Esq., John Tristram Tristram-Valentine, Esq., James Herbert 

 Veitch, Esq., James John Walker, Esq., and John Watson, Esq., 

 were elected Fellows. 



Ml*. Alfred W. Bennett communicated some observations on 

 some new and little-known British freshwater Alg?e, Schizothrix 

 anglica and Sphceroplea anmilina. It was pointed out that Schi- 

 zothrix of Harvey's ' Phycologia Britaunica ' is really an Inactis. 



Mr. E. M. Holmes exhibited as a new British Marine Alga a 

 specimen of Gmcillaria divergens, a rare native of the warmer 

 portions of the Atlantic and the Mediterranean, which had been 

 recently found at Brighton by Mr. John Myles. The specimen 

 exhibited possessed tetrasporic and cystocarpic fruits not described 

 by Agardh. 



Mr. Pascoe exhibited a number of Crustacea and certain shells 

 of the genus Phorus, having various foreign substances attached 

 to them. 



Mr. Thos. Christy exhibited, and made remarks on, some 

 " liquid amber," or resin, Altingia excelsa, from Cochin China. 



The following papers were read : — 



1. " Life-History of a Stipitate Freshwater Alga." By George 

 Massee. (Communicated by the Secretary.) 



2. " On the Anatomy of Pallas's Sand-Grouse." By George 

 Sim, A.L.S.

John Gilbeet Baker, F.E.S., Vice-President, in the Chair.

Charles Curtis, Esq., and Percy Groom, Esq., were elected 

 Fellows. 



Prof P. M. Duncan made some supplementary remarks on a 

 specimen of Syalonema Sicholdii, which he had exhibited at a 

 previous Meeting. 



Mr. W. Hatchett Jackson exhibited, and gave an account of, 

 an Electric Centipede (G'co/ji/i/Z^/s electricus), detailing the circum- 

 stances under which he had found it at Oxford and the result of 

 experiments which he had made with a view of determiuino- the 

 nature and properties of the luminous fluid secreted by it. This 

 he found could be separated from the insect, and could be com- 

 municated by it to every portion of the integument. It was 

 pointed out by Mr. J. E. Harting that these observations had 

 been anticipated by Mr. Macartney in an elaborate paper on Lu- 

 minous Insects, published in the ' JPhilosophical Transactions ' for 

 1810 (vol. 100. p. 277).
