 Micr. Soc. ser. 2, vol. vi. p. 747, pi. xiv. tig. 27. 



This species was described for the first time from tlie London 

 Clay o£ Piccadilly. The specimens from the Arabian Sea agree 

 very closely with the fossil ones. 



Found in Sample No. 5, rare.

Found in Sample No. 4, very rare ; No. 6, rare.

" Faintly striate specimen." — See Brady, 1884, Chall. Eep. 

 vol. ix. p. 503, pi. Ixiv. fig. 28. 



This variety differs from the type form in having the basal half 

 of each chamber ornamented with numerous fine prickles, which 

 fade off into faint strife towards the middle of the bulb. The 

 general contour of the test of this variety agrees with that of the 

 type ; and the examples found are well-developed in point of size. 

 Length about i inch (5 mm.). 



Dr. Brady has figured a specimen which is undoubtedly referable 

 to the above variet}'-, though it is not so strongly ornamented as are 

 the specimens from the Arabian Sea. For this reason I venture to 

 separate them from the smooth typical forms by a varietal name. 



Found in Sample No. 1, rare; No. 3, very rare; No. 4, rare ; 

 No. 5, very rare.

This species is well known as a Tertiary fossil, Lamarck having 

 found it in the Middle Eocene of the Paris Basin ; and it is also
