Comment.

Ehrenberg (1845b) introduced and used the name Surirella undulata . In this publication he described all species new to science formally with a Latin diagnosis. Because he did not mark the species as new to science, Ehrenberg introduced the name Surirella undulata as a new combination of Navicula undulata under the then accepted genus name Surirella . This combination can be verified by the drawing Ehrenberg (1854) provided e.g. for Berlin material "Brakisches, strichweis lebendes, Erdlager unter Berlin" ( Ehrenberg 1854: pl. 14: fig. 39). Since Ehrenberg published this taxon name already in 1838, his name has priority over Surirella elliptica .
