that he had met with a similar instance when rearing the 

 larvae of Lasiocainpa qziercifolia, L. Mr. West, of Streatham, 

 said the small larva was that of the hair worm [Gordius), 

 the ova of which had probably been swallowed by the lepidop- 

 terous larva when feeding. 



Mr. H. J. Turner exhibited eggs of the Dartford Warbler 

 {Melizophiliis undatiis, Boddaert.), from Godalming ; tlie 

 Wheatear (Saxicola cenanthe, L.), from Red Hill ; the Tree 

 Pipit {Anthns trivialis, L.), from Box Hill ; the Long-tailed 

 Tit {Acredula caudata, L.), and an Qgg which had not been 

 identified. He stated that the nest from which this egg 

 was taken was something similar to that of the Goldcrest 

 {Reguhis cristatiis, Koch). 



Mr. Turner further remarked that the Dartford Warbler 

 and Wheatear were becoming very scarce in Surrey. Mr. 

 Tugwell expressed an opinion that this was not the fact, and 

 thought it was owing to the shyness of the birds that they 

 were not noticed. Mr. Carrington said he had recently been 

 walking over Dartford Heath with Mr. Farn, who pointed out 

 several places where he had observed the nest of the Dartford 

 Warbler, and who added that it bred in the neighbourhood 

 each year, and with regard to the Wheatear, Mr. Carrington 

 was of opinion it was as abundant now as it had ever been. 

 The discussion was continued by Messrs. Tutt, Soutli, Step, 

 and Rice. 



Mr. F. G. Fenn read a paper on " British Land and 

 Freshwater Shells."

J. T. Carrington, Esq., F.L.S., Vice-President, in the Chair. 



Mr. A. Robinson exhibited ringed forms of the larvae of 

 Trichiura cratcEgi, L., from Monkswood, and asked whether 

 this was a common variety. 



Mr, Tugwell said the larvae of this species were exceedingly 

 variable. 



Mr, West (Streatham) exhibited a species of Noctua, bred 

 from a larva taken in Switzerland, at an elevation of 5000 

 feet; he thought the specimen was a typical example of 

 Acronycta leporina, L. Mr. South and Mr. Tugwell concurred.
