330. Lagena exsculpta, Brady. 



Lagena exsculpta, Brady, 1879, etc., RRC, 1881, p. 61 ; 1884, FC, p. 467, pi. Iviii, fig. i ; pi. Ixi, 



%• 5- 



Lagena exsculpta, Cushman, 1910, etc., FNP, 1913, p. 28, pi. xiii, fig. 5. 



Two stations: 384, 386. 



Two typical specimens of the globular type at St. 386, and several of the compressed 

 form at St. 384. In some of the compressed specimens the costae between the " furrows " 

 or grooves are very strongly developed beyond the base. 



Brady [ut supra) gives as a synonym of his species Lagenulina sulcata, Terquem 

 (T. 1875, etc., APD, part 2, 1876, p. 68, pi. vii, fig. 9). But Terquem describes his 

 specimen as "veliit costata", and the shading of the excellent figure indicates plainly 

 that the markings are solid raised costae -extending over the basal half of the shell, and 

 not grooves excavated in the shell, as in Lagena exsculpta. 



331. Lagena fasciata (Egger) var faba, Balkwill and Millett (F 213) (SG 211). 

 One station : WS 482. 



A single rather weak specimen. 



332. Lagena felsinea, Fornasini (SG 212). 



Twelve stations: 363, 373, 383-6; WS 204, 383, 468, 485, 506, 507B. 



Very rare, generally represented by one or two typical specimens, except at St. 

 WS 468, where it is not uncommon. The species appears to be quite cosmopolitan, 

 though in our material it is almost confined to deep water. 



333. Lagena fimbriata, Brady (F 232) (SG 213) (Plate VI, figs. 46, 47). 

 Eight stations: 201, 366, 383-6; WS 403, 507B. 



One or two small and weak specimens at Sts. 201, 366 and WS 507 b. More frequent 

 but never common at the remaining stations where it attains typical development, and 

 at which many of the specimens have a dense fringe of very delicate spines filling the 

 spaces between the basal carinae, and sometimes extending considerably beyond them. 

 The best examples of this were found at Sts. 384 and WS 403. 



334. Lagena fimbriata var. occlusa, Sidebottom (F 233). 

 One station : 385. 



A few typical specimens. 



335. Lagena formosa, Schwager (SG 214). 

 Five stations: 384-6; WS 403, 469. 



Confined to the very deep-water stations in the Drake Strait and Scotia Sea, two of 

 the stations being outside the Antarctic convergence line. It is rare everywhere except 

 at St. 385, where it is not uncommon. Most of the specimens are very large and typical, 

 except at St. WS 469, where the single example was small but with a very long neck. 

 At Sts. 384 and 386 enormous but fragmentary specimens were obtained, the largest 

 must have measured over 1-5 mm. in length when perfect. At St. WS 403 the species 

 was represented by two large specimens with very feeble striations on the face, not 

 sufficiently strong to entitle them to separation under Brady's varietal name comata.
