Messrs, E. Herox-Ai-lex, F.R.S., F.L.S., and A. Earlaxd, 

 F.li.M.S., presented a paper entitled "The Foraminit'era ot" Lord 

 Howe Island, South Pacific." 



Mr. A. E.VRLAND contributed a few supplementary remarks on 

 the allinities of the new genera described in the |)aper and on the 

 problems sugi;ested by tlie occurrence of so many novel forms in 

 a single locality. l)r. CahnaTi commented on the exceptional 

 beauty of the lantern-slides; Mr. Heron-Allen briefly replied. 



Mr. T. A. Dtmes spoke upon the " Seeds of tlie Marsh Orchids," 

 with lantern shdes, coloured drawings by Mrs. Godfery, and living 

 ])lants. He stated that the Marsh Orchids are classified in two 

 main groups: (1) " Maculata? " ; (l?) " Latit'oliaj." 



The chief forms are: — Maculatne: (a) macnlatn T,. = FncJisii 

 Druce ; {h) ericetonnn Lint.=^)r(/'coa' Webst. ; (c) O'Jvelli/i Dnice ; 

 and Latifoliaj: (a) j^nHernussa Druce; (b) incarnata L. ; (c) j)Hr- 

 inireUa Stepli. p. & f. 



As all of these are described by characters taken from parts 

 other than the seeds, it seemed advisable to examine tlieir ripe 

 seeds also. 



The two main groups are easily separable by a single feature of 

 the testal cells: — Maculatre : testal cells sculptured {i.e., with 

 internal coils of thickening) ; LatifoliiE: testal cells not sculptured. 



Other distinctions he in the form of the testal cells and the 

 breadth and thickness of their common walls. 



Similarlv the forms within each group are readily distinguishable 

 bv their seeds: — Maculata; : (a) macnlatit Ij. = Fachsii. Druce, apex 

 of testa curved and pointed, coils loose; (b) ericctorum Lint.= 

 pneco.v Webst., kernel about 30 per cent, laiger than in either of 

 the other two forms, coils loose, less developed than in (a); 

 (c) 0' KeUiji Druce, a long, almost straight, narrow seed, with the 

 coils close and pronounced. Ijatifolia): {a.) pratermissa Dvwce, s. 

 long straight seed, not nuich dilated above the kernel, which is 

 about the same breadth as the adjacent portion of the testa ; 

 (b) ■incarnata L., a much shorter and broader seed than (a), 

 greatly dilated above the kernel which is distinctly narrower than 

 the adjacent portion of the testa, the mesh of the testa smaller 

 tlian in (a) ; (c) jmrpnreUa Steph. p. & f., the smallest of the 

 three, testa ilusky, indented on one or both sides above the 

 kernel and tapering to a point, mesh small.
