Citation: Heterohelix Ehrenberg 1843
taxonomic rank: Genus
Type species: Textillaria americana Ehrenberg 1843
Described on page(s) : 429

Current identification/main database link: Heterohelix Ehrenberg 1843

Original Description

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

Approximate translation (by JRY 2019 - with assistance from google translate)
Sometimes the first chambers are spirally arranged. These forms can perhaps be assigned their own genus: Heterohelix.
N.B. This brief description appears after the description of Textilaria americana and is used to distinguish this form from similar biserial forams without the initial spiral portion. 

Editors' Notes
NB Gender - the greek word helix is a feminine noun.
The generic descriton follows the description of Textillaria americana and is generally taken as meaning that forms similar to T. americana, but with an initial spiral, should go in the new genus Heterohelix. See discussions in Loeblich 1951, Frerichs & Gaskill 1978, and Georgescu & Huber 2009.
