the chambers take on the Flabelline character to a very con- 

 siderable extent. De Montfort copied Soldani's figure under 

 the name Scorftmus navicuka-is. V'lg. C also, and others 

 figui-ed by Soklani, show the Flabelline tendency. See also 

 fig. 86, wJiich, however, is both limbate and tuberculate.

Soldani's figures referred to by D'Orbigny are unsatisfactory 

 as affording a basis for a distinct name. They are somewhat 

 irregular suborbicular Cristellaria ca.<isis. with a more or less 

 limbate septa and some scattered umbilical granules.

Two subvarieties of C. calcar. Fig. S (like the next, 

 fig. Ss) .shows no segmentation, but has traces of umbilical 

 radiate limbation, and numerous widely scattered granules 

 over the round })art of the shell. Tluis it somewhat approaches 

 the better formed figs, y^* '"''j 1^^- •'^^ ("^^- 114). Fig. T is an
