188 SUPPLEMENTARY INDEX TO VOL. III. 
A continuation of the Table in p. 243 of Vol. II. ( which was brought down to 
Vol. III. p. 77 ); particularizing such species of SHELLS, as are in the 
present Volume, ref erred to more than one STRATUM , and are in the 
Index which follows, distinguished by the Greek Letters a. and ft, unless 
otherwise mentioned below :

In the present volume, 179 species of Shells are named, besides 13 
varieties, marked (5, of Shells belonging to the same Strata, with their 
relative Shells, marked a ; besides which, my recent investigations have 
led to the separation of 19 other varieties, on account of their belonging 
to differejjf Strata: making thus 198 species (or varieties) belonging to 
distinct Strata, and which I am inclined to wish, had as many distinct 
names assigned them. 
Doctor Tilloch, in the 46th and the 52d volumes of his Phil. Mag. did 
me the favour to print alphabetical tables, of the places which furnished 
the Fossil Shells, described in your two first volumes ; and I have pre- 
pared, and am now about to send to him, a like table of the places, Strata 
and Shells of the present volume ; — and wishing now again, success to 
Mineral Conciiology, I remain, Sir, your obedient humble servant,

* P.S . — Whilst my Son John F., assisted by his three younger Brothers, carried on 
under my roof, a professional concern, (that now Joseph F. pursues), which occasioned 
them to be far more extensively and widely known and corresponded with, than myself, 
1 avoided many mistakes, by an addition to my Name, which now, since each of my Sons 
has a separate Residence, has become unnecessary. 
Additional Localities of Shells described in this Work. 
Ammonites annulatus, tab. 222. — My a angulifera, tab. 224, /. 6 and 7. 
Thes§ have been found in Oolite at Sherborne in Dorsetshire, by Dr. 
W. Dansey, of Blandford. 
Avicula ineqnivalvis, tab. 244. — Robinhoods’ Bay, near Scarborough. 
Orthocera gigantea, tab. 246. — Red Limestone Quarries, at Castle Espy, 
near Comber, in the county of Down, Ireland, James Clealand, Esq. 
with the following observations from Dr. Macdonnell : “ The dip of 
“ the Graywacke on which the Comber Lime rests is generally 45° or 
“ upwards, sometimes vertical ; the direction of the Graywack6 is 
i( always NW. by W § W. by compass. The Limestone is in beds, from 
“ one to three feet thick, of which beds there are 15 or more, on the 
*' sea shore, and only a little inland on the south side of Newtown Laugh. 
u This body of Lime is always somewhat salmon-coloured, and is exactly 
“ similar, in its colour and dip, and in the petrifactions it contains, to 
“ the great body of Lime at Ardmagh. Its coralline contents are very 
“ numerous; among these I could often recognise the Basaltiform Ma- 
u dreporite : there are several large bivalves. Each stratum appears 
u to differ in some respects from the others, in texture, thickness, 
and fossils : they lie all strictly parallel, and never conformable with 
“ the Graywacke.”
