Lias, Lyme Regis. 
Coprolites of both Fishes and Saurians have been obtained.* 
The larger coprolites of Saurians contain fish-scales, bones of 
small Saurians, and occasionally water-worn pebbles. f 
Among the Crustacea we find Scapheus (Fig. 38), a genus 
confined to the Lias, and Eryon which appears in this country for 
the first time. Foramimfera seem to be more abundant than in 
other divisions of the Lias. 
Among the Mollusca Ammonites and Belemnites appear, for 
they are not known in the Khpetic Beds of this country. Gaster- 
opods are represented by many genera, including Ambcrleyu 
(JEucyclus}, Cerithium, Chcmnitzia,Cryptcenia, Pitonnillus, Pleuro- 
tomaria, Trochus, Turbo, &c. Dentalium also occurs. 
With regard to the distribution of the fossils of the Lower 
Lias, it will be found that the local abundance of certain genera and
