Bull. U. S. Nat. Mus., No. 71, 
June 30, 1910, pp. i-xiv, 1-134, 
figs. 1-203. 
This is the first part of a work the intent 
of which is to describe and illustrate the 
Foraminifera of the North Pacific Ocean; 
it includes the families Astrorhizide and 
Lituolide, together often known as the 
arenaceous foraminifera, and commonly 
considered the more primitive group. 
A considerable number of changes in 
the nomenclature and systematic arrange- 
ment have been made in an attempt to 
separate more clearly species and groups 
which, after the study of the extensive 
material available, appear to be dis- 
tinctive. 
The collections upon which this mono- 
graph is based were brought together as a 
result of the work of the various vessels of 
the Navy Department, the Coast and 
Geodetic Survey, and the Bureau of Fish- 
eries.
