LAGENIDAE 155 



358. Lagena lagenoides var. radiata (Seguenza) (F 227). 

 Five stations: 384-6; WS 204, 403. 



Very rare, but some very fine specimens were found at these deep-water stations. The 

 wing is flat, not sigmoid as in Silvestri's figure. The surface of the flask is generally 

 rough or stippled, sometimes faintly striate; but the markings are not strong enough to 

 compare them with L. sublogenoides var. striatula, Cushman (C. 1910, etc., FNP, 1913, 

 p. 40, pi. xvi, fig. 5), although the specimens at St. 386 approach that variety. 



359. Lagena lagenoides var. tenuistriata, Brady (F 228) (SG 226). 

 Three stations: 383, 385 ; WS 403. 



A single excellent specimen at St. 383 ; more frequent at the other stations. 



360. Lagena laureata, Heron- Allen and Earland (F 244). 

 One station: WS 505. 



A single very weak specimen. The species is abundant in the Falklands area but did 

 not occur in South Georgia. 



361. Lagena lineata (Williamson) (F 183) (SG 227). 

 Four stations: 170, 177, 363 ; WS 468. 



Extremely rare, usually only a single specimen at each station. The depths range be- 

 tween 329 and 4344 m. At the greatest depth, St. WS 468, the single specimen is quite 

 typical though rather coarsely marked. The others are of a more globular form, such as 

 were recorded from South Georgia, and the markings range between fine and coarse 

 striae. 



362. Lagena lucida (Williamson) (F 214) (SG 228). 

 One station: 170. 



Curiously enough this ubiquitous species occurs only at St. 170, where it is not un- 

 common and the specimens are large and typical. 



363. Lagena malcomsonii, J. Wright (F 217). 

 One station: 187. 



A single specimen only from the Palmer Archipelago, in 200 m. 



364. Lagena marginata (Walker and Boys) (F 221) (SG 232). 



Twenty-two stations: 170, 175, 177, 181, 187, 190, 194, 195, 200, 363, 384-7; WS 204, 403, 468, 

 481, 482, 483, 485, 505. 



Frequent and variable at Sts. 385, WS 482 and 483, more or less rare at the other 

 stations. The majority of specimens have a carina of narrow or medium width, but 

 specimens with broad carinae were found at some of the deeper stations, notably Sts 

 384, 385, 386 and WS 403. Fragments of what must have been enormous individuals 

 were found at Sts. 384 and 385. 



365. Lagena marginata var. cushmani, Wiesner (Plate VII, fig. 2). 

 Lagena marginata var. Cushman, 1910, etc., FNP, 1913, p. 38, pi. xxi, fig. 2. 

 Lagena cushmani, Wiesner, 1931, FDSE, p. 121, pi. xix, fig. 225. 



Two stations: 170, 385.
