Diagnosis. — Zoarium circular, forming very large disks, 

 often somewhat irregular. 



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

 long, punctulate. 



Peristomes slightly raised, arranged regularly along slightly 

 curved lines. 



Formula.— 1 2 d 1. 



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

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



12. Berenicea coartata, sp. n. 



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

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



Diagnosis. — Zoarium in somewhat thick irregular sheets. 



Zooecia very crowded and visible only at the ends. 



Peristomes well raised, quincuncial in arrangement, very 

 densely packed ; the distance of the orifices from one another 

 is only equal to their diameter. 



Formula— -2 1 * 2. 



Distribution. — Inferior Oolite, Cotteswolds ; Great Oolite, 

 Richmond 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 zooecia, 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 closely 

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



The species seems to me exceptionally well marked.
