Tue Committee report that the work during the past twelve months has 
been proceeding on the same lines as before. The reports from the 
specialists to whom the Eccup collection has been referred are not yet 
complete. Reports on special districts have been received from Dr. 
Wheelton Hind and Mr. G. H. Morton ; the latter hopes to report more 
fully later on. These reports are appended. The recent evidence 
obtained does not seem to afford any assistance in the selection of zone 
fossils capable of being used outside the special districts to which they 
were first found applicable. Thus, Chonetes papillionacea, a species charac- 
teristic of the Lower Scar Limestone of Westmoreland and Yorkshire, has 
recently been reported by Dr. Hind from the Upper part of the Carboni- 
ferous Limestone of the Congleton district in Cheshire ; while Mr. Morton 
finds that several common species, previously considered to be characteristic 
of the upper and middle subdivisions of the Carboniferous Limestone in the 
west of the country, occur in Anglesey and along the Menai Strait in 
the lower division. 
Owing to constant absence from England, Mr. Garwood has with 
regret been obliged to resign the office of Secretary tothe Committee. The 
Committee are, however, glad to state that Dr. Wheelton Hind has under- 
taken to transact the business of the Committee in future, if they are 
re-appointed. 
The Committee have been unable to carry out any further exploration 
during the year, and have therefore not drawn any of the money granted 
by the Association at the last meeting.

Yorkshire, Lancashire, Cheshire, Derbyshire, and Statiordshire, into two 
groups only—Upper and Lower.
