A. opalinus. The bed with T. infra-oolitica, &c. is seen also 
in Crewkerne railway-cutting, and belongs to the zone of 
Ammonites opalinus.

At the base of the zone of A. Murchisonce there are some sandy 
limestones imperfectly oolitic in places, that have yielded A. 
Murchisonce, A. concavus (fine var.), A. Leckenbyi, and other 
fossils. Lithologically they form a passage between that zone 
and the underlying beds. 
Before passing on to more northerly regions it will be useful 
to give a list of the more abundant and important fossils of the 
South Dorset district. 
The specimens collected by myself are marked (W), and they were 
identified by Messrs. Sharman and Newton, who also named a number of 
specimens collected by Dr. M. Poignand (P). Other species are given on 
the authority of Mr. Hudleston (II), and Mr. Buckman (B), as noted in the 
first column. 
The particular zone of certain species from the iron-shot beds, is left 
uncertain.
