are a few of the more ordinary forms.
Of Pteropods and ordinary spiral shells, Conularia Sowerbyi is abundant enough, and of several varieties, and probably there is another species.
Murchisonia Lloydii, M. undata, M. balteata, M. articulata, and at least seven other species, chiefly from the limestone.
Euomphalus alatus, E. funatus, E. sculptus, E. discors, E. rugosus, E. carinatus, and two or three undescribed ones.
Cyclonema carinata, and E. corallii; Turbo cirrhosus?; Macrocheilus; Natica; Acroculia prototypa, and A. Haliotis, with many species as yet unnoticed of all these genera.
Lastly, there are several Cephalopodous shells, though most of these are among the rarer forms.
Orthoceras annulatum and its variety, O. fimbriatum, is most common.
Phragmoceras pyriforme occurs at Dudley, Lituites comu-arietis, and L. tortuosus are only occasionally met with.
There are several rarer fossils, which we can scarcely do more than notice here; among others, two species of Chiton; an Ischadites,
