430. Cristellaria compressa, d'Orbigny (Plate VII, figs. 44, 45). 

 Cristellaria compressa, d'Orbigny, 1846, FFV, p. 86, pi. iii, figs. 32, 33. 



One station: 385. 



The single specimen from 3638 m. in the Drake Strait, which is figured, appears to 

 be near d'Orbigny's original figure and description. D'Orbigny's species was from the 

 Miocene of Baden. The subsequent figures of Brady (B. 1884, FC, p. 538, pi. cxiv, 

 figs. 15, 16) and Fhnt (F. 1899, RFA, p. 315, pi. Ixii, fig. i) represent a diff'erent 

 organism. 



The specimen is o-8o mm. long. 



431. Cristellaria gibba, d'Orbigny (F 274) (SG 263). 

 Eleven stations: 170, 175, 180, 384-6; WS 403, 469, 481, 482, 513. 



Very rare everywhere; most frequent at St. 170, where very good specimens were 

 found, also fossils. Single very good specimens also at Sts. WS 469 and 482. The 

 stations are scattered over the entire area except the Weddell Sea, and show a great 

 range of depth between 100 m. at St. WS 482 and 4773 m. at St. 386. The specimens 

 from the deeper stations are generally very small. 



432. Cristellaria rotulata (Lamarck) (F 276). 

 Seven stations: 170, 175, 363, 386; WS 469, 482, 507B. 



Only a single specimen at each station, the best at St. 363 in the South Sandwich 

 Islands, 329 m., and at St. WS 507B in the Bellingshausen Sea, 580 m. 



433. Cristellaria cultrata (Montfort) (F 278) (SG 264). 

 Three stations: 385 ; WS 403, 507 a. 



Only a single specimen at each station, the best at St. 385, 3638 m., in the Drake 

 Strait. 



434. Cristellaria articulata (Reuss) (F 279). 

 One station: 170. 



A single good specimen of the regular type was found at a depth of 342 m., off" 

 Clarence Island. 



435. Cristellaria crassa, d'Orbigny (F 280). 

 Two stations: WS 505, 507 b. 



Two very good specimens at St. WS 507B, and a smaller specimen at St. WS 505. 

 Both stations are in the Bellingshausen Sea. 



436. Cristellaria convergens, Bornemann (F 281) (SG 265). 

 Three stations: 383-5. 



Single specimens were found at these three deep-water stations in the Drake Strait, 

 inside the convergence. 



437. Cristellaria angulata (Reuss) (F 282). 

 One station: 363. 



A single specimen, similar to those figured from the Falkland Islands area, was found 

 at St. 363 in the South Sandwich Islands, at a depth of 329 m.
