Conoglobigerina helvetojurassica (Haeusler). Scale bars for all specimens represent 50 µm; scale bars for wall texture scans 1a and 3a are 20 µm long and for wall texture scan 2a is 10 µm long. 14 Conoglobigerina helvetojurassica (Haeusler). Sample 4 mid, Eisengraben Section, Birmenstorfer Schichten, Transversarius Zone, Oxfordian, Canton Aargau, Switzerland. The specimen in sem scan 1 is the proposed neotype, with typical specimens of the taxon in sem scans 2, 3 and 4 from the same sample. Aperture likely was arch shaped in sem scans 1, 2 and 3 and is clearly loop shaped in sem scan 4. SEM scans 1a, 2a and 3a show the reticulate wall texture of specimens 1, 2 and 3. 59 Conoglobigerina helvetojurassica (Haeusler), Tojeira Formation, Lower Kimmeridgian, Montejunto area, Portugal. Specimen 7 is from sample 24/2P; specimens 5, 6 and 9 are from sample T2/1 and specimen 8 is from sample T2/2. The Tojeira specimens have a reticulate wall (imperfectly so on some chambers in specimens 6 and 8) and arched to looped aperture with lip
