reared in May last from ova obtained from a moth taken on the 

 occasion of the Society's field meeting at Beaconsfield on June 

 ^Oth, 1914. The larvse were fed almost entirely on the flowers of 

 an Alpine campanula (Campanula piisilla), a species often grown in 

 rock-gardens, apparently preferring it to any of the numerous other 

 wild or garden flowers with which they are usually associated. 



Mr. A. Sich exhibited the following four species of British slugs, 

 AgrioUmax arjrestis, Milax sowerbii, Avion hortensis, and Testacella 

 scutuliuii, and a series of coloured drawings of all the British species 

 of land slugs, executed by himself. He then read a paper entitled 

 " Limacology." (See p. 41.) 



In the ensuing discussion Mr. Priske stated that he had frequently 

 seen Testacella disgorge the worm it had just previously swallowed. 

 Mr. Morford said that in Cornwall slugs were considered as a cure 

 for hooping-cough, and Mr. Edwards noted that in some parts of 

 the country they were strongly recommended to those suffering 

 from consumption, Mr. Adkin referred to the impossibility of 

 satisfactorily preserving slugs for any length of time. Sooner or 

 later the body shrinks and the colour goes. A weak solution of 

 formalin, as a preservative, is only effective for a few months.

Annual Exhibition of Varieties. 



Mr. A. E. GiBBS, F.L.S., F.E.S., Vice-president, in the chair. 



Mr. A. E. Tonge exhibited : — 



(1) A specimen of Pyrameis atalanta with the band of the 

 hindwing orange in colour instead of red. It was taken at Deal. 



(2) A series of Poli/oiinnatiis icarus, males and females, selected 

 from the year's captures, to show extreme blueness in female 

 upperside and range of underside aberration in both sexes, taken at 

 Deal and Reigate. 



(8) A(jriades thetis {bellaiyns), females of very blue coloration of 

 the first brood from Reigate. 



(4) Selected specimens of A;/riades coridon, of both sexes, from 

 Deal, Ashford, and Reigate, showing considerable aberration. One 

 (J has a leaden-coloured upperside, with underside clouded and 

 indistinct, suggested as due to moisture.

 which the central and basal spots were united into an irregular 

 blotch.
