152 Field Meetings, 1909. 
study ground which fifty years ago was one of the richest in 
Lincolnshire—the GAINSBOROUGH DISTRICT—-where 
the great Copper Butterfly was wont to disport itself in 
abundance. In more recent years the ground has been drained 
and the growth of the woods has brought about a complete 
change in the landscape, consequently in the flora and fauna of 
the area, and the great Copper and other rarities are now extinct. 
Morton Carrs was reached in good time and the work of 
recording commenced. The nature of the soil was unfavourable 
for land shells, but the ditches yielded various species, most of 
them records for the district. 
The report on the Lepidoptera by Mr. G. W. Mason is as

Bupalus piniaria (common round Peacock’s Hole, two females 
being taken, a somewhat rare occurrence), Therva~ vanata,

After the meeting, Mr. F. Baines of Gainsborough, exhibited 
at the White Hart Hotel, several rare Butterflies, including 
Polyommatus dispar, the extinct Large Copper, which were taken 
by Mr. Forrington very many years ago at Morton Carr. He 
told the members present that Mr. Forrington had taken several 
specimens there in the lane by the side of the Wood over the 
drain. He also exhibited two Large Coppers, male and female, 
taken by the late Rev. K. J. Miller, Walkeringham, which 
would probably be taken outside the County of Lincoln. He
