101. Ovulites globulosa, Defr. 1825. Diet, xxxvii. p. 134. 

 (Velins du Mus. no. 48. f. 9.) This is described as being smaller 

 than a mustard-seed, almost spherical, the apertures at each end 

 scarcely discernible. Fossil at Grignon and Villiers (Seine et 

 Oise), and Courtagon near Bheims. Defrance also speaks of a 

 similar little globular fossil, of the same size, but solid and 

 more spherical, found in the same bed at Villiers, and also at 

 Bimini. 



The first of these is most probably a globular Ovulites, such 

 as occur in the Grignon deposits; and the latter may be 

 spherical atoms of carbonate of lime, not unusual in some marine 

 deposits.
