172 DISCOVERY REPORTS 



Sub-family POLYMORPHININAE 

 Genus Glandulina, d'Orbigny, 1826 



438. Glandulina laevigata, d'Orbigny (F 248) (SG 252). 

 Five stations: 170, 175, 181, 196; WS 482. 



Except at St. 175 in the Bransfield Strait (200 m.), where the species is frequent and 

 well developed, specimens are rare or very rare. The stations are confined to the small 

 area between Clarence Island, which is midway between the South Orkneys and the 

 South Shetlands, and the Palmer Archipelago to the south of the South Shetlands. 



This species, which for over a century has been regarded as a Nodosaria, must now 

 be transferred to the Polymorphininae, in consequence of Ozawa's discovery that the 

 microspheric form is biserial in the early stage. 



Genus Polymorphina, d'Orbigny, 1826 



439. Polymorphina lactea (Walker and Jacob) (F 283) (SG 266). 

 One station: 384. 



Two small specimens were found at St. 384 in the Drake Strait, depth 3713 m. 



440. Polymorphina williamsoni, Terquem (F 285) (SG 267). 

 One station: 177. 



A single small but typical specimen was found at St. 177 in the Bransfield Strait, 

 depth 1080 m. 



441. Polymorphina ligua, Roemer (F 292) (SG 268). 



Polymorphina ligua, Roemer, 1838, CNTM, p. 385, pi. iii, fig. 25. 



Polymorphina lingua, Reuss, 1855, TD, p. 248, pi. vii, fig. 77. 



Polymorphina compressa, d'Orbigny {non Philippi), 1846, FFV, p. 233, pi. xii, figs. 32-4. 



Polymorphina subcompressa, d'Orbigny, 1849, etc., PP, 1852, p. 159, no. 2976. 



Pseudopolymorphina ligua, Cushman and Ozawa, 1930, P, p. 89, pi. xxii, figs. 5, 6. 



Three stations: 164, 175, 190. 



Very rare everywhere, and all small specimens except a single large individual at 



St. 175- 



This species was listed in the previous reports as P. compressa, d'Orbigny. Under the 



rules of priority this name must give way to P. ligua, Roemer, an unfortunate change, 



particularly in view of the supersession of a name which has been in general use for 



three-quarters of a century, in favour of an orthographical error. 



442. Polymorphina sororia, Reuss (F 286). 

 Two stations: 384, 385. 



Small specimens are rare or very rare at these two stations, in the deep water of the 

 Drake Strait. 



443. Polymorphina cylindroides, Roemer. 



Polymorphina cylindroides, Roemer, 1838, CNTM, p. 385, pi. iii, fig. 26. 

 Polymorphina cylindroides, Brady, Parker and Jones, 1870, P, p. 221, pi. xxxix, fig. 6. 

 Pyrulina cylindroides, Cushman and Ozawa, 1930, P, p. 56, pi. xiv, figs. 1-5.
