Original Description

T. americana, parva, saepius microsc., celerius dilatata laevis, cellulis primis globosis (1/300 lineae l.), dein ovatis, summis in papillam superiorem externam productis subaculeatis.

Cellulae primae nonnullis spirales. Tales formae forsan proprio generi addicendae sunt: Heterohelix.

Translation (from Frerichs & Gaskill 1978)
T . americana, small, more often microscopic, rapidly expanding, smooth, first chamber globular (1/300 of a line), chambers ovate, final chambers produced into a spine.


Size:
initial chambers "1/300 line". according to wikipedia a Berlin foot was 314mm, an inch was 1/12 of a foot and a line 1/12 of an inch soothes would be 7µm - which is close to the modern measurement of 10 µm from Georgescu & Huber (2009) . [editor's comment - JRY 2019]
