154 Mr. J. Lycett on the Fossil genus Isodonta. 
figured by Buvignier from the Department of the Meuse ; but 
‘tis desirable that additional British examples of this rare form 
should be examined. I need hardly suggest to you the expe- 
diency of making a rigorous search in the Cornbrash and the 
Kelloway rock of the vicinity of Cirencester ; and believe me to 
remain, dear Sir, 
Yours, &c., 
Joun Lycert.
