Soc. vol. xi. p. 166, pi. v. fig. 15; id. ibid. vol. xii. p. 53. Diagnosis. Zoarium small, erect, rising from an encrusting, expanded base. The branches fork several times; they are triangular in section and well rounded behind; they end bluntly. Zocecia in short transverse series, alternately arranged. The zooecia are single at the base, but rapidly increase to rows of four; this decreases to three above. The inner- most zooecia are the longest. Peristome even, usually oblong with rounded angles; younger and isolated zooecia have oval or even circular apertures. Wall granular. Distribution. British: Bracklesham Beds, Bracklesham (Brit. Mus., Dixon and Vine Collections).—Foreign: Calcaire grossier, Parnes, Grignon, Chaumont, &c.; Laekenien; Uccle (near Brussels), de Foret, d’Assche. Figures. PI. XXXII. figs. 6 a, 6 b. Affinities and Differences. As this species belongs to the typical group of Idmonea it clearly differs from Idmonea (Tervia) seriatopora, Reuss, As there is no median line of zooecia it differs from Idmonea giebeli, Stol. From the third British Eocene species it may readily be distinguished, as in that the zooecia are always in alternate pairs. Genus Hornera, Lamouroux, 1821. [Lamouroux, No. 2, p. 41.] Diagnosis. Pergens, 1889, No. 3, p. 353. Type species. Hornera frondiculata (Lamarck), 1816, No. 1, pp. 182, 183. VOL. XIII.—PART VI.
