![and in other features. From the common and widely distributed C. 7'acliata [Moll, No. i, p. 63, pi. iv. fig. 17] this species differs by its larger orifice and by the furrows being more numerous and differently arranged. Among recent species it most closely resembles C. philomela, Busk [No. 8, pp. 132-3, pi. xvii. fig. 6, pi. xxii. fig. 7], to which it is allied by the large size of the orifice and the big globose ocecia; it differs, however, in the ooecia being plain in the recent species, and also in having more pores on the furrows and none in the middle line. Probably the nearest ally to this species is Cribrilina manzonii \Lepralia manzonii, Reuss, No. 14, p. 171, pi. i. fig. 6], from Modling, nearVienna, which agrees with it in the large size of the orifice and the arrangement of the furrows: Reuss does not figure any ocecia, and consequently this important character cannot be used for comparison ; but the absence of the pair of large lateral avicularia and the greater number both of pores and furrows in C. manzonii are sufficient to distinguish the two. The species belongs to Cribrilina, even restricted as narrowly as is done by Dr. Jullien [No. 3, 604]. Family MICROPORHXE. Genus Micropora. Diagnosis. Hincks, No. 8, pt. i. p. 161. Species 1. Micropora cribriformis, n. sp. Syn. Membranipora holostoma, Busk, var. perforata, G. R. Vine, 1891, Proc, Yorks. Geol. & Polyt. Soc. vol. xii. p. 60. Diagnosis. Zoarium encrusting. Zooecia oval, sometimes tapering below. The lower part of the front wall is very tumid and rises above the raised margin. The aperture is small; the upper margin is regularly curved, the lower margin sinuous. The front wall is crowded with maculae, which are very irregular in form and numbers. There is usually a pair of narrow slit- like opesiulae situated at the extreme margin of the ocecia, just below the corners of the aperture. Distribution. Barton Beds, Barton. Type. Brit. Mus.

This species is very clearly marked by the sinuous lower border of the aperture and the cribriform aspect of the whole front wall. Both characters, as well as the form of the zooecia and other less important points, separate it from M. holostoma (Busk) [No. 6, p. 36, pi. iii. fig. 11], from the Crag. Probably the most nearly allied species is M. gracilis (Miinst.) [Cellepora gracilis, 2 m 2](https://iiif.wellcomecollection.org/image/b28141386_0085.jp2/full/800%2C/0/default.jpg)
