While T. papillata is best known as a Recent form, it has been recorded 
by Chapman and Ilowchin from tlu' Permian of New South Wales and by 
Morernan from the Silurian .of U.S.A.

Test free, comparatively larg(a spherical, thick-walled, but variable in 
this respect, central cavity large, conneid-ed with tiui outside surface by 
numeious mod('ratt4y-sized pits which extend iiregulaiiy through the thickness 
of the shell wall and roach the exterior surface through minute o]ienings ; 
wall comjiostxl of line sandy material fairly w('ll cemtuited, with a thin compact 
surfaces layer. 
Dianu'ter of holotype, 2* 2 mm., other s])ecim(nis an* slightly larger. 
Holotype from Sample 7 (Ijltujula- beds). 
As far as I am aware, tlam^ is oidy one previous record, tliat of Moreman 
from the Silurian of U.S.A. , of this genus as a fossil. It is thorefor(^ specially 
intere^sting to moot with it in such numbi'rs in the l-*ermian of Australia. The 
specimens are oxipiisitely prescu’vixl and every detail of structure can Vie 
studied as readily as in the best Recent material. 
In the living condition, Crithionina is Ijost developed in cold waters, 
particularly in the North Atlantic, where it occurs in immense numbers.
