LAGENIDAE 119 



Genus Cristellaria, Lamarck, 18 12 



262. Cristellaria crepidula (Fichtel and Moll) (F 268). 

 One station: WS 418. 



Only a single very small specimen. The absence of this species at other stations is 

 quite extraordinary. 



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

 Two stations: WS 522, 523. 



Extremely rare and small, the best specimen at WS 523. 



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

 One station: WS 522. 



A single small specimen. 



265. Cristellaria convergens, Bornemann (F 281). 

 One station: WS418. 



A single small specimen only. 



Sub-family POLYMORPHININAE 

 Polymorphina, d'Orbigny, 1826 



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

 One station: WS 521. 



The aboral half of a large specimen was found at WS 521 ; it is worthy of record only 

 on account of the depth (3780 m.) at this station which lies in the deep water between 

 the Falkland Islands and South Georgia. The species is normally of shallow water 

 habitat, but Brady records "exceedingly small" specimens at 1990 fathoms in the 

 South Atlantic and at 2350 fathoms in the South Pacific. 



267. Polymorphina williamsoni, Terquem (F 285). 

 One station: WS 314. 



A single specimen only. 



268. Polymorphina compressa, d'Orbigny (F 292). 

 Three stations: 149; MS 14; WS 33. 



A few very minute and pauperate specimens are with some hesitation referred to this 

 species. 



Genus Uvigerina, d'Orbigny, 1826 



269. Uvigerina canariensis, d'Orbigny (F 294). 

 One station: WS 429. 



A single poor specimen.
