168 THE ' KELLOWAY EOCK ' OF SCARBOROUGH. [June I913, 



the Society was greatly indebted to the Author for his table of zones, 

 which indicated how the terms Callovian arid Oxfordian, or 

 preferably Divesian, might profitably be employed. His classi- 

 fication was not the orthodox one, but it rested on a sound 

 palseontological basis. 



Dr. A. M. Davies said that those geologists who were interested 

 in the Upper Jurassic strata should rejoice in the knowledge that 

 the Author was turning his attention to the zoning of those rocks. 

 It was certain that the number of Upper Jurassic zones would 

 have to be increased. 



The Presipexx (Dr. A. Strahast) reminded the meeting that the 

 relations of the Kellaways Kock of Yorkshire to the Oxford Clay, 

 and the fact that it was not strictly correlative with the Kellaways 

 Eock of "Wiltshire, had been pointed out by the late Mr. Hudleston 

 many years ago. BZe enquired whether it was contemplated that 

 the misspelling 'Kelloway' could or ought to be perpetuated. 

 The phenomena described under the names of cyclical and trans- 

 versal homoeomorphy appeared to be of great interest and to 

 deserve close scrutiny. 



The Author, in reply, remarked that the spelling 'Kelloway 

 Kock' was not his, and he had merely adopted a suggestion made, 

 he believed in the first place, by the late Mr. Hudleston, to keep 

 'Kelloway Eock' for the Yorkshire bed and 'Kellaways 

 Kock' for the more limited Wiltshire stratum, as a temporary 

 measure. In conclusion, he heartily thanked the Fellows for their 

 kind reception of his paper.
