Extract

The paucity of animal remains in the Coal-measures of Somerset has been recognized for many years. More recently Dr. H. Bolton has described fossils from various horizons in the coalfield, but his records relate chiefly to insects and marine fossils, while non-marine Lamellibranchs appear to be unusually rare at most horizons. A number of species of non-marine Lamellibranchs have been recorded by various authors, but in view of the wide interpretation formerly given to the various species, many of these records cannot be used for zonal purposes.

Surv., 1913–1914, pp. 100–1). Dr. F. L. Kitchin has kindly allowed us to examine the specimens referred to, which are in the collection of the Geological Survey (Pl. 1673). The material is badly preserved; it includes A. cf. phillipsii but we are not able to recognize A. tenuis or any other speciesGoogle Scholar.
