wings whit^ Several ab. obsoleta of both sexes, etc. In the latter

Mr. L. F. Hammond exhibited an aberration of Ancia medon, 

 captured in Abbotts Wood, with white coloration of entire insect 

 replaced by dull smoky grey or lead colour, this applying even to 

 the thoracic hairs and underside of abdomen, legs and palpi. 



He also showed a fresh specimen of Epinephele jurtina of a pale 

 silvery grey, with just a tint of brown in the sheen all over same. 



Mr. Hugh Findon exhibited a large collection of Australasian 

 Mollusca and contributed the following notes :— 



" The general interest of the exhibit lay in the fact that the New 

 Zealand shells, which formed the greater part of it, were collected 

 some 70 years or so ago, by a settler, when little notice was taken 

 of nature there. Scientifically, it was of interest as corroborating 

 the hypothesis that Australasia is still in Tertiary times, the shells 

 bearing much resemblance to our own tertiary and earlier fossil 



forms. 



" The Triijonia, from Tasmania, are the living representatives of 

 a genus which has become extinct elsewhere at the end of the 

 secondary formations. 



" The ' horny-shelled " snails, Paryiihanta, are not Helix, but 

 have their nearest European allies in Testacella, the slug with a 

 shell on its tail. 



" The sea-mussel, Mytilits, is almost indistinguishable from our 

 own common mussel, but the river mussels are a very early type 

 and more closely resemble American species." 



Mr. C. H. Williams exhibited the season's results of his breeding 

 Abraxas (jrofi>iitlaylata varieties, and his captures of aberrations of 

 Agriaden coridon. 



Mr. G. H. Cornish, on behalf of Mr. W. Juby, exhibited an

 thetis : (1) <? with R. hindwing violet, (2) g ab. obsoleta, (3) 5 

 exceptionally blue, (4) ? ab. striata. 



Ayriades coridon : (1) g ab. obsoleta, (2) ab. striata on R. fore- 

 wing, (3) ? s ab. obsoleta, (4) ? L. forewing with a pale patch, (5) 

 a form between ab. synyrajdia and ab. semisynyrapha. 



Ruiiiicia fhlaeas : (1) ab. schmidti, (2) $ asymmetrical hindwing
