340. Lagena globosa (Montagu) (F 169) (SG 217). 



Nineteen stations: 163, 170, 175, 177, 180, 196, 363, 383-6; WS 204, 403, 468, 469, 481, 482, 

 507B, 517- 



Frequent at Sts. 384, 385, where, in addition to fragments of typical specimens of 

 enormous size, almost every variety occurred, including ento-ectosolenian specimens, 

 specimens with broad everted rims round the aperture and compressed specimens of the 

 fissurine type (= Fissurina globosa, Bornemann). This fissurine form represents the 

 species at several stations including Sts. 177, 363 and WS 507 b, but generally speaking 

 it has the same distribution as the type. At most of the stations the species grows to 

 large dimensions, particularly noteworthy at Sts. 163, 170, 384, 385, 386, and WS 482. 

 These very large specimens usually have a simple basal aperture, in addition to the 

 normal radiate aperture of the type. 



341. Lagena globosa var. emaciata, Reuss. 



Lagena emaciata, Reuss, 1862 (1863), FFL, p. 319, pi. i, fig. 9. 



Lagena globosa var. emaciata, Sidebottom, 1912, etc., LSP, 1912, p. 381, pi. xiv, figs. 13-15; 

 1913, p. 165. 

 Three stations: 385; WS 506, 507 A. 



The only records which have been preserved are single specimens from these 

 stations. The variety probably occurs at many others but has been overlooked or 

 associated with L. apiciilata. 



342. Lagena globosa var. setosa, var.n. (Plate VI, fig. 52). 



Lagena longispina, Brady, 1879, etc., RRC, 1881, p. 61. 



Lagena longispina, Brady, 1884, FC, p. 454, pi. Ivi, figs. 33-5 (not 36 or pi. lix, figs. 13-14). 



Lagena longispina, Sidebottom, 1912, etc., LSP, 1913, p. 165, pi. xv, figs. 5, 6. 



Four stations: 386; WS 400, 403, 469. 



A single specimen at each of these deep-water stations in the Drake Strait, depths 

 3959-4773 m. They are merely a variety of L. globosa in which the base is covered with 

 short solid spines or hairs. 



Brady says that his species L. longispina is "only a variety of L. globosa, the shell of 

 which is armed at the base with a number of spines, either irregularly placed or, in 

 the compressed forms, springing from near the median line. Sometimes the spines 

 attain large dimensions, and specimens have been found in which they measure nearly 

 twice the length of the body of the test". 



His figures appear to represent two very distinct forms. The Figs. 33-5 on pi. Ivi are, 

 as he states, only a variety of L. globosa and identical with Sidebottom's specimens and 

 my own. The figures on pi. lix, however, and probably pi. Ivi, fig. 36, represent a form 

 bearing long extensions, which I cannot regard as homologous with the short spines 

 borne by the other specimens. I suggest that Brady's name be confined to the long- 

 spined form. 



343. Lagena globosa var. tenuissimestriata, Schubert (Plate VII, figs. 50, 51). 

 Lagena globosa var. tenuissimestriata, Schubert, 191 1, FFB, p. 67. 



Two stations: 175, 180. 



A single specimen at each station, depths 200-160 m.
