i64 DISCOVERY REPORTS 



401. Lagena stewartii, J. Wright (F 171) (SG 246). 



One station : WS 204. 



Only a single specimen was recorded from 3328 m.; it is probable that it occurs at 

 other stations but was not separated from L. globosa. 



402. Lagena striata (d'Orbigny) (F 188) (SG 247) (Plate VII, figs. 29, 30). 



Thirteen stations: 180, 191, 196, 383-6; WS 205, 403, 468, 469, 485, 506. 



Rare or very rare everywhere, most frequent at Sts. 385 and 386. With a single excep- 

 tion all the specimens are of the elongate form figured by Williamson; in some cases, 

 notably at Sts. 383 and WS 403, the specimens are very long with almost parallel sides. 

 The true d'Orbigny type with spherical test and long neck does not occur at all, but at 

 St. WS 469 a single specimen was found which is perhaps a modification of the type. 

 It is large, and has an almost globular body covered with very regular but faint striae. 

 The neck is short, very solid and covered with weak costae, formed by the extension of 

 some of the striae from the body of the test. It is altogether a very striking variety and 

 is figured. It comes from a great depth, 3959 m. 



403. Lagena striata var. strumosa, Reuss. 



Lagena strumosa, Reuss, 1858, FP, p. 434. 



Lagena strumosa, Reuss, 1862 (1863), FFL, p. 328, pi. iv, fig. 49. 



Lagena striata var. strumosa, Cushman, 1910, etc., FNP, 1913, p. 20, pi. vii, figs. 7-10. 



Three stations: 384, 386; WS 403. 



A single specimen of this apiculate variety was found at each station. 



404. Lagena striato-punctata, Parker and Jones, var. complexa Sidebottom. 



Lagena striato-punctata, var.n. complexa, ?>idf:hottom, i9i2,etc.,LSP, 19 12, p. 393, pi. xvi.fig. 11 ; 

 1913, p. 176. 



One station : WS 469. 



A single specimen from 3959 m. in the Drake Strait. It has a long delicate neck and 

 about twenty prominent costae bearing inconspicuous tubules. The intercostal grooves 

 are deep and granular in appearance. It is referred with some hesitation to Sidebottom's 

 variety, neither the figure nor the description being very distinct. 



405. Lagena sulcata (Walker and Jacob) (F 189) (SG 248). 

 Twelve stations: 170, 175, 200, 363, 383-6; WS 204, 205, 468, 507B. 



Usually rare or very rare, but frequent and variable at St. 385, though all the speci- 

 mens were small. Large and typical examples at Sts. 170, 175 and 200. A large 

 globular specimen with short thick neck and spinous base at St. WS 204, and a typical 

 specimen with very long neck at St. WS 507 B. The variety interrupta, Williamson, was 

 recorded at St. 363 and probably occurs at other stations, but was not regarded as 

 worthy of separation. At St. 384 the species was exceptionally variable; in addition to 

 the type, specimens running into L. gracilis and L. acuticosta were noted.
