Introduction. 



In the Supplement to the British Jurassic and Triassic 

 Brachiopoda by Thomas Davidson (Vol. IV., p. 230) is 

 set out a Hst of 33 species collected by Dr P. Smithe from 

 the Lias of Churchdown — that term denoting all the strata 

 from the zone of Am. opalinus down to the base of the 

 Lower Lias, inclusive. 



In a paper read before this Club in 1889,* S. S. Buckman 

 enumerated 34 species of Brachiopoda from the Inferior 

 Oolite of the Cotteswolds, the term in that case com- 

 prising the strata from the Clypeus Grit to the base of the 

 Pea Grit series, inclusive. In another paper read before 

 the Geological Society in 1895, which is printed in the 

 Quarterly Journal for that year (Vol. LL, p. 388) he in- 

 creases the number to some 53 or 54 forms. The list, 

 however, comprises a good many which are referred to 

 merely by the generic appellation. 



Taking these figures as representing at the time of 

 l)ublication the sum of the recognized forms of Cotteswold 



* Publislied in the Proceedings, Vol. IX., p. 374.
