6 PEOCEEDINGS OF THE NATIONAL. MUSEUM vol.67 



Occurrence. — Lower Cretaceous (Valangian) : Sainte-Croix (Vaiid), 

 Switzerland. The authors have noted this species at Arzier (Vaud), 

 at Vassy (Haute Marne), Les Saints-en-Puisaye and Les Crotites 

 (Yonne), and Morteau (Doul s), France.

 British Museum, vol. 1, p. 108, pi. 7, fig. 4. 



Gregory, 1899, wrote: " The name of the species refers to the thick 

 form of the zoarium, but the most interesting feature of this bryozoan 

 is its tendency to grow in a series of zoarial groups, as if it were a 

 very primitive form of Cellulipora." 



There is no reason to separate this species from the group Celluli- 

 jjora, the exterior aspect being absolutely identical; the cellules are 

 very short and cylindrical. 



Occurrence. — Lower Cretaceous (Aptian) : Faringdon, England, 

 and Ervy, Switzerland. 



Plesiotype.— Cat. No. 69832, U.S.N.M.

Gregory, in 1899, identified this species with Prohoscina fasciculata 

 Reuss, 1845. This is possible, and we refer the reader to page 29 

 of his catalogue for the synonomy and geological distribution. How- 

 ever, it differs from Prohoscina zic-zac D'Orbigny, 1851. Our speci- 

 mens correspond to the figure given by D'Orbigny and we therefore 

 cite only this reference.
