" Only one of the pupae in my possession produced a butter- 

 fly, a rather undersized helice with the spots of the marginal 

 band reduced to a minimum. Mr. Battley bred four, one 

 male and one female typical, and two helice, and Mr, Harri- 

 son bred two males and two females, the latter var. helice. 

 About a dozen more were either crippled or made no attempt 

 to emerge. 



" A specimen of the variet}' /;^//a' was taken at Dawlish by 

 Mr. H. J. Turner and generously presented to me. It 

 deposited ova August 24th to 30th, which began to hatch on 

 August 31st, all being fertile. The lar\'ae (80) proved to be 

 very vigorous ; moulted first September 6th, and last 

 September 21st. They began to spin September 28th, and 

 pupated September 30th ; man}- died without spinning. 

 The pupas with two exceptions situated as in the previous 

 case. Fifty-two imagines (thirty males and twenty-two 

 females) emerged from October 30th to November 29th, of 

 \vhich eight (four males and four females) were crippled. 

 Seven females (two crippled) were referrable to var. helice, 

 one intermediate (lemon colour) and the rest, though paler 

 than usual, might be said to be typical. 



"A typical female, also taken at Dawlish by Mr. Turner, 

 deposited ova August 24th to 30th, about sixty per cent, of 

 which proved to be infertile. The larvae (seventy-seven) fed 

 up slowly and straggled on till mid-December. Over fifty 

 per cent, of the larvae pupated, but numbers of the pupas died. 

 Twenty-four (thirteen males and eleven females) imagines 

 emerged from November loth to December ist, of which 

 eleven (eight males and three females) were crippled." 



Mr. Lucas exhibited specimens of the land-shell Claiisilia 

 laminata, including examples of var. albinos from Streatley, 

 near Reading. 



Mr. F. Noad Clark exhibited, with the aid of the lantern, 

 a large number of Photo-micrographs of lepidopterous 

 ova. The result showed great skill and care, and the most 

 useful point was that the whole of the photographs were 

 done to one scale. He also read a number of most interest- 

 ing notes on the exhibit (see page 46).
