PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. 



are S. oxygona, Des., and 8. DeslongcJiampsii, Dav. The latter 

 very beautiful shell is particularly abundant, though it never 

 occurs with its valves united, and not often in very good condition. 

 Theciclium Bouchardii, the commonest Brachiopod in the Inferior 

 Oolite of Dundry, is equally plentiful in the Whatley Lias, and 

 reaches a good size for this genus. T. Moorei, Dav., T. granulosum, 

 Moore, and T. rusticum, Moore, occur with it, but are rare. 



The Bryozoa yield two genera — Berenicea and Neuropora. 



The Echinodermata, of which the bed is in great part composed, 

 yield the new genera Cotylederma and Plicatocrinus of Deslong- 

 champs, with several other genera. 



The following list contains a goodly series for so abnormal a 

 deposit : —

6. Mells Middle Lias and Coal. — In all the sections in which I 

 have recognized the Middle Lias in this district, the beds are those 

 containing Gryplicea cymhium, or G. Maccullocliii, and are there- 

 fore the very bottom of this formation, resting immediately upon 

 the Lower Lias. The Middle Lias of Ilminster, which is the 

 equivalent of that in Gloucestershire, and of the ironstones of York- 

 shire, is a much higher zone, and is well known by its Fecten cequi- 

 valvis, Ammonites margaritatus, A. sjpinatus, &c. The nearest point
