A paper by Dr, Ign^acio Boliyar aud Mr. Cuaeles Ferriere, 

 B.Sc, on the " Orthoptera-Phasinid^e of the Seychelles," and 

 communicated by Prof. J. Stanley GtARDiiner, P.R.S., F.L.S., 

 was read by the Zoological Secretar\% who, in illustration of this 

 paper, showed living examples of Phasinidie and their eggs, 



Mr. W. F. Kirby, Miss E. Pearse (who also showed specimens), 

 Miss E. M. AVaketield, Dr. A. P. Young, and Dr. Otto Stapf, 

 Sec.L.S., joined in the discussion which followed. 



Miss May Eathboxe exhibited a specimen of TrifoUam repens 

 which showed phyllody of the carpels in a very distinct manner, 

 the axes of many of the flowers being prolonged into a single 

 leaflet, subtended by stipules, the rest of the flower calling for no 

 remark. (Abstract, p. 79.) 



Miss E. M. Berridge, the President, Dr. O. Stapf, Dr. C. E. 

 Moss (visitor), Mr. H. E. Darlington, the Eev. E. .S. Marshall, 

 and Dr. R. E. Gates (visitor), contributed further observations. 



Mr. J. A. Ltddell's paper, " On Nitocrameira hdeUurce, a new 

 genus of parasitic Cantliocamptidse," communicated by Prof. G. C. 

 Bourne, F.E.S., F.L.S., was read in abstract by the Zoological 

 Secretary, and commented on by the Eev. T. E. E. Stebbing, 

 Dr. W. T. Caiman, Prof. Dendy, Sec.L.S., and the President. 



The Botanical Secretary gave an account of a paper by Mr. W. 

 "West and Prof. G. S. "West entitled " On the Periodicity of the 

 Phytoplankton of some British Lakes." 



Mr. H. jN". Dixon showed a series of plants from South Poi'tugal, 

 stating that the plants shown were collected on a botanical visit 

 to Algarve in company with Mr. W. E. Nicholson in May, 1911. 

 The trip was mainly taken with a view to bryophytic study, and 

 the phanerogams were only incidentally collected. They were 

 not shown with special reference to their botanical interest, 

 though some of them were decidedly rare, but chiefly in order 

 to draw attention to the method of mounting in some instances, 

 certain of the specimens being mounted on sheets of black 

 paper, instead of the ordinary white. In some cases, as for 

 instance with white and yellow flowers, or with many grasses, 

 the colour of the flower is shown up much better by the contrast ; 

 and in others, where this is not conspicuously the case, the black 

 background produces a restful ness to the eye which probably, 

 quite apart from colour contrast, is an advantage. It is not 

 suggested that in all cases, or for herbarium purposes, there is any 

 advantage gained, but for exhibition purposes, and for a certain 

 class of plants it seems an improvement over the ordinary white 

 sheet. The surface should of course have as little glaze as possible, 

 and a paper should be chosen which has been found to bear con- 

 sidei'able exposure to light without discoloration.
