CORRIGENDUM.—SERIES IX. 
I have committed an error in referring the diatom I have called Awlaco- 
discus ? paradoxus to that genus. It is certainly an Omphalopelta. The 
large, distinct granules, resembling so closely those of various Aulacodisci, 
and the sort of line leading to the processes (not brought out by the 
engraver) led me at first to doubt its true position.
