202 ARTHUR EARLAXD ON THE FORAMINIFERA OF 



records from the south-west of Ireland, 38 — 110 fathoms, 

 but he informs me that his specimens were as spherical as 

 Orbulina universa, d'Orbigny. 



Although the Bognor specimens are so different in appearance 

 from Brady's figures and Mr. Wright's Irish specimens, they 

 agree fairly well with Brady's description of the species, which is 

 admittedly subject to great variation. It further appears that 

 fossil specimens are of greater diversity than recent ones. 

 Writing of Dr. Haeusler's Jurassic specimens, Brady states that 

 " comparatively few show any signs of external symmetry."
