ON THE SPECIES OF BRACHIOPODA THAT OCCUE 

 IN THE INFEEIOE OOLITE AT BEADFOED ABBAS 

 AND ITS VICINITY. 



(BY THOMAS DAVIDSON, ESQ., F.E.S., F.G.S., &c.) 



At the request of Professor Buckman and Mr. Darell Stephens 

 I have studied with all possible attention between eight and 

 nine hundred specimens of Brachiopoda from the Inferior Oolite 

 that had been collected by them and Mr. J. F. Walker at 

 Bradford Abbas, Halfway House, Crewkerne Station, Milborne 

 Wick, Haselbury, Broadwinsor and Bridport ; localities situated 

 partly in Dorsetshire, and partly in Somersetshire, at distances 

 varying from four to sixteen miles from Bradford Abbas. 

 Several of these localities are immensely rich in species and 

 specimens, which are met with in an excellent state of preserva- 

 tion. Mr. Darell Stephens alone forwarded for my inspection 

 upwards of seven hundred specimens. I have much pleasure in 

 laying before the Society the results of my examination, as well 

 as figures of each of the species that have been obtained from 

 the above-named localities. Yeovil is situated at about two 

 miles distance from Bradford Abbas, and has often been quoted 

 as a spot whence Inferior Oolite Brachiopoda have been obtained, 

 but I am informed by both Professor Buckman and Mr. Darell 

 Stephens that there is no Inferior Oolite at Yeovil itself, the Yeo, 

 thence to Bridgwater, running along a bed of Lower Lias shale. 

 Therefore, instead of Yeovil, Professor Morris, myself, and 

 others should have said, near Yeovil, the Inferior Oolite occur- 

 ring at Bradford Abbas, Dorset, a locality not far distant. 



It will not be necessary in this communication to give com- 

 plete descriptions of all th.3 species, as they will be found in my 

 monograph on British Fossil Brachiopoda, to which the reader 

 is referred.
