The Foraminifera of the Riber Bee. 
BY ita. Se PDA Br: 
HE results proposed to be offered in the following Catalogue 
have been attained from the examination of the Microzoa 
of the Estuary of the river Dee. Material for the purpose has 
been collected from all parts of the river from Chester to the 
Sea, principally by scraping the sand near low-water mark, but 
also by means of the tow-net and dredge. The richest and most 
productive gatherings of Foraminifera have been made at the 
following points, viz.:—Chester, from the sandbank opposite 
the old cheese-stage ; Saltney, from the sandbanks opposite the 
wharf, and also immediately below the next bend of the river; 
Holywell, from the pools on the shore near high-water mark ; 
and Hilbre Island, from among the rocks between the Little 
Eye and Middle Island. Sand collected at intermediate places 
either by scraping or dredging, was not nearly so rich as 
any of these four, either in point of the number of shells in it, 
or in the variety of species. Living specimens have been obtained 
from Burton Marsh, Holywell, and Hilbre Island. These may 
always be got by carefully scraping the surface of the velvety 
brownish mud at the bottom of the pools left by the tide, or 
by skimming the top of the water if this mud be found to have 
risen, as it sometimes will, under the influence of light, &e. 
This oozy mud should then be washed through a fine muslin 
net, to get rid of the impalpable part of it, and the residuum 
collected into small bottles, which should be kept uncorked in 
a cool place out of direct sunlight, when the Foraminifera will 
creep up the sides of the bottles, and will live there for many
