LAGENIDAE 163 



FDSE, p. 120, pi. xviii, fig. 219). Both the description and figure appear to agree with 

 L. squamoso-sulcata. 



397. Lagena staphyllearia (Schwager) (F 224) (SG 245). 

 Six stations: 180, 384, 385 ; WS 205, 403, 506. 



Single specimens only except at St. 385, where two were recorded. The specific name 

 is very loosely used for any compressed form with spinous base, but Schwager's type is 

 fairly distinctive. It represents a somewhat compressed but non-carinate form, with 

 three rather prominent equally-spaced basal spines. The type occurs at St. 385 with 

 the typical three spines, at St. WS 403 with the middle spine almost suppressed, and at 

 St. WS 506 with the two outer spines only. At the remaining stations the specimens are 

 zoologically L. margmota with basal spines. The test is compressed, more or less 

 distinctly carinate, and the basal spines vary between three and five in number. 



398. Lagena stelligera, Brady.

Lagena stelligera, Cushman, 1910, etc., FNP, 1913, p. 26, pi. xii, fig. 3. 



Lagena stelligera, Sidebottom, 1912, etc., LSP, 1912, p. 391, pi. xv, figs. 28, 29; pi. xvi, 



figs. 1-4; 1913, p. 174- 

 Four stations: 383, 385, 386; WS 469. 



Very rare everywhere. All the stations are in deep water. This is a most variable 

 species, the range of form being well illustrated by Sidebottom. At St. 383 a single 

 specimen exactly like Brady's type figure ; at St. WS 469 a practically identical specimen 

 but without the basal costae; at St. 386 these two forms occur together; at St. 385 the 

 type is long and slender, very like Sidebottom's fig. 29 {lit supra). 



399. Lagena stelligera var. eccentrica, Sidebottom. 



Lagena stelligera var. eccentrica, Sidebottom, 1912, etc., LSP, 1912, p. 392, pi. xvi, figs. 5, 6; 



1913. P- 175. Pl- XV, fig. 30. 



Lagena stelligera var. excentrica, Heron-Allen and Earland, 1922, TN, p. 148. 



Three stations: 384, 385, 386. 



One specimen only at Sts. 384 and 385, and two at St. 386. 



In this variety the basal collar is replaced by a more or less inconspicuous ring of solid 

 shell substance encircling the base of the test. The shape of the ring according to Side- 

 bottom is variable, hence presumably the varietal name. In the Discovery specimens 

 the ring is always circular, generally prominent, notably at Sts. 385 and 386. At the 

 latter station two specimens were found, in one of which the base was prolonged into a 

 short blunt spine in the centre of the ring. 



400. Lagena stelligera var. nelsoni, Heron-Allen and Earland. 



Lagena stelligera var. nelsoni, Heron-Allen and Earland, 1922, TN, p. 148, pi. v, figs. 20-22. 



Two stations : 175 ; WS 482. 



Some very good and typical examples at St. WS 482. At St. 175 only a single ab- 

 normal specimen, which has not the usual beak, turned sideways and containing the 

 aperture. The aperture is at the side of the test where the beak should be.
