line, but is more irregular in contour and composed of very- 

 coarse material compared with the latter. The septation also 

 is much less distinct in H. microspirale, and the chambers 

 (as far as can be seen) not nearly so numerous. 



H. microspirale is represented by three specimens from the 

 Cambridge Greensand of Swaffham, Cambridgeshire. 



Haplophragmium pseudospirale (Williamson). 



P?-oteoni?ia pseudospiralis, Williamson, 1858, Recent Foram. Gt. Britain, 



p. 2, pi. i. figs. 2 & 3. 

 Haplophragmium pseudospirale, Siddall, 1879, Catal. Brit. Rec. Foram. 



p. 4 ; Brady, 1884, Rep. Chall. vol. ix. p. 302, pi. xxxiii. figs. 1-4. 



This species is generally larger than H. cequale (Romer) 

 and essentially differs in the compressed form of the com- 

 mencement. 



Several specimens were found in the washings from 

 Swaffham. The species is one of those which were not 

 noticed in the Gault of Folkestone. 



Haplophragmium globigeriniforme (Parker and Jones). 



Lituola nautiloidea, var. globigeriniformis, Parker and Jones, I860, 



Phil. Trans, vol. civ. p. 407, pi. xv. tigs. 46 & 47. 

 Haplophragmium globigeriniforme (P. & J.), Chapman, 1892, Journ, 



R. Micr. Soc. p. 324, pi. v. fig. 16. 



Several specimens of the above species were found at 

 Swaffham ; in some cases the tests were attached to extra- 

 neous objects. The species was also recorded by G. R. Vine 

 from Cambridge.

P. cenomana is rather frequent in the washings from 

 Swaffham, and it is generally found attached to the coarser 

 glauconite fragments found therein. Perner gives some 

 excellent figures of this interesting form, which he found in 

 the Cenomanian of Bohemia.
