228. Lagena lagenoides var. tenuistriata, Brady. 



Lagena tubulifera var. tenuistriata, Brady, 1879, etc., RRC, 1881, p. 61. 



Lagena lagenoides var. tenuistriata, Brady, 1884, FC, p. 479, pi. Ix, figs. 11, 15, 16. 



Lagena lagenoides var. tenuistriata, Cushman, 1910, etc., FNP, 1913, p. 39, pi. xvi, fig. 3. 



Four stations: 230; WS 93, 217, 245. 



A single specimen at each station, all of them identical in form with British specimens 

 but somewhat larger. 



229. Lagena ornata (Williamson). 



Entosolenia marginata var. ornata, Williamson, 1858, RFGB, p. 11, pi. i, fig. 24. 

 Lagena ornata, Heron-Allen and Earland, 1913, CI, p. 88, pi. vii, fig. 8. 



Two stations: WS 88, 90. 



A single typical specimen of this very distinctive form at each station. Outside 

 British seas, where it is abundant, the records are few and far apart. 



230. Lagena quadralata, Brady (Plate XI, figs. 9-12). 

 Lagena quadralata, Brady, 1884, FC, p. 464, pi. Ixi, fig. 3. 



Four stations : 228, 235 ; WS 83, 93. 



Brady lays stress on the fact that his species has four wings only, but we have speci- 

 mens, not only from the Falklands but elsewhere, exhibiting a varying number of wings, 

 between four and eight, but otherwise agreeing with his figure and description. 



The number of wings appears therefore to be useless for the purposes of diagnosis. A 

 more reliable feature is the constant presence of the conspicuous tubules in the wing to 

 which he also refers. These appear to indicate an affinity with Lagena lagenoides. Will., 

 and we think it probable that Brady's species is merely a polygonal form of that species. 

 We therefore suggest as an amended description: "Test flask-shaped, with a produced 

 and sometimes elongate neck, from the base of which a varying number of conspicuously 

 tubulated wings originate, and vertically encircling the test, join at the base. The space 

 between the wings is filled with weak vertical striae". 



L. quadralata was found in some numbers at WS 83, single specimens only at the 

 other stations. 



Average length, 0-22 mm.; breadth, o-ii mm. 



231. Lagena marginato-perforata, Seguenza. 



Lagena marginato-perforata, Seguenza, 1879-80, FTR, p. 332, pi. xvii, fig. 34. 

 Lagena marginato-perforata, Heron-Allen and Earland, 1913, CI, p. 86, pi. vii, figs. 5, 6. 

 Lagena marginato-perforata, Heron-Allen and Earland, 1914, etc., FKA, 1915, p. 663, pi. 1, 

 figs- 24-30- 

 Five stations: WS 83, 88, 90, 92, 93. 



A single strongly marked specimen at each station.
