BIBLIOGRAPHY. 
The following synopsis contains the titles of few memoirs beyond those which are, in 
one way or other, made use of in the present monograph. There are, doubtless, other 
papers with casual notices of the occurrence of Polymorphine which have eluded our 
search; but we believe the list represents almost exhaustively what has been written on 
the genus. In some few instances we have made use of the references in Professor Wil- 
liamson's * Recent Foraminifera of Great Britain.” |
