On Specimens of Eozoon Canadense. 213 
so that they are in their essential characters minute acervu- 
line specimens of that species, and similar to those I describ- 
ed in my paper of 1867 as occurring in the limestones of 
Long Lake and Wentworth, and also in the Loganite filling 
the chambers of specimens of EKozoon from Burgess. Some 
of them are connected with each other by necks or processes, 
in the manner of the groups of chamberlets described by 
Giimbel as occurring in a limestone from Finland, examined 
by him. That they are organic I cannot doubt, and also 
that they have been distributed by currents over the surface 
of the layers along with fragments of Eozoon. Whether

they are connected with that fossil or are specifically distinct, 
may admit of more doubt. They may be merely minute 
portions detached from the acervuline surface of Kozoon, 
and possibly of the nature of reproductive buds. On the 
other hand they may be distinct organisms growing in the 
manner of Globigerina, As this is at present uncertain, and 
as it is convenient to have some name for them, I have pro- 
posed to term them Archosphierine, understanding by that 
name minute Foraminiferal organisms, having the form and 
mode of aggregation of Globigerina, but with the proper 
wall of Hozoon.
