The largest number of known specimens {R. globulifera and 

 R. aculeata) occur in the Cretaceous Formations — thus, 26 in 

 the Gault (chiefly at^Folkestone), whilst the Lower Greensand, 

 Eed Chalk, Lower and Upper Chalk together have yielded 12. 



Addendum. — As this memoir was going through the press, we 

 met with the descriptions and figures of two interesting and rare 

 forms of Protozoa, which seem to be closely related to Ramulina, 

 in one of the late Dr. H. J. Carter's memoirs (Ann. Mag. Nat. 

 Hist. ser. 5, vol. v. (1880) pp. 446-448). Both of these forms 

 were arranged by him in his Testamoebiformia. One of them., 

 Solocladina pustulifera (pi. xviii. figs. 4 a~g), irregularly branch- 

 ing, repent, and attached by its root-like ends, has some apparent 

 aflB.nity to Ramulina globulifera. The other, Cysteodictyina com- 

 pressa (pi. xviii. figs, 5 a-e), coarsely reticulate, repent, and 

 attached throughout, is evidently related to R. Grimaldii. Both 

 were found by Dr. Carter in the crevices of Melobesian nodules 

 from the Gulf of Manaar.
