
of the late Fletcher Bullivant, Esq. of Stanton Ward in Derbyshire ; 
the 6th, at Frocester Hill, W. of Stroud in Gloucestershire, of 
which Mr. W. Smith has specimens; the 7th, near Lansdown, half 
a mile S. of Tog-Hill, N. of Bath in Gloucestershire, described in 
Mr. Walcott’s ‘‘ Petrifactions found near Bath,” p. 35, tab. 45, 
fig. B; but possibly this may belong to my 12th situation in the 
series? the 8th, E. of the town of Bath, according to Mr. Smith; 
and the 9th, at 'Tucking-mill in Monkton-Comb, S. E. of Bath in 
Somersetshire; large with their Alveoli, Mr. Smith. 
“¢[ would beg to recommend it to the Readers of the ‘* Mineral 
Conchology,”? and your Correspondents in general, to assist in 
increasing our list of these important Extraneous Fossils, by send. 
ing you as many perfect specimens as they can, out of Strata, whose 
exact situation and nature they can describe, along with them.
