THE FORAMINIFERA OF THE RIVER DEE. 51 
the species :—The test is normally adherent, and, when young 
somewhat resembles that of Planorbulina mediterranensis. At 
a later stage it either spreads laterally over the surface of the 
body on which it is growing, or piles its little inflated chambers 
one upon the other in acervuline fashion, until the mass assumes 
a nearly hemispherical contour. It is tolerably common on the 
West coast of Ireland, and has been found by Mr. Bravy, 
Mr. Ropertson, and the Rey. A. M. Norman, in dredgings off 
the shores of Scotland and elsewhere. The loose specimens 
obtained from Hilbre and the lower parts of the Dee estuary, 
are generally somewhat rolled and abraded, as though they had 
been washed in by the tide, but I have also found it growing 
upon a Sertularian. 
All the species contained in this list have, with characteristic 
kindness, been carefully revised and authenticated by H. B. 
Brapy, Esq., F.RB.S. Those to which an asterisk is prefixed 
have been collected by Mrs. Enizapera Snone, whose persever- 
ing study has been rewarded by the discovery of several species 
new to the British seas. Some of the forms enumerated are 
only represented by one or two depauperated, broken, or 
unsatisfactory specimens, and it is very desirable that future 
observers should verify the occurrence of the shells marked 
“very rare.”
