Distrihdtioii of ^accammina sphferica, etc. 2i 



-:i> 



Addendum. 



Since this paper was completed we have, through the kind 

 offices of J. O. Borley, Esq., M.A., been permitted by the Secretary 

 of the Board of Agriculture and Fisheries to examine a number of 

 the dredgings made in the Southern or English area of the North 

 Sea by the Fisheries cruiser ' Huxley ' (International North Sea 

 Investigations — England). The evidence obtained from the few 

 hauls a^ present examined, all of which have been selected from 

 the deeper and muddier areas, tends to confirm the observations 

 made in the deeper Northern areas. Both Psammosphdera and 

 Saccainmina have been recorded, but the specimens of Saccammina 

 are extremely small, in no case exceeding 0*65 mm. in diameter^ 

 and the smallest specimen seen was only 0'125 mm. in diameter.
