Zoarium encrusting. Zocecia with prominent raised margins, front 

 depressed, wholly calcareous. Orifices semicircular, or suborbicular, en- 

 closed by a calcareous border. Hincks, ' Brit. Mar. Polyz.,' p. 173.

1848. Genus Ceibrilina, Gray. (Reptescharella, d'Orbigny.) 



Zoarium encrusting. Zocecia contiguous, having the front more or 

 less occupied by transverse or radiating punctured furrows. Orifice semi- 

 circular or sub-orbicular. (Hincks, ' Brit. Mar. Polyz.,' p. 184.) 



108. Cribrilina fragilis, d'Orb. (Semiescharipora), 'Terr. Cret.,' pi. 717, 



fig. 9. 



The British examples are closely allied to the C. radiata, Moll. ; and 

 the Q^agilis, d'Orb., may be only one of the many synonyms of this 

 world-wide species. 



109. Cribrilina linearis, sp. n. 



In habit the nearest apparent ally of this species is the HippotJioida 

 brevis, Reuss, ' Der Bryoz. u. Foram. des unteren Planers,' pi. 24, fig. 7, but 

 Reuss' figure does not show any cribriline features, and d'Orbigny does 

 not give a figure of any linear examples of Cretaceous Beptescharella. 



110. Cribrilina nitidiformis, sp. n. 



This species is closely allied to the very variable Memhramporella 

 nitida, Johnst.
