![Species 1. Hornera farehamensis, n. sp. Sjn. Hornera ramosa, D’Orb., G. R. Vine, 1891, Proe. Yorks. Geol. & Polyt. Soc. xii. pp. 54-56. Diagnosis. Zoarium thick, dichotomously branching tufts; the branches do not anastomose. Zooecia open somewhat regularly on the anterior side; the orbicular apertures form straight lines around the branches. In the middle line there is often an irregular and crowded series. The apertures are flush. The interzooecial pores are of medium size, but not very abundant, numbering from twice to thrice as many as the zooecia. The posterior side of the zoarium is deeply perforate, the punctures occurring in simple series, occasionally branching. Distribution. London Clay, Fareham. Type. Brit. Mus. No. B 3831. Figures. PI. XXXII. figs. 7-9. Affinities. This species has been identified by Mr. Vine as //. ramosa, D’Orbigny [No. 2, pp, 937, 938, pi. 608. figs. 6-10, pi. 773. figs. 1-3] ; from that species it appears to me to differ by the following characters: (1) the sections of the branches are round and not sub triangular; (2) the central series of zocecial apertures are very irregularly distributed; (3) the species figured by D’Orbigny has the exceptional character of a series of tubular prominences probably zocecial (see pi. 773. fig. 2); (4) the zoarium is irregularly branched and does not form the cupuliform structure shown by D’Orbigny (pi. 608. fig. 6). The nearest ally of this species appears to me to be Hornera concatenata, Reuss (No. ii, pp. 71, 72, pi. xxxv. figs. 5, 6), but in that species the pores on the back are few and far between, the number of zocecia in a transverse series is less, the pores on the front wall are much less numerous, and there is no irregular middle series. Genus Entalophora, Lamouroux, 1821. [Lamouroux, No. 2, p. 81.] Diagnosis. Pergens, No. 3, p. 357. Species 1. Entalophora tergemina x, n. sp. Syn. Idmonea gracillima ?, Reuss, Vine, 1889, Proc. Yorks. Geol. & Polyt. Soc. vol. xi. pp. 165, 166, pi. v. fig. 13. Diagnosis. Zoarium thick, apparently short. In section it appears quadrangular, with the angles well rounded. Surface minutely pitted. Zooecia crowded, long, expanding above; series of three or four open together along a straight line; there are four such triplets at not quite the same level in a series around the zoarium. There are 12 or 13 in a complete series. The zooecia are some- what infundibuliform, and have a somewhat quadrangular aperture. 1 Tergeminus, triple, referring to the apertures being usually in triplets.](https://iiif.wellcomecollection.org/image/b28141386_0108.jp2/full/800%2C/0/default.jpg)
