Zoarium erect, bilaminar, and forming thick, short, subcylindrical shoots. Zocecia elongate, lanceolate, quincuncially arranged. The orifice is oval or suborbi- cular; it opens on the sloping upper surface of the high tumid head, which also bears a large peristomial pore. A pair of large avicularia occur immediately below the orifice. The zocecia are sharply defined by lines of depression marked by rows of areolae. The trypa is a median narrow slit. Gonoecia . Distribution. London Clay : Haverstock Hill (1 Bracklesham Beds, fide Vine). Type. Brit. Mus. No. 49661. Figure. PL XXX. fig. 11. Part of Mr. Vine’s type. Affinities. This species in its slit-like trypa closely resembles Adeonellopsis perforata (Reuss) [Eschara perforata, Reuss, No. n, p. 231, pi. xxxiii. fig. 5], but the latter has no peristomial pore. It differs from A. wetherelli, Greg., by the pair of avicularia forming a peristomial pore, instead of having one median avicularium; the trypa is also different. The specimen figured by Reuss [No. 7, pi. xi. fig. 6] as Eschara diplo stoma, Phil., also belongs to this genus, but differs in the form of the trypa and of the orifice. The two other forms (figs. 5 and 7) associated with it by Reuss seem different, and that represented in fig. 7 is probably a second species of Schismoporella. Suborder HOLOTHYRIATA. Family LEPRALIIDiE. Subfamily Lepealiinx Genus Lepralia, Hincks, 1880 (non Johnst. &c.). Diagnosis. Hincks, No. 2, p. 297. Species 1. Lepralia lonsdalei. Syn. Eschara brongniarti, pars, Lonsdale (non M.-Edw.), 1850, Dixon, Geol. Suss. pp. 161, 162, pi. i. fig. 9*. Diagnosis. Zoarium thick, encrusting. Zocecia small, ovate; very irregularly distributed. Form irregular, varying from somewhat elongate to short and round. Aperture lepralian, very large : lower margin straight or curved outwards; the lateral constriction is, however, very slight.
