Lagena intermedia, Sidebottom {non Rzehak), 1912, etc., LSP, 1912, p. 399, pi. xvii, figs. 1-3; 



1913, p. 180. 



Lageiia intermedia, Cushman, 1910, etc., FNP, 1913, p. 29, pi. xiii, fig. 4. 



Three stations: 384, 385; WS 403. 



Very rare, but excellent specimens of this normally Pacific species were found in the 

 deep water of the Drake Strait and Scotia Sea. 



Sidebottom's specific name had been anticipated by Rzehak, who described and figured 

 a striate Lagena under the name L. striata var. intermedia (R. 1885, NMO, pp. 81 and 90, 

 pi. i, fig. 6). I have therefore associated the species with the name of my late friend 

 Henry Sidebottom, who did so much valuable work on the Lagenae of the Pacific. 



Brady's earliest figure of the species was drawn from a Pacific specimen, Challenger 

 St. 276, North of Tahiti, 2350 fathoms. 



394. Lagena squamosa (Montagu) (F 197) (SG 243). 

 Four stations: 175, 200, 386; WS 482. 



Only a single specimen at each station, none quite typical, the best at St. WS 482. 



395. Lagena squamoso-alata, Brady (Plate VII, figs. 24, 25). 



Lagena squamoso-alata, Brady, 1879, etc., RRC, 1881, p. 61 ; 1884, PC, p. 481, pi. Ix, fig. 23. 



One station: 363. 



A very fine specimen was found at St. 363, off Zavodovski Island, in the South 

 Sandwich group, depth 329 m. It agrees generally with Brady's figure, but has a basal 

 cleft in the wing, and lacks the ring of areolae surrounding the central area. The type 

 was from ofi^ West Ireland, 173-1445 fathoms, and I know of no other record, so that its 

 occurrence in the Antarctic is noteworthy. 



Length 0-5 mm. ; greatest breadth 0-26 mm. ; thickness o-i6 mm. 



In L. squamoso-alata the areolae are covered in with a very delicate outer shell, quite 

 transparent; similar double wall structure is found in L. heronalleni (No. 348), L. 

 sqiiamoso-marginata , Parker and Jones, L. scottii, Heron-Allen and Earland (No. 387), 

 and L. texta, Wiesner (No. 407). No mention of this feature occurs in Brady's descrip- 

 tion of his species, but it can be seen in the type specimen in the British Museum 

 (Natural History) which is in perfect condition, and the structure is clearly indicated 

 in the type illustration by Hollick. 



396. Lagena squamoso-sulcata, Heron-Allen and Earland (F 196A) (SG 244) (Plate 

 VII, figs. 26-28). 



Six stations: 170, 175, 363, 385; WS 468, 482. 



Rare or very rare everywhere but a fine series of specimens, especially at Sts. 170 and 

 WS 468. At the latter station a very remarkable abnormality was observed, a double 

 shell in which the oral end of a typical L. squamoso-sulcata was joined to the base of a 

 specimen of L. costata. Such abnormalities are evidence of the trifling zoological im- 

 portance attributable to specific distinctions in the Foraminifera. Wiesner records this 

 species (W. 193 1, FDSE, p. 119, pi. xxiii. Stereo-fig. h), but his photographic figure is 

 not clear. He also records a new species L. (Entosolenia) scalariforme-sulcata (W. 193 1,
