LAGENINAE 379 



232. Lagena fimbriata, Brady (Plate XI, figs. 13 16). 



Lagena fimbriata, Brady, 1879, etc., RRC, 1881, p. 61 ; 1884, FC, p. 486, pi. Ix, figs. 26-8. 

 Lagena fimbriata, Sidebottom, 1912, etc., LSP, 1912, p. 422. pi. xx, figs. 24-6. 



Eleven stations: 51, 236; WS 80, 83, 88, 92, 93, 97, 248, 408, 433. 



The Falkland specimens are quite good and typical, the best at WS 88, 93 and 97. 

 Trigonal specimens at WS 83 and 93 (Plate XI, fig. 16). At 236, the specimens have 

 abnormally developed fimbriate bases. There is a constant tendency to pass into L. auri- 

 ciilata by the filling in of the basal excavation at its central point so as to form two 

 separate loops. At WS 433 a specimen showing the fine spinous processes figured by 

 Brady, pi. Ix, fig. 26 and referred to by Sidebottom {lit supra). 



Size varies greatly, ranging up to 0-35 mm. or more in length, 0-25 mm. in breadth. 



233. Lagena fimbriata var. occlusa, Sidebottom (Plate XI, figs. 17, 18). 



Lagena fimbriata, Brady, var.n. occlusa, Sidebottom, 1912, LSP, p. 423, pi. xx, figs. 27, 28. 

 One station: WS 89. 



Two specimens of the broad variety (fig. 28 supra). 

 Length, 0-23 mm.; breadth, 0-20 mm.; thickness, 0-13 mm. 



234. Lagena danica, Madsen (Plate XI, figs. 19, 20). 



Lagena danica, Madsen, 1895, FDH, p. 196, pi. O, fig. 4. 

 Lagena danica. Goes, 1896, DOA, p. 53, pi. v, figs. 11, 12. 



Four stations: 48, 388; WS 88, 90. 



Single specimens at each, the best at WS 88. Although the basal wings are well 

 marked in side view, they do not project, with the result that the edge view shows even 

 less of a basal cleft than in Madsen's figure. The base of our specimen is flat, and 

 abruptly truncated as shown in our figure 20. 



235. Lagena rizzae (Seguenza). 



Fissurina rizzae, Seguenza, 1862, FMMM, p. 72, pi. ii, fig. 50. 



Lagena rizzae, Heron-Allen and Earland, 1913, CI, p. 89, pi. vii, fig. 9. 



Lagena quadrata var. rizzae, Cushman, 1910, etc. FNP, 1913, p. 35, pi. xix, fig. 4. 



Three stations: WS 83, 88, 90. 



A single specimen at each. This little species has probably been overlooked at some of 

 the other stations. 



236. Lagena bicarinata (Terquem). 



Fissurina bicarinata, Terquem, 1882, FEP, p. 31, pi. i (ix), fig. 24. 



Lagena bicarinata, Heron-Allen and Earland, 1916, FSC, p. 46, pi. vii, figs. 2, 3. 



Four stations : WS 77, 83, 90, 92. 



Typical specimens are extremely rare. The best at WS 83 and 90. There is a con- 

 siderable amount of variation, not only in the shape of the test, which varies from
