simply limbate, as M. obliqua and CristeUaria Gosce, Reuss,^ or granulato-liinbate, as 

 Margimdina Wetlierellii, Jones," and CristeUaria decorata, Reuss.^ A fifth series contains 

 those which have the chamber-walls swollen or thickened by bars transverse to the axis of 

 the shell {31. trilobata, D'Orb.*), or knobbly, as MarginuUna Hochstetteri, Stache,^ and 

 Hemicristellaria pajjillata, Stache.^ In others the growth of coarse granules is carried to 

 so great an extent that they encroach on each other, leaving only irregularly reticulate 

 fissures, or sunken lines, on the exterior, as Stache's Hemicristellaria verrucosa? Lastly, 

 a group may be formed of the prickly Margi/iulincB, with M. Idrsuta, D'Orb.," as a centre. 

 But all these graduate one into the other, as respects both form and ornamentation.
