 form. 



One specimen from the Pebble-beds, Littleton. 



Family NUMMULINID^E. 

 Subfamily PonsioiEtioji.

 p. 730, pi. cix. figs. 14, 15, and 16 ? 



This species has been noted from beds of Miocene age, and others 

 of later date. 



One specimen was found in the Bargate Pebble-beds at Littleton, 

 which is not very typical, but somewhat closely resembles fig. 16 in 

 the ' Challenger ' Rep. (loc. cit.). 



Polystomella, Lamarck. 



139. Polystomella ACiTLEATA, d'Orbigny.

 figs. 27, 28. 



This species was originally described from the Miocene ; and it 

 occurs in the Bargate Pebble-beds at Littleton (two specimens). 



In the foregoing notes upon the foraminifera of the Bargate Beds 

 of Surrey, 139 species and varieties are recorded. 



Of these, 11 are described for the first time. There are, besides, 

 107 which have hitherto been unrecorded (so far as I am aware) 

 from beds of Neocomian age. 



The following 10 species and varieties have been known previously 

 from recent deposits only, namely, Haplophragmiumfoliaceum, Brady ; 

 Virgulina subdepressa, Brady ; Ehrenbergina pupa (d'Orbigny) ; 

 Polymorphina sororia, Reuss, var. cuspidata, Brady ; P. oblonga, 

 Williamson ; P. regina, Brady, Parker, & Jones ; Discorbina 

 Bertheloti (d'Orbigny) ; D. concinna, Brady ; D. Vilardeboana 

 (d'Orbigny) ; and D. araucana (d'Orbigny).
