was coTerecl with Fullers'-Earth clay, from which were obtained Bhynchonctta 

 Smithi (25 to 30 specimens), Terebratula glohata, auctt. (the variety common at 

 ^. Midford [and Doulting]), Orni- 



thella ornitliocephala, Modiola 

 [ Volsetta] gibbosa, some fragment 

 of Ostrea sp., Holectypus hemi- 

 sphcericics, some indeterminable 

 specimens of lamellibranchs, a 

 gasteropocl (internal cast), and 

 pieces of beleinnites. On yet 

 another visit, this time in com- 

 pany with Dr. A. Vanghan,. 

 several more brachiopods were 

 found, a cast of a large Pkola- 

 domya, and an Ostrea acuminata. 

 The last fossil was found in situ 

 by Dr. Vaughan. It is also of 

 interest to know that, on this 

 occasion, we each found a small 

 specimen of an Aulacothyris of" 

 the same species as that which 

 occurs in the. clay that overlies 

 the top-beds of the Inferior 

 Oolite at Broadwindsor (Dorset). 

 ' At the time when Messrs. 

 Buckman & Wilson investiga- 

 ted this part of the hill quarrying- 

 operations had not been prose- 

 cuted sufficiently far back to re- 

 veal this pocket of Fullers' Earth 

 and other material. One may 

 say " other material" advisedly ; 

 for, scattered amongst the Ful- 

 lers' Earth, are blocks of lime- 

 stone of an earlier age than that 

 formation.' {In litt., February 

 25th, 1907.) 



I interpret the blocks of 

 limestone, of an earlier age 

 than the Fullers' Earth, as 

 belonging to the Doulting 

 Beds. They should be 

 searched carefully for the 

 little Anabacia of the Ana- 

 bacia-IAmestones. 



V. Conclusion. 



In this paper it has been' 

 shown that, in the Bath- 

 Doulting district, there is 

 no Inferior-Oolite deposit 

 of pre - Garantiance date. 

 Consequently, there is a 

 great non-sequence between 

 the Inferior Oolite and the 

 55 underlying beds. Expressed 



in terms of universal application, aD the Aalenian and Bajocian
