and Scotia Sea, ranging between 3328 and 4773 m., but is frequent at St. 385, rare or 

 very rare elsewhere. Two of the stations, 386 and WS 468, are outside the convergence. 

 Brady figures only a single specimen, in which the facial costae are confined to the 

 regions of the neck and base, the central area being clear. But in his description he says 

 that " the surface of the test is more or less costate or striate, especially near the base and 

 apex". My material shows a complete range from faintly striate at St. WS 468 to 

 strongly costate all over at St. WS 204. At Sts. 385 and WS 403 the full range of varia- 

 tion occurs. At the remaining stations the range is from faintly costate to the type as 

 figured by Brady.

One station: 385. 



A single very large specimen from just inside the Antarctic convergence line. The 

 surface granulation is much finer than is usually the case, otherwise it is quite typical. 

 This is normally a warm water species of the Indo-Pacific region. 



308. Lagena apiculata (Reuss) (F 174) (SG 200) (Plate VI, fig. 36). 



Fifteen stations: 170, 175, 200, 385, 386; WS 204, 205, 382, 403, 468, 469, 472, 481, 482, 489. 



Frequent and varied at St. 170, rare or very rare elsewhere. Practically all the varia- 

 tions referred to in the South Georgia report (SG 200) were observed. The large variety 

 referred to in that report was recorded at Sts. 170, 175, 200, WS 382, 469 and 482, and 

 at several of these stations was the sole representative of the species. At St. WS 468, in 

 addition to typical specimens, two were found which have been assigned to this species 

 with some doubt. They are cylindrical, rounded at both extremities and furnished with 

 a prominent entosolenian tube, not attached to the side of the test. They might equally 

 well be regarded as abnormally elongated L. ovum, or straight L. botelliformis . 



309. Lagena aspera, Reuss (F 182) (Plate VI, figs. 37, 38). 

 Three stations: 383-5. 



Very fine specimens were found at these three deep-water stations in the Drake 

 Strait, inside the Antarctic convergence line. They are of a massive type as regards the 

 construction of the test, which is globular and thick-walled, with a strong tapering neck 

 about equal in length to the diameter of the body. The surface markings by contrast are 

 weak, often strongest on the neck, while on the body they are mere rugosities, like the 

 skin of an orange. Cushman figures a similar but rather coarser form from the Pacific 

 (C. 1910, etc., FNP, 1913, p. 16, pi. xvi, fig. i). 



310. Lagena auriculata, Brady (F 245) (SG 201). 

 Six stations: 383-6; WS 204, 403. 



Extremely rare and confined to the deepest water stations. Although only eight 

 specimens in all were obtained, they represent four very diff'erent forms of this variable 

 species. At St. WS 204 it is a simple non-carinate flask very like a figure by Sidebottom
