Extract

The presence of Zieten's type-specimen of Ammonites calcar in the British Museum (Natural History) among some fossils which were bought of Dr. Bruckmann naturally suggested an examination of the other fossil Cephalopoda obtained from the same source, in the hope of finding other type-specimens. Thus far, the result of this examination has been the discovery of two more of Zieten's types; these are the type-specimens of (i) Ammonites polygonius and (ii) Ammonites discoides.
