ditions, presents gradations of colour from the light to the dark shade, and 

 these have been named accordingly as separate sorts by various authors. 

 Something of a similar kind has already been proved to occur in Orchesella 

 cincta, Linn. References, descriptions, and synonyms are given of several 

 species, both new and of those already known, to which are added figures 

 of the insects themselves and their structural peculiarities. 



The nineteenth contribution to the molluscan fauna of the 'Challenger' 

 Expedition, by the Rev. R. Boog Watson, was read, in which descriptions 

 are given of a number of new species of Bidlidce. 



Anniversary Meeting, May 24, 1883.— Sir John Lubbock, Bart., 

 M.P., F.R.S., President, in the chair. 



Mr. R. M'Lachlan, for the Audit Committee, read the statement of 

 receipts and payments for the year. The Treasurer (Mr. Frauk Crisp) 

 followed with a detailed explanation of the various items; £750 had been 

 invested, making a total of about £5000, and a balance at bankers (30th

The Secretary (Mr. B. D. Jackson) read his annual report. Since the 

 last anniversary eleven Fellows and one Foreign Member had died and

 the sculptor's son, Mr. H. Power, of Florence. An engraving from Gains-

 by Mr. Howard Saunders, in the name of Mrs. Alston, as a bequest from 

 her son, the Society's late Secretary, Mr. E. R. Alston. 



The President then delivered his anniversary address, commenting

 collections in the new Natural History Museum at South Kensington. 



This was followed by reports on the various botanical and zoological 

 publications issued at home and abroad during the last twelve months.
