LAGENIDAE 173 



Three stations: 384, 385; WS 403. 

 Extremely rare at all stations. 



444. Polymorphina fusiformis, Roemer. 



Polymorphina fiisiformis, Roemer, 1838, CNTM, p. 386, pi. iii, fig. 37. 



Polymorphina fusiformis, Brady, Parker and Jones, 1870, P, p. 219, pi. xxxix, fig. 5, and wood- 

 cut e. 

 Pyrulina fusiformis, Cushman and Ozawa, 1930, P, p. 54, pi. xiii, figs. 3-8. 



Two stations: 385; WS 469. 



Extremely rare, but a very good specimen at St. WS 469. 



445. Polymorphina angusta, Egger (Plate VIII, figs. 3,4). 

 Polymorphina angusta, Egger, 1857, MSO, p. 290, pi. xiii, figs. 13-15. 



Polymorphina lanceolata {pars), Reuss, 1870, FSP, p. 487, no. 12; von Schlicht, 1870, FSP, 



pi. xxxi, figs. 2-4. 



Polymorphina angusta, Brady, 1884, FC, p. 563, pi. Ixxii, figs. 1-3. 



Six stations: 384-6; WS 205, 403, 468. 



Frequent at St. WS 403, where some of the specimens were slightly hispid, rare or 

 very rare elsewhere, but identical with the form figured by Brady. This is a character- 

 istic species in deep water, and appears to me to be identical with Egger 's species. 



P. angusta appears to have been overlooked in Cushman's and Ozawa 's monograph. 

 P. angusta, Brady non Egger, figures as a synonym of P . fusiformis (C. and O. 1930, P, 

 p. 55), but the reference given is to Brady's figures of P. sororia var. cuspidata, which is 

 also referred to in their text. 



Brady's form is so constant and widely distributed in deep water that I think the 

 name should be retained. He himself remarks that while originally of opinion that 

 Egger's fossil was merely a variety of P . fusiformis , he had changed his view after study- 

 ing a series of recent specimens. 



446. Polymorphina gibba, d'Orbigny (F 287). 

 Four stations: 384-6; WS 403. 



Very rare at all the stations, which are in the deep water of the Drake Strait. Single 

 specimens only were found, except at St. 385. At St. 384 the specimen is fistulose. 



In addition to these stations, a single specimen was found at St. 181 in the Palmer 

 Archipelago, depth 160-335 "^- ^^ ^^ clearly a fossil, a cast in calcite, and its significance 

 must be considered in the light of the geological evidence contained in Macfadyen's 

 report on the Fossil Foraminifera from the Burdwood Bank (M. 1933, FFBB). It is 

 probably identical with the Globulina gibba var. globosa which he records. 



447. Polymorphina problema, d'Orbigny (F 289). 

 One station: WS 403. 



A single large and fistulose specimen was found at St, WS 403, depth 3721 m. 



448. Polymorphina extensa, Cushman (Plate VIII, fig. 5). 



Polymorphina lanceolata (pars), Reuss, 1870, FSP, p. 487, no. 12; von Schlicht, 1870, FSP, 

 p. 82, no. 476, pi. xxxi, figs. 25-9.
