AMMONITES Bucklandi. 
TAB. CXXX. 
Spec. Char. Depressed, inner volutions exposed, 
with large obtuse radii ; back carinated, and a 
furrow on each side of the keel ; aperture 
quadrate. 
Volutions about five, their sides wholly exposed, the 
back flatfish, with two concentric grooves, and an inter- 
mediate keel ; the radii are swelled towards the back, 
over which they are suddenly reflected, and gradually 
lost, as in several other carinated Ammonites ; the keel 
is obtuse and entire. 
Found in the Blue Lias of Bath and the neighbour- 
hood, measuring from a foot to 21 inches or more in 
diameter, and rather remarkable for having frequently 
lost the inner whorls ; which circumstance, by a sort of 
friendly pun, has given rise to the name given it, in 
honour of a meritorious and enlightened Geologist, the 
Rev. W. Buckland, who having found a large specimen, 
was induced by his ardour to carry it himself, although 
of considerable weight, and being on horseback it was 
not the less inconvenient ; but the inner whorls being 
gone so as to allow his head and shoulder to pass 
through, he placed it as a French horn is sometimes 
carried, above one shoulder and under the other, and 
thus rode with his friendly companions, who amused him 
by dubbing him an Ammon Knight ; and thus the speci- 
men was secured, by diverting the tedious toil otherwise 
hardly to be borne. May his zeal for information always 
be rewarded : may his abilities continue to meet that 
attention they have hitherto so deservedly gained : may 
his horn be exalted with honour. 
Mr. B. lately found Ammonites striatus, tab. 53. f. 1. 
in the transition slate of Filliagh, near South-molton, 
Devonshire.
