THE FORAMINIFERA. 43 



and descriptions given in Mr. Brady's splendid monograph 

 on the Foraminifera collected during the cruise of H.M.S. 

 " Challenger." The thorough and comprehensive character 

 of this publication will render comparatively easy all future 

 work upon Foraminifera. From the knowledge gained 

 by the examination of such large series of examples, Mr. 

 Brady has re-classified and arranged the Foraminifera, 

 and has considerably modified their nomenclature. I have 

 not hesitated to adopt fully all these changes. This will 

 account, in part, for the differences between the list above 

 referred to and that appended below. The same fact must 

 also be borne in mind when comparing the lists of forms 

 occurring in Dublin Bay and not in Liverpool Bay, and vice 

 versa, some few of them being mere differences of name, 

 Messrs. Balkwill and Wright's list of " Recent Dublin Bay 

 Foraminifera,"* having been published just prior to the 

 " Challenger " volumes. 



Material for examination has been obtained chiefly by 

 scraping the sand or mud in the most promising-looking 

 places between high and low water marks. The most prolific 

 gatherings have been obtained at the following points : — 



A sandbank opposite the old Cheesestage at Chester. 



A sandbank opposite the wharf at Saltney. 



A sandbank opposite Connah's Quay. 



Tide pools on muddy shore at Holywell, 



Between the rocks at Hilbre Island. 



The shore, Isle of Man. 



Stony shore, laminarian zone, Llandulas Point. 



Muddy and stony shore, laminarian zone, Colwyn Bay, 

 near Little Ormes Head. 



Under the pier, Llandudno. 



The Conway shore of Great Ormes Head.
