3. ' An Earthquake Model.' By John William Evans, D.Sc, 

 LL.B., F.G.S. 



The President read the following communication received from 

 Mr. S. S. Buckman, F.G.S. : 



4 May 29th, 1910. 



' In my paper on " Certain Jurassic Species of Ammonites " (Quart. Journ. 

 Geol. Soc. vol. lxvi, 1910, p. 90) I proposed for a new genus the name Burtonia 

 (p. 97). With that kind helpfulness which is so distinctive of American scien- 

 tific workers. Dr. W. H. Dall writes to say that this name ie already in use — 

 by Bonaparte for a bird and by Bouvignat for a naiad. I therefore desire to 

 substitute the name Bredyia for Burtonia in my paper: Bredyia is from the 

 River Bred}' (pronounced Breedy, Briddy) which flows through Burton 

 Bradstock, and its name presumably furnishes the syllable Brad. I wish to 

 record my thanks to Dr. Dall for his kindness. 



' The opportunity may be taken to rectify a misprint : in p. 68, line 7 from 

 the top, for " striking " read " sticking." ' 



An earthquake model was exhibited by Dr. J. W. Evans, LL.B., 

 F*GvS., and Mr. F. J. Bakewell, in illustration of Dr. Evans's 

 paper.
