Diagnosis. — Zoarium circular, forming very large disks, 

 often somewhat irregular. 



Zocecia crowded, so visible only at distal ends ; cylindrical, 

 long, punctulate. 



Peristomes slightly raised, arranged regularly along slightly 

 curved lines. 



Formula.— I 2 d\. 



Distribution. — England: Bradford Clay, Wilts; Cornbrash, 

 Yorkshire. Bajocian — Coralliau : France, Germany, Austria. 



12. Berenicea coartata^ sp. n. 



Diastopora diluviana, pars. Vine, 1884, Poljz. Richmond Boring, 

 Quart. Journ. Geol, Soc. vol. xl. p. 787. 



Diagnosis. — Zoarium in somewhat thick irregular sheets. 



ZooBcia very crowded and visible only at the ends. 



Peristomes well raised, quincuiicial in arrangement, very 

 densely packed ; the distance of the orifices from one another 

 is only equal to their diameter. 



Formula. — 2 1 i 2. 



Distribution. — Inferior Oolite, Cotteswolds ; Great Oolite, 

 Hichmond Boring and Bath. 



Affinities. — This species is most closely allied to B. sco- 

 binula, Mich. From this it differs in the much greater 

 crowding of the raised portions of the zocecia, and from these 

 being regularly quincuncial in arrangement. In B. exilis, 

 Reuss [B. cricopora. Vine), the distal portions of the zooecia 

 rise from a flat crust. In B. coartata they are so cLjsely 

 packed that no flat basal expansion can be seen between them. 



The species seems to me exceptionally well marked.
