have higher peristomes and are more fusiform and shorter. 

 These seem sufficient to separate them, apart from the differ- 

 ences in the zoaria, which in striata are irregular and flabelli- 

 form. The specimens occur on an Ostrea found in the Port- 

 land Oolite at Tisbury, and they are of interest as the only 

 Bryozoa known from this stage in England. The species is 

 well marked ; its nearest Cretaceous ally is B. Clementina, 

 d'Orb.*, which is, however, nearer to B. striata. B. port- 

 landica differs from B. Clementina in having a discoid 

 zoarium, the orifices more scattered, and longer zooecia.
