56 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



B, squamigera I have only a single example, of the identity 

 of which I am not at all assured. 



Virgulina schreibersii, Cygjek. 

 Very rare, but specimens typical. 



Bolivina spp., d'Orb. 



B, cenariensiSf Costa, was erroneously described in the 

 Foraminifera of the Eiver Dee, as J5. costata, d'Orb. 



Cassidulina spp., d'Orb. 



C, kevigata and (7. crassa are both of rare occurrence and 

 feeble development in the district. 



Lagena spp., Walker and Jacob. 



The beautiful genus Lagena is represented by a great 

 variety of forms, every one of which has been found to extend 

 even into the brackish water of the River Dee. L. sulcata 

 and L. Icevis are universal and are common everywhere 

 round the coast. The species L. semistriata, L, striata, L. 

 marginata, L. squamosa, L. lucida, and L. apiculata are 

 also general, but much less common. The remaining 

 species have not yet been observed in our district beyond 

 the estuary of the Dee. Previous to its occurrence in the 

 Dee L. aspera had only been known as a Tertiary fossil 

 form. L. gracilis, L. orhignyana, L. ornata, L, pulchella, 

 and L. hispida are also exceedingly rare. The twenty-nine 

 species named in this list do not include all those known 

 as British, and it is very probable that further observations 

 will considerably extend the list. 



Nodosaria spp., Lamk. 



Of this genus all the six species observed are of general 

 distribution, excepting only N. hispida, of which I have seen 

 only one specimen, and that a broken one, from the river 

 Dee, near Hilbre Island. Uncertainty as to its name caused 

 me to omit it from the List of Dee Foraminifera, but Messrs.
