-20 HALKYARD, Fossil Foraminifera of the Blue Marl 



solid. This view is supported by the fact that my single speci- 

 men is greyish white in colour and certainly shows a larger 

 proportion of cement to sand than is usual. 



(The specimen is most unconvincing. We are not even 

 satisfied that it is a Rhizopod. The specimen differs in every- 

 thing — shape— texture — aperture — from the type, which would 

 be very unlikely, to survive fossilization owing to its construc- 

 tion.) 



Genus Psammosphaera, Schulze. 



32A. [Psammosphaera fusca, Schulze.] 



\Psammosphcera fusca, Schulze, 1874, R. p. 113, pi. II, fig. 8.

Genus Aschemonella, Brady.

PI. I, fig. 3.

 Aschemonella catenata, Brady, 1884, Chall. Rep., p. 271, 



pi. XXVII, figs, i-ii; and pi. XXVII A, figs. 1-3. 



Two fragments consisting of three chambers were found 

 in 1893. As will be seen from the drawing here given this 

 closely resembles in the form of the chambers one of the figures 

 given by Brady (fig. 4, pi. XXVII). My specimens have per- 

 haps a slightly rougher test and have the chamber cavities 

 filled with calcite. 



FAMILY LITUOLIDiE. 



SUB-FAMILY LITUOLIN^. 



Genus Reophax, Montfort. 



34. Reophax fusiformis (Williamson), 



Proteonina fusiformis, Williamson, 1858, Recent British 



Foram. p. 1, pi. I, fig. 1. 

 Reophax fusiformis, Brady, 1884, Chall. Rep., p. 290, pi. XXX, 



figs. 7-1 1. 



Very rare, one specimen only found. 



(This specimen is not in our opinion identifiable with 

 certainty.)
