704 MR. E. CHAPMAN ON THE BARGATE BEDS OF SURREY. [Nov. 1 894, 



44. Virgulina subdepressa, Brady. 



V. subdepressa, Brady, ' Challenger ' Rep. vol. ix. (1884) p. 416, 

 pi. Hi. figs. 14-17. 



One specimen, agreeing minutely with Dr. Brady's description of 

 a form affecting deep waters (1850-2350 fathoms) of the South 

 Pacific and South Atlantic Oceans, was found in the Bargate 

 Pebble-beds at Littleton. 



Bolivina, d'Orbigny. 



45. Bolivina textilarioides, Reuss. 



B. textilarioides, Reuss, Sitzungsb. Akad. Wissensch. Wien, 

 vol. xlvi. (1862) p. 81, pi. x. fig. 1. 



Three specimens of this species, which is a well-known Gault 

 fossil, were found in the Bargate Pebble-beds at Littleton. They 

 measure from jfa to ^\ inch (0'21 to 0*42 mm.) in length. 



46. (?) Bolivina dilatata, Reuss. 



B. dilatata, Reuss, Denkschr. Akad. "Wissensch. Wien, vol. i. 

 (1849) p. 381, pi. xlviii. fig. 15. 



The two specimens found in the Bargate Pebble-beds at Littleton 

 are doubtfully referred to the above species, since instead of having 

 narrow and oblique chambers they have them broad and less in- 

 clined, as in B. textilarioides. The general form of the test is, 

 however, comparable with Reuss's species. 



Subfamily Cassidulinin-e. 

 Cassidueina, d'Orbigny.

This interesting species has been previously recorded as a fossil 

 from the London Clay. 1 Dr. Brady's specimens were found in deep- 

 sea deposits at from 435 to 2750 fathoms. 



Two specimens from the Pebble-beds, Littleton.
