The specimens from Springvale are remarkable for size, ex- 

 ceeding eight inches in length. The diameter varies from 3^ to 

 5 inches. Like all shells of the Genus the characters vary with 

 age and growth. The apical Whorls are tuberculated or poly- 

 gonal and cancellate like F. textilis which is probably a form of 

 this : the later ventricose whorls are smooth only showing light 

 spiral striation. The most slender example simulates Achatina 

 reticulata (an African landshell) in figure. The three columellar 

 plaits are very strong. See for further remarks on this species 

 my paper on the Haitian Fossils, Journ, Geol. Soc, 1876, 

 page 523.

There is only one example of this species, and it was entire- 

 ly invested externally with an organism like Membranipora, 

 which on examination proves to be more like Stromatopora. On 

 the spire, the covering forms a thin layer only, but on the last 

 whorl near the Aperture the incrusting organism forms a Boss of 

 several concentric layers. It resembles Carpentaria but there 

 are no large Apertures. The likeness to Orbitoides (see Carpen- 

 ter, Journ. Geol. Soc, 1850, PI. vii) should not be overlooked.

Casts only, but retaining sufficient of the shell substance to 

 make the determination certain.
