xviii Proceedings. 



Mr. A. Warner exhibited and described Suffolk's new collecting 

 bottle, which is made with flat polished sides, and of such a 

 thickness that it can be placed on the stage of the microscope 

 and the contents viewed with a low power. 



Mr. Crowley exhibited a fine series of Attacus Atlas and other 

 moths, bred bj' himself. 



A discussion followed, on the entomological characteristics of 

 the year, in which many members took part, and it appeared 

 that the death's-head moth [Acherontia Atropos) had been unusually 

 abundant, both in the neighbourhood of Croydon and elsewhere. 

 Several captures of Sphinx ConvolvuH were also mentioned, and 

 Mr. Low Sarjeant exhibited and distributed a large number of 

 fine larvfe of Sphinx Ut/itstri (the privet hawk). 



The President exhibited a series of dried specimens of rare 

 plants, collected this summer among the Norfolk Broads, and 

 briefly described the physical features of this interesting district, 

 with its long navigable waterways, widening at short intervals 

 into lake-like expansions, some of them of large area, locally 

 known as Broads, so rich in birds, insects and plants. 



Amongst the plants I exhibited the most interesting were (1) 

 Senecio palmtris, a very handsome composite plant, apparently 

 rapidly approaching extinction. (2) Lipairis I.ceselii, the fen 

 orchis, a very rare plant, and interesting from the fact that it 

 was for many years lost to view and considered to be extinct, 

 but was refound in several localities in the fens of Cambridge- 

 shire, Norfolk and Suffolk about three or four years ago. (3) 

 Naias marina, the new British water-plant discovered by Mr. 

 Bennett in 1884, and happily now found by me in a second 

 locality in East Norfolk. (4) Potamof/eton trichioides, a very rare 

 pond-weed, which I found in an entirely new locality considerably 

 north and east of previously recorded stations. 



At the sixtli meeting, held Oct. 14th, Mr. Lovett read an 

 excellent paper on " The Glacial Deposits and other interesting 

 geological features of North Yorkshire," specially referring to 

 the ancient moraines of the Yorkshire dales, which often give 

 rise to lakes and tarns by blocking up the valleys, and to the 

 great deposits of glacial clay which overlies so large an area of 

 the east coast of Yorkshire and Durham (see Tkans., art. 53). A 

 fine series of scratched boulders illustrated the paper. 



A very interesting discussion followed (in which many mem- 

 bers took part) on the formation and motion of modern glaciers, 

 as illustrating the history of the ancient ones, and their im- 

 portant influence and that of the glacial period generally on the 

 present physical features of the country. 



A beautiful series of varieties of Limncra )iere(jra (the common 

 pond snail), including reversed and other monstrous forms, were 

 shown by Mr. McKean, and in the discussion which followed it
