3. Manselia tkichina, S. Buclcman. Suppl., Plate X, figs. 14 — 16. 



Description. — Platyleptogyral, subconcavumbilicate, subcostate to striate. 



Distinction. — From the other species by the character of the ornament. 



Localities and Strata. — Dorset : Horn Park, near Beaminster, from a greyish 

 matrix, evidently below the ironshot ; Bradford Abbas, Paving Bed. And a 

 slightly more costate specimen, Normandy : Feuguerolles, " Murchisonae, upper 

 part" (M. L. Brasil). 



Date of Existence. — Murchisonae hemera. 



A species possibly to be assigned to this genus is — 



18S6. Ammonites Muuchisonje acutus, QuenstcJt. Amm. (Schwab. Jura, pi. lix, fig. 3. 



Its position would be between subfalcata and trichina. 



XVIII. Genus — Apedogyria, 1 S. Buchman. 

 (Type — Apedogyria patellar ia, sp. n.) 



Definition. — Subplatyleptogyral, latumbilicate ; subdensiseptate, 

 subbrevi-sublati-lobate ; laterally flexiradiate ; peripherally sub-anguli- 

 radiate, subtabulate, parvi-nonsepti-carinate. 



Distinction. — Much compressed like the last two genera, but more 

 umbilicate. From Hyattina, the shorter, broader lobes of the suture- 

 line form an excellent distinguishing character. FiCt " |J;~JJ adial

 periphery subtabulate. 



Remarks. — The flat sides of the whorls and the slight increase in thickness 

 give this species a peculiar plate-like appearance. 



Localities and Strata. — Dorset : Chideock Hill, from the " Wild Bed ; " Marston 

 Road, near Sherborne, probably from below the ringens bed. Foreign : Nor- 

 mandy, Feuguerolles. Bayles specimen is from "Lias superieur, Eterville
