SYSTEMATIC ACCOUNT 



Note. To economize space, no synonyms are given for species which have already been 

 described in the Report on the Falkland area. For purposes of reference, the Falkland 

 No. is printed in brackets after the specific name: e.g. Biloculina murrhyna, Schwager 



(F3)- 



Order FORAMINIFERA 



Family MILIOLIDAE 



Sub-family MILIOLININAE 



Genus Biloculina, d'Orbigny, 1826 



Note. The BiloaiUnoe have been determined from external characters only, as time 

 has not allowed for the preparation of sections. The genus is difficult to diagnose with 

 certainty, owing to the lack of superficial distinctions. 



1. Biloculina murrhyna, Schwager (F 3). 

 Three stations: WS 429, 521, 522. 



Rare everywhere and the specimens are small and pauperate, the best being at WS 

 522. All the stations are in deep water, between 2000 and 4000 m. 



2. Biloculina serrata, Bailey (F 4). 

 One station: WS 523. 



A single weak and broken specimen. The serration is confined to the aboral edge. 



3. Biloculina bradyi, Schlumberger. 



Biloculina ringens, Brady, 1884, FC, p. 142, pi. ii, fig. 7. 



Biloculina bradyi, Schlumberger, 1891, BGF, p. 557 (in the reprints p. 170), text-figs. 15-19, 



pi. X, figs. 63-71. 



Five stations: 27, 45, 126; WS 154, 177. 



Common at several of the stations; the best specimens at WS 154 and WS 177.
