Some doubt exists as to the nature of the organism figured 

 in PI. 13, Fig. 2, and it is desirable that an attempt should 

 be made to observe living specimens, which should not be difficult 

 to obtain, as they are of common occurrence. I had referred 

 my specimens to Cornuspira foliacea, Philippi, to which the 

 outspread test bears some resemblance. Mr. Joseph Wright, 

 however, on examining them, informed me that he was well 

 acquainted with the form, which he regarded as the tube of 

 an Annelid, and he added that this opinion had been confirmed 

 by the late Mr. H. B. Brady, to whom he had submitted 

 specimens. Mr. Wright kindly supplied me with a British 

 example of C. foliacea, Philippi, which certainly differs widely 

 from the Bognor specimens, being very depressed and outspread. 



I thereupon withdrew C. foliacea from my list ; but having 

 subsequently found the abnormal specimens figured in PI. 13, 

 Figs. 3, 4, which closely resemble examples of multiple plastogamy, 

 such as is frequently observed in the Foraminifera, I have 

 thought it advisable to draw attention to them in the hope that 

 some local observer may settle the nature of the organism.
