Third Report of the Committee, consisting of Dr. Henry Wood- 

 ward [Chairman), Rev. G. F. Whidborne, Messrs. R, Kidston, 

 J. E. Marr, and A. S. Woodward (Secretary), to consider the 

 best methods^ for the Registration of the Type Specimens of 

 British Fossils. (Draiun up by A. S. Woodward.) 



Thr Committee have to report j^radaal progress in the registration of the 

 type specimens of British fossils, but regret that it is still impossible to 

 begin the tabulation of the results. Several important lists have been 

 received daring the year, and the printed catalogues of the collections at 

 ' Cambridge (Woodwardian Museum), Bath, and Brighton, referred to in 

 the last report, have now been issued. The lists, already at the disposal 

 of the Committee, are enumerated below, and a special effort will shortly 

 be made to obtain the remainder. The Keeper of the Department of 

 Geology in the British Museum is making arrangements for the cata- 

 loguing of the types in the national collection, and when this task is 

 completed the Committee will be the better able to consider the most 

 satisfactory method of dealing with the wliole of the material.
