In one specimen the Eye is preserved, and is very large in propor- 
tion to the body. These Mollusks form the prey of the Physali, 
and were caught entangled in their Tentacula.

* Among the microscopic fossil shells placed hy D’Orhigny in the 
same Order as Nummulites {Foraminifires), Count Munster enu- 
merates 40 species from the Cretaceous free stone of Maestricht. 
Mr. Lonsdale also has discovered 16 species of microscopic forami- 
nifers in the English Chalk. (See V. I. p. 448, Note.) Microscopic 
shells of this Order occur in countless myriads throughout the Ter- 
tiary strata. (See V. I. p. 385.) 
Tile Sand of the Shores of the Adriatic, and of many Islands in tlie 
Archipelago, is crowded with recent microscopic shells of the same 
kind. 
It is mentioned in our Note, V. I. p. 382, that doubts have arisen 
as to the supposed origin of many of these minute multilocular shells 
from Cephalopods. Some recent observations of M. Dujardin have 
induced him to refer the Animals which construct the Miliola and 
some other microscopic foraminiferous shells, to a new Class of 
animals of lower degree than the Kadiata, and possessing a loco- 
motive power by means of minute tentacular filaments. He proposes 
to give them the name of Rhizopodes. Ann. des Sci. Nat. Mai, 1835- 
p. 312.
