Description. — Test froo, composod of sever?)! chambei's, early 

 portion close coiled in a single plane, later poitlon uncoiled and 

 made up of a more or less linear series of chambers; wall coarsely 

 arenaceous, usuall}^ rather thick; aperture single at the distal end 

 of the last-formed chamber in the adult uncoiled specimen, but in 

 the young usually at the base o'f the apertural face. 



This genus is distinguished from the t.ypical Ila/plopJiragmium of 

 Reuss by lacking the multiple apertures and lab^Tintliic chambers 

 of that genus. Both have the uncoiled later development. The 

 true HaplopJirac/mium is rather rare in the present oceans, but the 

 species have tlie character of multiple apertures. The name Ilaplo- 

 phragmium has been applied to coiled and uncoiled forms, trochoid 

 and irregularly formed specimens, but these are here divided struc- 

 turally into several genera.
