AMMONITES Taylori. 
TAB. DXIV.—fig. 1. 
Spec. Cuar. Discoid, radiated ; inner whorls ex- 
posed ; radii about 12, with one large spini- 
form tubercle upon each side of the front, and 
one or two slight elevations on the rounded 
sides of the whorls ; aperture nearly round. 
Averture rather transverse, not quite one-third of the 
diameter of the shell long: there are about three whorls ; 
the inner ones are small, but almost wholly exposed to 
view. 
Found in a water-worn mass of indurated Clay ap- 
proaching Ironstone, and containing Blende, in Hap- 
pisbury Cliff, where it was probably alluvial. 
For the use of the specimen I am indebted to R. Tay- 
lor, Esq., of Norwich, whose assiduity in collecting and 
drawing the fossils of the Cotswold Hills, and other 
Geological researches, have induced me to yield to 
friendly inclinations in commemorating his name.
