outer area and extending to the periphery. Internally the 

 pillars, in vertical section, are seen to be numerous and slender ; 

 in median section the megasphere is subcircular and immersed 

 in the semi-lunar secondary chamber. Equatorial chamberlets 

 spatuliform, rarely hexagonal. The meg;i sphere in a Batesford 

 specimen has a diameter of .195mm. The megasphere of the 

 E. Indian examples of this species is exactly similar in shape to 

 the Victorian examples, and would consequently, according to 

 R. Douville, belong to the same geographical race. 



L. tournoueri was first described from Mediterranean 

 examples by MM. P. Lemoine and R. Douville, and it has since 

 been recorded from Borneo by H. Douville in beds referred to 

 the Burdigalian. 



In the original description, the diameter of the test of this 

 species is given as about 2mm., and our Batesford specimens 

 have the same dimensions.

The test of this species is usually com])aratively large and 

 thin ; the diameter of some Batesford specimens measuring as 

 much us loiiiiii. The swollen central area is distinctly granu- 

 late, whilst the thin peripheral portion has the granules much 

 finer. In vertical section the pillars are seen to be numerous 

 and very slender in the peripheral flange-like portion, and 

 gradually thicken towards the region of the umbilical boss, 

 whcic the}' protrude from the surface as distinct papillae. The 

 equatorial chambers of this species are distinguished from those
